Re: Stormwater Pollution Prevention Plan — Recreation and Parks Department
Main Warehouse
JEC Project No. 09-149-008
Dear Mr. Allen:
The accompanying document is the Stormwater Pollution Prevention Plan (SWPPP) for the City of
Winston-Salem Recreation and Parks Department Main Warehouse (RPDMW). The purpose of this
Plan is to guide and aid the City to reduce stormwater pollution from municipal activities and sources
on the RPDMW site, and thus to comply with the City's mandate to implement Pollution Prevention /
Good Housekeeping measures in accordance with the City's National Pollutant Discharge
Elimination System (NPDES), Municipal Separate Storm Sewer System (MS4) permit NCS000247.
To ensure implementation of the Plan, certification of Plan compliance by the senior person in
responsible charge of the site is needed on the certification form which can be found on page iii.
The steps for complying with the Plan are as follows:
1. Review the Plan —Prior to adoption, RPDMW management and staff will have
reviewed the Plan and contributed to its development. Thorough review is needed to
ensure that management and staff understand their roles and responsibilities.
2. Implement the Plan—RPDMW management and staff will use the yearly schedules
provided in the SWPPP document to implement the Plan. Completed schedules and
forms should be stored in Appendix D for documentation of Plan implementation.
3. Maintain the Plan —The Plan should be reviewed/updated at least annually and as
changes in the facility, procedures, or personnel dictate. Re -certification is needed
whenever there is a change in the senior person in responsible charge of the site and
Plan.
JEWELL Engineering Consultants appreciates the opportunity to support the City in the development
of this Plan. We are available to provide continued support in its implementation.
Sincerely yours,
JEWELL Engineering Consultants, PC
C. Douglas Jewell, PE
President

SWPPP CERTIFICATION
This certification should be renewed when changes or revisions to the plan are made or
when changes in personnel dictate a shift in responsibility for implementation of the plan.
I certify, under penalty of law, that this document and all attachments were prepared
under my direction or supervision in accordance with a system designed to assure that
qualified personnel properly gather and evaluate the information submitted. Based on my

Significant SWPPP Goals
The facility should make plans to accomplish these goals in a time frame that is reasonable
without sacrificing urgency. Once the target date is determined, it should be entered into the
goal schedule. Implementation items are included on the SWPPP Master Implementation and
Tracking Schedule and should be recorded as complete on that schedule. The Plan should be
updated following the guidelines set forth in Appendix B upon completion. Items notated with
an asterisk are listed in the Feasibility Study (Section 2.1) of this Plan and may require more cost
or effort to implement.

Stormwater Pollution Prevention Plans for North Carolina
Stormwater NPDES Permits
A Stormwater Pollution Prevention Plan (SWPPP, also called herein the Plan) is a document
developed by a facility to address ways to manage, operate, and react to minimize the likelihood
of causing stormwater pollution. The Plan provides a flexible means to develop site -specific
measures of pollutant reduction and control. The Plan is an element of the Pollution Prevention
and Good Housekeeping for Municipal Operations for the City of Winston-Salem's NPDES
permit (NC000247). The Plan is to be designed to achieve two main objectives:
(1) Identify potential sources of stormwater pollution
(2) Describe the methods by which the facility will reduce the amount of pollutants
carried in the discharging stormwater
The Plan is not to be submitted to the North Carolina Department of Environment and Natural
Resources (NC DENR) Division of Environmental Management (DEM) or to the United States
Environmental Protection Agency (EPA) unless requested. The Plan should be available for
review upon request. The plan should be kept current to prevent deficiencies in the methods
described by the plan to reduce stormwater pollution.

1.1 General Location Map
The City of Winston-Salem Recreation and Parks Department Main Warehouse (RPDMW) is
located in the central portion of Forsyth County and to the east of the central business district of
the City. The facility is located in Reynolds Park just south of Reynolds Park Road, which
bisects the park. Nearby major transportation routes include Business Interstate 40 to the north,
U.S. Highway 52 to the west and Interstate 40 to the south. The general location of the site is
shown in Exhibit 1. The facility is comprised of a portion of 3 parcels and as a whole
encompasses approximately 14.6 acres. The facility's stormwater drains into Berry Branch
approximately .7 miles upstream of its confluence with Salem Creek.
Exhibit 2 shows an aerial view of the RPDMW including storm drainage outfall monitoring
points and potentially polluting activity areas. The latitude and longitude for each stormwater
discharge outfall is documented in Table 1 along with the specific receiving waters for each
outfall. Refer to Section 1.5 for a narrative description of each of these outfalls.

1.1.1 Proximity to 303d-Listed Waters
The RPDMW is located on a site that drains to Berry Branch. Berry Branch is not currently
303d-listed; however, the branch feeds directly into a section of Salem Creek that is 303d-listed
for fecal coliform. Fecal coliform is contributed by both point and non -point sources. Urban
stormwater runoff is identified as one potential source of fecal coliform for this 303-d listing.
This facility does not handle materials that contribute fecal coliform to stormwater runoff, but is
a source of urban runoff. The discharge from this facility would not directly exceed water
quality standards and may contribute very little to the impairment of Salem Creek. Wet weather
monitoring (discussed in Section 7) will allow the facility to discover and repair any conditions
that could contribute significantly to this impairment.
A Total Maximum Daily Load (TMDL) for fecal coliform approved by the United States
Environmental Protection Agency (USEPA) is in place for the 303-d listed reach of Salem Creek
(approval date September 25, 2006). The TMDL objectives require the instream fecal coliform
concentrations to meet both the instantaneous standard of 400 cfu/I00ml and the geometric mean
standard of 200 cf r/100ml. Data is not collected in Salem Creek often enough for the geometric
mean standard to apply, therefore only the instantaneous standard is used as the endpoint for the
fecal coliform TMDL in the creek. It is assumed that if the instantaneous standard is met, it will
follow that the geometric mean standard will also be met.
Winston-Salem discharges stormwater from its Municipal Separate Storm Sewer System (MS4)
under an NPDES Phase I MS4 stormwater permit. Walkertown and Kernersville (municipalities
upstream of Berry Branch that contribute runoff to Salem Creek) are both covered under NPDES
Phase II permits. Therefore, all the nonpoint source loading from the watershed area that is
inside the incorporated boundaries of the cities of Winston-Salem, Walkertown, and
Kernersville, as well as all urban areas inside the zone of influence, are included in the WLA
(Waste Load Allocation) section of the TMDL. The coverage of these permits indicates that
runoff from the RPDMW site is required to meet the standards of the TMDL.

1.2.1 Aboveground Storage Tanks (ASTs)
For the purpose of this report, an AST is defined as an aboveground storage tank that holds a
volume of liquid and/or spillable material greater than or equal to 55 gallons. General rules
regarding storage tanks apply to many specific areas at the RPDMW, so while the discussion of
each individual tank will be located within activity -specific dialog, the general rules are
presented here as a forward to those later discussions.
Secondary containment for ASTs is required by the State of North Carolina if a facility is
designated an oil terminal facility, meaning that the facility has more than 21,000 gallons of
storage capacity. The federal rule (40 CFR Part 112) for secondary containment is more
stringent, requiring secondary containment if the facility ASTs add up to a storage capacity of
1320 gallons or more. This same statute requires a Spill Prevention, Control, and
Countermeasure (SPCC) Plan for storage tanks if any of the following apply:
■ The facility could `reasonably be expected to discharge oil into or upon the navigable
waters of the United States or adjoining shorelines.'
■ The facility uses `oil in quantities that could be harmful.'
■ Storage capacity exceeds 1320 gallons.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 7

Table 3 lists the ASTs that were observed as of December 30, 2009 at the RPDMW. The
RPDMW site map, Exhibit 3b, documents the locations of these ASTs. The RPDMW facility
has three AST tanks on site. One is actually adjacent to the vegetative management building and
is reportedly out of commission, so it is not discussed in this report. The other two are located at
the east end of the main warehouse building; this area is leased to the Reynolds Park Golf Course
Management for maintenance purposes.

One of the ASTs houses unleaded gasoline (Image 1.1), while the other contains diesel fuel
(Image 1.2). Both tanks are welded metal tanks with secondary containment attached. The
unleaded tank is constructed such that no rain water accumulates, while the diesel tank does
accumulate stormwater. The unleaded tank was plugged, but the diesel tank was not plugged.
Ice inside the secondary containment of the diesel tank suggested the accumulation of rainwater.
The pavement around the diesel tank was stained and smelled of fuel. The diesel tank is not
protected by bollards and is only partially located on an impervious surface. Measures should be
taken to ensure that this tank remains plugged and proper procedures are followed when draining
the tank of accumulated rainwater (See Form #14).

4.2.2 Materials Storage
Materials storage at the RPDMW can be categorized in one of three ways: indoor storage,
covered outdoor storage, or uncovered outdoor storage. The first category of storage is primarily
confined to the Warehouse Building. A section of the Warehouse Building is used by Vegetative
Management; this section of the Warehouse Building is not discussed in this report. Another
section of the building is leased out to the Reynolds Park Golf Course Maintenance Department
(the indoor activities here are also not documented). Two other indoor storage buildings exist on
the site, one is a brick building used by Vegetative Management (also not covered in this report),
and the others are a greenhouse and storage shed used by a community outreach program called
Special Populations. The areas used by Vegetative Management are independent and thus not
covered in this report, but the area leased to the Reynolds Park Golf Course Maintenance
Department is still the responsibility of the RPDMW.
The inside of the Warehouse Building is divided into caged sections. The first holds pipes
and lumber and other solid materials, the second holds paint and painting supplies, and the third
holds field chalk and machines for applying field chalk. The next section of storage holds
cleaning supplies, pine oil, wax stripper, and buffing pads (Image 1.3). Some small -engine tools
are stored in the corner cage along with weed killer. On the east end, the sections are not caged
and hold bags of field chalk (Image 1.4), buckets of wax stripper, calcium chloride bags, bags of
sodium bicarbonate, buckets of field paint, and a few bags of QuickreteTM. The last thing on the
east end is a cabinet for solvents and paint thinner/remover. On the north wall is the wood shop,
then a section with a few chainsaws, an upstairs section with pool management supplies in small
quantities, and an ice machine. The western end of the building is a storage area for signs on the
upper level. On the first floor, there is a sign shop, a welding shop area, and an employee break
room.

While the indoor storage areas used by the Reynolds Park Golf Course and by Vegetative
Management were not observed on this site visit, the greenhouse and storage building used by
the Special Populations program were observed. This area had plants on the grounds
surrounding the buildings, in the greenhouse, and in the storage building. Some fertilizer bags
were stored outside, but not in quantities that could significantly affect stormwater runoff. The
area has no stormwater structures and runoff is overland flow.
The second classification of storage is covered storage, which is found in two locations at the
RPDMW facility: the Outdoor Storage Shed, and the Warehouse Building Loading Dock. The
loading dock area and sump area are contiguous covered areas at the south side of the Warehouse
Building. The loading/unloading dock is located at the western end and the sump area is located
at the eastern end. The materials used during pool season (Muriatic Acid, Cyanuric Acid,
Chlorine Tablets and Grains, Sodium Hypochlorite, and Trichlor Pucks) are stored in the sump
area, which is protected by a roof. These swimming pool materials are ordered all at once before
the beginning of pool season. These contiguous areas can be seen in Images 1.5-7.
Images 1.5-7 — Loading dock (left), storage at sump area (center), and vehicle/material storage
at sump area (right)
Image 1.8 — Strip drain at
Vehicle Wash Station
The sump area is categorized as the Vehicle Wash Station
because of a hose located here used to wash out field
vehicles before pulling them into the Warehouse Building.
The exposed south side of the sump area is curbed and a
strip drain collects wash water and conveys it to the
sanitary sewer system (Image 1.8). Empty barrels and a
barrel of weed killer (Image 1.7) are stored on the eastern
wall of the sump area. At the Vehicle Wash Station,
cleaning is apparently performed without detergents. The
materials used for pool maintenance are stored in the
Vehicle Wash Station area. At the time of the site visit, the
only materials stored in this location were the excess items
from the previous pool season. These materials include
chlorinated isocyanurates (tablet and granular form),
barrels of muriatic acid, bags of sodium bicarbonate
(baking soda), barrels of cyanuric acid (Image 1.5) and
buckets of calcium carbonate. Some excess field paint is
stored here as well. Due to the large quantity of materials
stored here during pool season, storage should be configured such that any spills will not escape
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 10

the Vehicle Wash Station area and can be washed into the strip drain for conveyance to the
sanitary sewer system.
The area shown in Image 1.5 is the Warehouse Building Loading Dock. Some unused pallets are
stored here, as well as a pallet of bags of rubberized mulch for playgrounds. Some empty barrels
and buckets are stored in this same area. Traffic cones and wooden barriers are stored just
outside of the covered area. The bay door shown in Image 1.5 is not opened as the facility no
longer employs an in-house mechanic. The large door to the right of this area is the entrance
door for service vehicles and deliveries to the main warehouse building.
Image 1.9 — Outdoor covered storage shed
The second area of outdoor covered storage
is the Outdoor Storage Shed, located in the
Outdoor Storage Area to the south of the
main warehouse building (Image 1.9). This
area is a sheltered area where miscellaneous
items are stored due to the fact that the
facility is required by the City to save all
inventory items. Items stored at this location
vary from multiple types of solid material
items to bags of calcium chloride pellets,
bales of straw, bags of field chalk, bags of
QuickreteTM, and buckets of field paint.
Several empty trash cans are stacked in this
area. At the time of the site visit, these trash
cans contained frozen water. Ice melt from
this area formed the runoff shown in Image 1.9.
Bags of field chalk and calcium chloride pellets are ripped open and spilled in the covered area.
The field chalk has stained the pavement, indicating that it is being washed off -site with
stormwater runoff (Image 1.10). Also, the bags of QuickreteTM have broken open, mixed with
water, and formed concrete blocks.
This area should be cleaned and if
possible, bermed or curbed on the
southern end. Sediment under the
cover suggests that runoff runs
through the covered area and off -site,
carrying with it pollutants from the
stored materials (Refer to Significant
SWPPP Goals #11-12 on page vii).

The final category of storage
at the RPDMW facility is
outdoor storage. Most of the
outdoor storage at the facility
consists of dirt, sand, gravel,
stone, and mulch. The Dirt
Borrow Lot on the eastern
part of the facility is a storage
location for a large amount of
dirt, mulch, and sand. These
materials and a dirt shredder
(Image 1.11) are used to
make dirt for the RPDMW-
maintained baseball fields.
All sides of this lot (aside
from the northern edge) show
signs of past and present
offsite sedimentation and erosion.
Image 1.11— Dirt pile and dirt shredder at Dirt Borrow Lot
The southeast corner of the Outdoor Storage Lot is the other area housing a large amount of
outdoor materials. Stone, dirt, sand, large rocks, and gravel sit in piles in this area. Two
concrete bays (Image 1.12) have been made to house gravel and mulch; the rest of the materials
are in various piles.
Image 1.12 — Concrete bays for gravel and mulch
Recreation and Parks Main Warehouse
Winston-Salem, NC
Another part of the Outdoor Storage Area
contains items along the northern
fenceline north of the Outdoor Storage
Shed. Concrete blocks and bricks are
stacked here, along with some piping and
other solid materials. The facility also
collects scrap metal in the Outdoor
Storage Area. When enough scrap metal
has accumulated, it is taken away by a
contractor. An observed issue throughout
the outdoor lot is the tendency for waste
items to be left out among other materials.
Several car batteries, bags of QuickreteTM,
and other trash items were observed.
Stormwater Pollution Prevention Plan
Page 12

4.2.3 Material Loading/Unloading
Most loading and unloading activities take place inside of the Warehouse Building at the
RPDMW facility, where work trucks load up the supplies they need for the day's work, then exit
the building through one of the three bay doors at the north end of the building. The primary
outdoor loading and unloading point is at the Warehouse Building Loading Dock at the south
side of the building (Image 1.13). The loading dock is covered by a roof. Deliveries are moved
inside the Warehouse Building (or into the Vehicle Wash Station area) by forklift. The facility
takes on the responsibility of offloading deliveries to their storage locations. Dirt, mulch, stone,
and other outdoor materials are loaded and unloaded regularly at the Dirt Borrow Lot and the
Outdoor Storage Area.
Image 1.13 — Warehouse Building loading dock area
1.2.4 Waste Management and Disposal
The RPDMW facility has several locations
where dumpsters are either stored for use at
- other sites or used by the facility. The majority
of items at the facility are saved until they are
used, or they are recycled. The empty barrels
left over from the acids the facility uses for
pool cleaning are retrieved by the supplier for a
fee. All other waste from the Warehouse
Building is disposed of in a dumpster located at
the loading dock on the south side of the
building. The dumpster is located in close
proximity to a storm drain. The dumpster is
Image 1.14 — Dumpster at loading dock missing half of the lid and the container is
plugged (Image 1.14). The structure of the
container appears to be sound. Two auxiliary dumpsters are stored at the west end of the truck
lot south of the main warehouse. These dumpsters are used when needed at recreation centers
for events. A concrete pad is in the area for the dumpsters, but they are not currently positioned
on it (Image 1.15). One of the dumpsters is rusted out, while the other is in good condition. On
the date of the site visit, some repaired dumpsters sat in the lower truck lot waiting to be moved
to their new locations at recreation facilities.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 13

A final dumpster is located at the east end of the
warehouse in the area that is leased out to the
Reynolds Park Golf Course Management. This
dumpster is in good condition and has a complete
lid. The RPDMW facility accumulates a large
amount of scrap metal through its practices; this
scrap is gathered in containers and hauled away by
contractors. The site is littered with items that it
cannot throw away due to the fact that all items
are in the city inventory. Clean-up of non -usable
items throughout this site is recommended.
Image 1.15 —Auxiliary dumpster not on pad
1.2.5 Vehicle Maintenance, Repair, and Storage
The RPDMW employs multiple vehicles of varying types during the course of the work they
perform. The majority of these vehicles are stored outside in lots at the facility. The RPDMW
sends all vehicles to Fleet Services Division for maintenance and repairs. No maintenance
involving oil or other fluids is performed on vehicles or equipment at the RPDMW. The trucks
for field work are parked in the North Vehicle Parking Lot at the north side of the Warehouse
Building and also inside the warehouse. Larger trucks (dump trucks, utility trucks) are parked in
the South Vehicle Parking Lot to the south of the Warehouse Building (Image 1.16). The trucks
on the north side of the lot belong to RPDMW, the others belong to Vegetative Management.
South of the Vegetative Management building, a gravel lot is used for storage of trailers and
trucks as well. In the Outdoor Storage Area, several trailers for different uses are stored in the
open space. Near the Outdoor Storage Shed, the facility stores a Bobcat, tractor, steamroller, and
a Link -Belt backhoe (Image 1.17). Several tractors and attachments are stored at the space
leased by the Reynolds Park Golf Course as well. A dirt shredder is stored in the Dirt Borrow
Lot on the east side of the facility (Image 1.11).

1.2.6 Vehicle Fueling
The ASTs discussed in Section 1.2.1 are used by the Reynolds Park Golf Course for fueling their
tractors and golf carts when performing golf course maintenance. The pumps for these tanks are
hand pumps with no cutoff valves. There does not appear to be any breakaway safety device and
there are no bollards protecting the diesel tank from collisions. The gasoline tank is protected by
three wooden block bollards. The secondary containment plug for the diesel tank has been
removed; the tank needs to be re -plugged and draining procedures should be followed for
releasing accumulated precipitation in the future (See Form #14). Section 2.2 also includes
guidance on the use of secondary containment structures. While not required, tank leakage can
be better contained using concrete pads instead of asphalt. Additional bollards to protect both
tanks from collisions, along with a roof to minimize stormwater exposure to fuel leaks would
reduce exposure to rainfall.
1.2.7 Vehicle Washing
v
1.18 — Vehicle Wash Station
1.2.8 Outside Processes
The RPDMW has only one place where
vehicle washing occurs called the sump area
or the Vehicle Wash Station. The sump area
is on the eastern end of the Warehouse
Building Loading Dock at the south side of
the Warehouse Building. The area slopes to
the south where a strip drain conveys the
wash waters to the sanitary sewer (Image
1.18). A curb prevents overflow from
leaving the covered area. Image 1.7 shows
this strip drain. The orange hose shown in
Image 1.18 is an air pressure hose. The air
compressor is in the corner of the sump area.
Vehicles can be pressure cleaned and
cleaned with a regular hose at this location.
The outside processes at the RPDMW consist of the movement of outdoor landscaping materials
such as stone, gravel, mulch, sand, and dirt. The Dirt Borrow Lot is described in Section 1.2.2,
as is the Outdoor Storage Area. The Dirt Borrow Lot receives dirt from construction sites when
contractors are looking for a place to dump their dirt. The RPDMW accepts deliveries for
topsoil and red clay, which it uses to make dirt for baseball and softball field diamonds. In order
to make this dirt rock and clod free, the facility uses a dirt shredder that is stored at the Dirt
Borrow Lot. The dirt shredder consists of a large of sieved drum, so airborne particulate matter
is minimal. The larger rocks and clods fall out the large open end of the machine (see Image
1.11), while the fine dirt falls through the sieve and is conveyed to a pile at the other end of the
machine. Due to this closed process, weather conditions are not taken into account when
shredding dirt (wind). The off -site sedimentation and erosion accompanying these activities is
discussed in Section 2.4.

1.4 Outfall Narrative
This section contains a general description of each stormwater discharge outfall (SDO) and SDO
monitoring points at the RPDMW facility as observed by the consultants during the site visit on
December 30, 2010. A total of two outfalls were identified and are shown on the overall facility
site map, Exhibit 3a. Because some of the outfalls are not easily monitored at the outfall itself,
some outfalls include remote monitoring points (MP). Below is a summary of the descriptive
terms used to identify the functional condition (measure of functionality) and structural condition
(measure of structural integrity) of each stormwater discharge outfall and monitoring point. The
primary factor in the scale of both of these attributes is the effect on the function of the SDO.
Oualification of Condition and Construction Ratings
Functional Condition
Very Poor —Trash/sedimentation to the point that function is negated.
Poor — Trash/sedimentation to the point that function is impaired.
Fair — Minor litter/sedimentation that poses no real threat to function.
Good — No litter/sedimentation
Structural Condition
Failed — Structure failure such that the structure is not functioning.
Compromised — Deterioration of structure that may impair function.
Stable — No significant deterioration of structure.
Individual Outfall Narratives
SDO-001
SDO-001 is a pipe that discharges into a ditch that leaves the site at Berry Branch of Salem
Creek at the southwest corner of the RPDMW property at a point approximately 300' west of
Quarry Park Road. The pipe is connected to a junction box/yard inlet that combines stormwater
from the north and south sides of the Warehouse Building. The monitoring point (MP-01) for
this outfall is the pipe that enters the junction box on the east wall; it drains the south side of the
Warehouse Building. Potential pollutants include:
• Suspended solids and sand
• Trash
• Leaf litter
• Oil
• Grease
• Fuel
• Antifreeze
• Weed Killer
• Muriatic Acid
• Pro SolveTM Floor
Cleaner
• Wax Stripper
• Sodium Bicarbonate
• Hydrochloric Acid
• Cyanuric Acid
• Sodium Hypochlorite
• Field Paint
• Paint Thinner
• Field Chalk
• Calcium Chloride
Pellets
• Pine Oil
• Chlorine Tablets
• Trichlor Pucks
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 19

This pipe is in good functional condition and the structural condition appears to be stable. The
structure is not marked with any type of stormwater drainage system identification (e.g. a
stormwater medallion).
SDO-002
SDO-002 is the end of a grass channel that runs parallel to Quarry Road until its exit point south
into Berry Branch. The outfall point is located approximately 300 feet south of the two
monitoring points within the Outdoor Storage area of the RPDMW. This channel endpoint is in
good condition and the structural condition appears to be stable. See below for more details
concerning the monitoring points within the facility for SDO-002.
Monitoring Point 2A
MP-02A is a 12" concrete pipe that exits the hillside at the fence line just north of the Outdoor
Storage Shed. The pipe collects runoff from the outdoor storage area leased by the Reynold Park
Golf Course and from the gravel lot near the Vegetation Management storage building. The pipe
discharges into a ditch that runs east to a second ditch that runs south and discharges into Berry
Branch of Salem Creek at the southern end of the RPDMW property at the bridge crossing Berry
Branch. The exact monitoring location is the pipe opening at the fence line. Potential pollutants
include:
• Suspended solids and sand • Unleaded Gasoline
• Trash • Grease
• Leaf litter • Antifreeze
• Oil • Diesel Fuel
This pipe is in poor condition (sedimentation) and the structural condition appears to be stable.
The structure is not marked with any type of stormwater drainage system identification (e.g. a
stormwater medallion).
Monitoring Point 2B
MP-02B is flow concentration point at a curb approximately 15' north of the Outdoor Storage
Shed. The runoff collects and follows the curb to the south of the Outdoor Storage Shed where it
crosses the access road and enters a trench that runs south along the fence line to Berry Branch of
Salem Creek. The runoff leaves the property at the southern end of the RPDMW property at the
bridge crossing Berry Branch. The exact monitoring point is the corner of the curb at the east
end of the Outdoor Storage Shed. Potential pollutants include:
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 20

• Suspended solids and sand
• Fuel
• Trash
• Field Chalk
• Leaf litter
• Field Paint
• Oil
• Calcium Chloride Pellets
• Grease
• Straw
• Antifreeze
• QuickreteTM
The curb is in good condition and the structural condition appears to be stable. The structure is
not marked with any type of stormwater drainage system identification (e.g. a stormwater
medallion).
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 21

1.5 Significant Spills
The RPDMW has no record of significant spills within the last 3 years. A log to record any
future significant spills is included in Appendix A. The EPA has defined "significant spills" to
include releases within a 24-hour period of hazardous substances in excess of reportable
quantities under Section 311 of the Clean Water Act and Section 102 of CERCLA. Reportable
quantities are set amounts of substances in pounds, gallons, or other units and are listed in 40
CFR Part 117 and 40 CFR Part 302. Releases are defined to include any spilling, leaking,
pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or
disposing into the environment.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 22

1.6 Outfall Visual Observation Summary
A visual assessment of stormwater outfalls at the RPDMW was conducted by the consultants on
December 30, 2009. The visual assessment was preceded by 72 hours without a rainfall event.
One monitoring point (MP-02B) exhibited flow during dry weather conditions. A summary of
the observed flows and possible explanations are summarized below. All illicit connections or
improper discharges must be plugged and abandoned, authorized under a separate NPDES
permit, or re-routed to a municipal sanitary sewer system.
MP-02B
Some flow was observed along a depression to the north of the Outdoor Storage Shed. The
source of this water appears to have been frozen rainwater in unused trash barrels that was
melting in the afternoon sun. This discharge does not constitute an unacceptable non-stormwater
discharge.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 23

1.7 Outfall Certification
This plan includes a certification that all designated stormwater discharge outfalls (SDOs) have
been evaluated for the presence of non-stormwater (illicit) discharges. In the future, a designated
representative from the Recreation and Parks Department Main Warehouse will be responsible
for performing and documenting the annual non-stormwater discharge assessment and signing
the certification form for the SWPPP. Initial evaluations for non-stormwater discharges were
made during dry -weather observations of designated SDOs. A dry -weather observation is one
made after a 72-hour period without precipitation. Blank forms for making future annual Dry -
Weather, Non-Stormwater Discharge Assessments can be found in Appendix A.
An illicit discharge is defined as any discharge to the municipal separate storm sewer system that
contains substances other than stormwater, except for discharges allowed under a NPDES permit
or waters used for firefighting operations. Non-stormwater discharges often occur due to illicit
connections to the storm drain system. As a result of these illicit connections contaminated
wastewater can enter into storm drains or directly into local waters before receiving treatment
from a wastewater treatment plant. Illicit connections may be intentional or may be unknown to
the property owner and often are due to the connection of floor drains to the storm sewer system.
Such interconnections must be disconnected or covered by an NPDES permit.
Examples of illicit, non-stormwater discharge include:
• Any water used directly in a manufacturing process
• Air conditioner condensate with added chemicals
• Product -contact cooling water
• Vehicle or equipment washwater
• Sanitary wastes
• Petroleum products
Examples of allowable discharge include:
• Uncontaminated groundwater
• Foundation and footing drains
• Air -conditioner condensate without added chemicals
• Springs
• Discharges of uncontaminated potable water
• Waterline and fire hydrant flushings
• Flows from riparian habitats and wetlands
• Discharges resulting from fire -fighting
• Irrigation water (without concentrations of landscaping chemicals)
• Wash waters from buildings and pavement that contain no soap
During the investigation to determine monitoring points for the Recreation and Parks Department
Main Warehouse, no unexplained flow or illicit discharges were discovered.

2. Stormwater Management Plan (SWM)
The general format for a SWM Plan is to include a feasibility study to examine tasks of elevated
complexity or cost, a summary of material management practices, a description of all secondary
containment measures, a summary of BMPs, and a schedule for stormwater collection and
conveyance system inspection. A summary of material management practices is included in
Section 1.2 and will not be duplicated here. Additionally, all scheduled activity items are
included in the SWPPP Implementation and Tracking Schedules in the front of the Plan.
2.1 Feasibility Study
A review of the RPDMW stormwater management practices was performed. This review
resulted in generating a list of recommended action items for the facility that will reduce
pollutant discharge and/or potential pollutant discharge. Most of the ideas for stormwater
pollution prevention mentioned within this report involve simple adjustments to everyday tasks
and procedures and can be implemented at minimal cost. The following is a list of the items that
may require more cost or effort.
1. Address erosion issues at the entrance to the Outdoor Storage Area.
2. Address sedimentation issues at MP-02A.
3. Develop accountability program for Reynolds Park Golf Course leasers.
4. Develop and implement a plan to clean up the Outdoor Storage Shed area and protect it
from stormwater pass -through.
5. Evaluate the possibilities of eliminating the exposure of fuel to the open environment and
implement the most cost effective approach (As a minimum, move the diesel AST to
reside fully on impervious surface and protect it from collision with bollards).
6. Develop and implement a sedimentation management plan for the Dirt Borrow Lot.
WSESC Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 26

2.2 Secondary Containment Structures
Currently there are two secondary containment structures at the RPDMW. Both ASTs located in
the area leased by the Reynolds Park Golf Course (located at the east end of the Warehouse
Building) have secondary containment. An AST is defined as an aboveground storage tank that
holds a volume of liquid and/or spillable material greater than or equal to 55 gallons. For
reference, the regulations for secondary containment are summarized as follows:
To prevent leaks and spills from contaminating stormwater runoff, secondary
containment should be provided for bulk storage of liquid materials, storage of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals, or storage of hazardous substances. `Bulk' is defined by a single
container that has storage capacity of 55 gallons or more.
The entire containment system, including walls and floor, must be capable of
containing pollutants and must be constructed so that any discharge from a primary
containment system, such as a tank or pipe, will not escape the containment system
before cleanup occurs. Bulk storage container facilities must provide secondary
containment for the largest single container plus sufficient freeboard to contain
precipitation, nominally 110% of the volume of the container(s).
In special cases, installation of secondary containment structures or pieces of
equipment may be determined to be not practicable. In such instances, a clear
explanation and alternate methods of `equivalent environmental protection' must be
provided. Costs and economic considerations do not justify why a facility cannot
satisfy the secondary containment requirement. Justifiable reasons include:
➢ Space or other geographical limitations
➢ Local zoning ordinances, fire prevention standards, or safety considerations
➢ Installation would defeat the overall goal of 40 CFR 112 (Oil Pollution Prevention
Regulations) to prevent discharges
The following procedures for release from secondary containment should be implemented.
1) Keep drain valves in the closed and locked position except when releasing clean
stormwater in accordance with the following procedures.
2) Visually observe the accumulated stormwater or other material inside the containment.
Document these observations using Form #14 located in Appendix A of this Plan.
3) Measure the pH of the accumulated material. If the pH is in the range of 6.0-9.0 and the
visual observation indicates that the stormwater is uncontaminated, the stormwater may
be released upon approval by the appropriate SWPPP Team Member.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 27

4) Immediately notify the appropriate SWPP Team Member if contamination, a spill, or a
leak is observed during the visual observation or if the stormwater is outside of the
acceptable pH range.
5) Under the supervision of the appropriate SWPP Team Member, use proper procedures for
removing the accumulated contaminant material from the secondary containment
structure (e.g. absorbents to remove oil sheen, etc.).
6) Return drain to the closed and locked position after each release.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 28

2.3 Best Management Practices (BMP) Summary
The following is a summary of applicable BMPs for the previously discussed potentially
polluting activities taking place at the RPDMW. This site -specific discussion will cover the
BMPs being implemented for the activities described in Section 1.2: materials storage, materials
loading/unloading, and waste management and disposal, vehicle maintenance, repair, and
storage, vehicle fueling, and vehicle washing.
2.3.1 Materials Storage
BMPs Practiced:
✓ Store & handle reactive, ignitable, or flammable materials in compliance with applicable
codes.
✓ Organize materials such that inspection is not impeded or impossible.
✓ Store materials on concrete pads to allow for cleanup of spills or leaks.
✓ Inventory fluids to more easily identify leakage sources.
✓ Store drums (including empty drums) indoors when possible.
BMPs Suggested:
♦ Keep secondary containment structures plugged to avoid stormwater pollution.
♦ Use effective inventory control to reduce volume of pollutants stored on -site.
♦ Properly dispose of chemicals that are no longer in use.
♦ Cover and/or enclose storage areas.
♦ Confine storage to low -traffic, specified areas outside of drainage pathways and away
from surface waters.
♦ Inspect and sweep areas regularly to remove potential pollutants.
♦ Make cleanup supplies available.
♦ Ensure all stored items in the loading dockNehicle Wash Station area are within the
drainage area of the strip drain that is connected to the sanitary sewer system.
♦ Maintain a spill kit in close proximity to areas where materials storage poses a proximate
risk to stormwater quality.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 29

2.3.2 Materials Loading/Unloading
BMPs Practiced:
✓ Confine loading/unloading activities to a designated area.
✓ Cover loading/unloading areas with permanent cover (e.g. roofs) or temporary cover (e.g.
tarps).
✓ Perform loading/unloading activities indoors or in a covered area.
✓ Perform loading/unloading activities on an impervious pad for easy collection of
materials.
✓ Provide overhangs or door skirts to enclose trailer ends at truck loading/unloading docks.
BMPs Suggested:
♦ Inspect the loading/unloading areas to detect problems before they occur.

2.4 Current Structural Issues
Image 2.1— Example of erosion at the dirt borrow lot
The RPDMW has few structural
issues of great concern, but the
following should be addressed.
Dirt Borrow Lot
The first issue concerns the Borrow
Dirt Lot on the eastern side of the
facility. The eastern and southern
borders of this lot are sloped steeply
down to a natural channel that feeds
Berry Branch of Salem Creek. As site
topography changes with use, the
water erodes new channels off of the
lot, destabilizing the slope wherever it
exits (Image 2.1). A solution to this
issue could be to maintain a bermed
edge on these lot borders as well as
the installation of a properly constructed silt fence barrier to prevent erosion and sedimentation.
Outdoor Storage Area
A second issue also concerns erosion. To the west of the entrance road to the Outdoor Storage
Area, flow is concentrating as it exits the pavement and has eroded channels into the parking
area (Image 2.2) which will continue to grow and cause a potential for damaging equipment.
Rocks have been placed in an attempt to slow runoff at this point, but it has had no effect.
Armoring this channel could alleviate erosion occurring at this location. The third structural
issue involves the deposition of sediment at MP-02A (Image 2.3). Sediment from the channel
and from the piped stormwater has accumulated and blocked the pipe so that it is functioning at
reduced capacity.
Image 2.2 — Eroded channel

3. Spill Prevention and Response Plan (SPRP)
The Spill Prevention and Response Plan (SPRP) identifies spill prevention and cleanup
procedures for areas and processes in which spills may potentially occur. The SPRP must
incorporate a risk assessment of potential pollutant sources based on a materials inventory of the
facility. Facility personnel responsible for implementing the plan must be identified and a
responsible member of this group must be on -site at all times during facility operations that have
the potential to contaminate stormwater runoff through spills or exposure of materials associated
with the facility operations.
3.1 Materials Inventory
A materials inventory system involves the identification of all sources and quantities of
"significant" materials that may be exposed to direct precipitation or stormwater runoff at a
particular site. "Significant" materials are substances related to potentially polluting activities
such as process chemicals, raw materials, fuels, pesticides, and fertilizers. It is necessary that the
facility maintain a comprehensive potential pollutant inventory that can be completed using the
Form #6, located in Appendix A. The facility should take inventory on a monthly basis (this
activity is noted in the Preventative Maintenance, Good Housekeeping, and Inspection Schedule)
in order to reduce waste, materials stored on site, and thus the risk of stormwater pollution.
Guidance on this process is included on the back side of the form. The following initial
inventory lists materials observed during site visit on December 30, 2009. Some quantities
represent the seasonal amount on hand (not observed). The quantity of pool supplies the facility
ordered in its most recent order made in March 2010 is denoted with a T.

3.2 Spill Risk Assessment
In order to recommend procedures for responding to a spill, it is necessary to identify the areas
where spills are most likely to occur, and more specifically, areas where spills are likely to enter
the storm drain system. Based on the activities summarized in Section 1.2 and the physical
layout of the facility, three main areas of risk exist at the RPDMW site. Following Good
Housekeeping procedures should help to minimize the risk associated with the activities in these
areas.
The first area is the loading dock/sump area. Storm drains are located directly downgrade to the
south of these areas and any spills that overtopped the sump area or drained out of the loading
area would enter these storm drains. The storm drains lead directly to SDO-001, which then
enters a natural channel that feeds Berry Branch of Salem Creek.
The second area is the outdoor storage shed area. Potential pollutants stored under this covered
area should be stored on pallets or shelves to prevent contact with stormwater that flows through
the covered area to MP-02B. Spilled pollutants or contaminated runoff from this area would
contribute directly to discharge leaving the site and entering Berry Branch of Salem Creek.
The last significant risk area is the east end of the warehouse that is leased to the Reynolds Park
Golf Course. Two ASTs, a dumpster, a loading/unloading area, and several vehicles are in close
proximity to a storm drain that connects directly to MP-02A.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 37

3.3 Spill Response Team (SRT)
The Spill Response Team (SRT) can be composed of the same members as the SWPP Team,
although this dual membership is not required. The SRT is responsible for spill response, as well
as training for all other employees on how to properly respond to a spill. The SRT should also
inspect the spill kit on a regular basis (see schedule provided at the front of this report; Form #7
is located in Appendix A for this purpose) to ensure that all necessary equipment is current,
stored properly, and in the correct location. The SRT Leader is responsible for contacting off -
site parties and property owners when necessary to report spillage and to coordinate cleanup.
Team members should contact the SRT Leader in the case of a spill and then perform what spill
containment actions are safely manageable. Spill containment procedures should be addressed in
the yearly training held by the facility and be specific to location and spill kit availability.

3.4 SPRP Equipment
In the event that spill prevention measures fail, a swiftly executed response may prevent
contamination of stormwater. The spill response plan is developed based on the spill potential
scenarios identified, thus equipment necessary to combat these same scenarios should be
available. Consider the potential magnitude and frequency of spills, the types of materials
spilled, and the variety of potential spill locations. At all times during the operation of this
facility, personnel with appropriate training and authority should be available to respond to
spills. A typical spill kit, as shown in Image 3.1, includes:
• A container capable of
holding all materials
• Absorbent pads
• Material disposal bags
• Socks
• Nitrile gloves
• Dry granular absorbent
• Mounting bracket for kit
installation at any location
Image 3.1— Typical spill kit
Other supplemental safety equipment or additional spill kit items may include:
• Safety equipment such as respirators, eye guards, protective clothing
• Fire extinguishers
• Two-way radios
• Cleanup equipment such as booms, barriers, sweeps, absorbents, containers, etc.
• Devices designed to seal storm drain inlet structures
• Artificial berms for large-scale spills
• Warning signs to keep people away from spill areas
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 39

3.5 Spill Response, Containment, Diversion, Isolation,
Cleanup
This section of the SPRP is dedicated to procedures that are necessary in order to prevent
stormwater pollution after a spill. The procedures differ based on the severity of the spill and are
classified as emergency situations or non -emergency situations. The appropriate sequences of
actions are listed for both cases. Do not attempt actions that may lead to the endangerment
of you, other personnel, or any bystanders.
The actions for an emergency situation are as follows:
1. Evacuate the premises.
2. Contact 911 and other emergency responders as the situation dictates (SRT duty).
3. Attend to those in need of medical attention.
4. Notify on -site supervisors.
5. Notify the City of Winston-Salem Stormwater Division.
In the event of a non -emergency spill, the following procedures should be followed:
1. Immediately alert area occupants and supervisor.
2. Stop the spill at its source if this can be accomplished without endangering yourself or
others.
3. Isolate all potential environmental receptors (storm drains, strip drains that connect to
storm drains, etc.).
4. If the material does not pose an immediate risk to personal health, use dry absorbent or
other approved materials to clean up the spill.
5. Contact HAZMAT responders, on -site supervisors (SRT leader) as needed.
6. Notify the City of Winston-Salem Stormwater Division in accordance with guidance
provided in Section 3.6.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 40

3.6 Notification Procedures
Facility employees should be notified of a spill that could pose an immediate risk to their health
through all communication networks necessary to disseminate the information to all staff. A
staff member who encounters a spill should take whatever emergency action is warranted, then
contact the SRT Leader who will in turn contact the facility director and emergency personnel.
Except for significant emergencies, the SRT Leader, or someone he designates, is the only one
who should call off -site responders. The following numbers are for significant emergency
situations only.
Initial Notification/Emergency Response..........................................................911
Fire Marshall (Non-Emergency).....................................................(336)-773-7900

In the event of all spills, emergency or otherwise, RPDMW supervisors should be notified as
directed in Section 3.5. If the spill enters the stormwater collection and conveyance system,
notify someone in the City Stormwater Division office within 24 hours of the spill.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 42

4. Preventative Maintenance and Good Housekeeping (PM&GH)
Program
This program documents schedules of inspections and maintenance activities of stormwater
control systems, facility equipment and systems, material handling practices, and cleaning
processes. Best Management Practices (BMPs) are recommended that minimize exposure of
pollutants to stormwater and keep the facility clean. The program also helps to minimize the
risk of accidental spills and maintain an inventory of all activities and materials at the facility.
Employee training is an important facet of this program that increases the awareness of staff
members as an aid in preventing stormwater pollution. Employee training should include the
protocols for notifying and responding to spills properly.
4.1 Preventative Maintenance
Preventative maintenance involves upkeep of two separate facets of any facility; the stormwater
collection and conveyance system, and the equipment used in daily processes. A good
preventative maintenance program should include periodic maintenance and inspection of
equipment and stormwater control structures. In the case of the RPDMW, many of these
activities are already in practice, although they may lack the documentation process necessary to
classify them as a formal program.
Stormwater Collection Systems
Stormwater collection system maintenance consists of a few minor activities; visual observations
of conditions within and affecting the performance of the stormwater system (both dry and wet
environmental conditions) two times a year, regular cleaning as needed, and periodic structural
inspection. The visual observations are discussed in more detail in Section 7. The tasks that
remain to be addressed should be as follows:
• On a semi-annual basis, inlets and underground conveyances (where accessible) should
be checked for debris and cleaned if necessary.
• When policing for litter on a weekly basis, storm drains should be checked for trash and
leaf litter.
• Twice a year, a visual performance inspection of the structures should be performed
(Form #10 is included in Appendix A for documentation of these inspections).
• Structural BMPs should be inspected yearly (Form #9 is provided in Appendix A for
documentation and guidance).
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 43

Facilities and Equipment
Inspecting facilities, checking equipment, and servicing items in need of repair reduce the
occurrence of spills which in turn protects stormwater. The RPDMW has three primary
categories of items that should be inspected: moveable equipment, building systems, and ASTs.
Employees should be mindful of the condition of equipment and facilities throughout daily
routines as well as following the scheduled maintenance set forth in this plan. A suggested
schedule of these items is included in the SWPPP Master Implementation and Tracking Schedule
in the front of the Plan.
Moveable Equipment
• Observe equipment function daily for signs of equipment leakage and failure (hydraulic
fluids, fuel lines, and lubricating oils).
• Dispose of any drained fluids in appropriate manner.
• Fill fluids, change oil, perform other maintenance in accordance with manufacturer -
suggested schedules.
• Service equipment only in a controlled location and manner to minimize the possible
release of pollutants into the storm drain system.
Building Systems (e.g. HVAC, back-up generators, etc.)
• Check outdoor equipment regularly for signs of leaks and failure.
• Clean and maintain equipment according to recommended scheduling.
• Dispose of any drained fluids in appropriate manner.
ASTs
• Inspect outside the tank for signs of leakage and signs of tank structural failure on a
regular basis. A semi-annual inspection should be performed using the Semi -Annual
AST Inspection Form provided in Appendix A.
• If questions arise as to the structural integrity of an AST and/or related controls, piping,
and connected equipment, then professional help should be obtained to answer questions
or remedy problems.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 44

4.2 Good Housekeeping
While preventative maintenance refers to items that allow an organization to maintain its
equipment and facilities in good working order, good housekeeping is focused on the daily
activities and practices of a facility that maintain general cleanliness and organization. Together
these two program elements will work to reduce stormwater pollution. This section applies to
the regular activities of the facility. Refer to the schedule of activities provided at the front of the
Plan for more information.
Waste
• Provide a separate metal can for oily rags and solvent wipes for fire prevention (and to
prevent general waste contamination); do not overfill the cans and empty at least weekly.
• Inspect to ensure dumpsters are structurally sound, not overfilled, and lids are closed
daily.
• Police the facility grounds for litter weekly.
• During litter pickup, remove sediment, litter, and debris from stormwater inlet grates and
throats.
• Do not allow trash and debris to accumulate in and around loading areas, waste storage
areas, and materials storage areas.
Storage
• Maintain an active inventory of potentially polluting materials for each site.
• Label all hazardous materials appropriately; provide access to Material Safety Data
Sheets (MSDS) for all personnel.
• Store materials in appropriate containers and away from stormwater drainage paths.
• Instruct and monitor contractors on -site to ensure they follow good housekeeping in
their area of work and with the materials they use.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 45

5. Employee Training
As a part of this SWPPP, employee training schedules are required to be developed and training
provided at a minimum on an annual basis. Training should cover proper spill response and
cleanup procedures, good housekeeping and preventative maintenance activities, and should be
given to all personnel involved in any of the facility's operations that have the potential to
contaminate stormwater runoff. All facility personnel responsible for implementing the training
must be identified in this Plan. Training will include the following topics: spill prevention and
response, good housekeeping and preventative maintenance, and material management practices.
Spill Prevention and Response Training should include the following:
♦ Identify potential spill areas and drainage routes, including information on past spills and
causes.
♦ Report spills to appropriate individuals, without penalty (employees should be provided
`amnesty' when they report such instances).
♦ Handle and store materials to reduce the likelihood of spills.
♦ Implement spill response procedures.
Good Housekeeping Training should include the following:
♦ Perform regular vacuuming and/or sweeping.
♦ Promptly clean up spilled materials in a proper manner.
♦ Identify places where spill response equipment is located.
♦ Display signs reminding employees of the importance and procedures of good
housekeeping.
♦ Discuss updated procedures and report on the status of practicing good housekeeping at
every meeting.
♦ Provide instruction on securing drums and containers and frequently checking for leaks
and spills.
♦ Track and document the successful implementation of the housekeeping schedule on a
checklist or inspection forms (FORM #15).
♦ Neatly organize stored materials.
♦ Identify all toxic and hazardous substances stored, handled, and produced onsite.
♦ Discuss handling procedures for these materials.
♦ View the Winston-Salem Stormwater Division training video for good housekeeping
practices.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 46

Other useful resources for employee training:
♦ Employee handbooks
♦ Videos and Powerpoint presentations
♦ Drills
♦ Routine employee meetings
♦ Bulletin Boards
♦ Suggestion Programs
♦ Environmental excellence awards or other programs
The frequency of staff training should take into account the complexity of the organization, staff
turnover, and rate of changes in job assignments. Facilities are required to specify a schedule for
periodic training activities in their plan with a minimum of once per year. In order to evaluate
the effectiveness of a training program, it is necessary to communicate with employees to be sure
they have understood the material. Progress on training topics and dates can be tracked using the
Annual Employee Training Log located in Appendix A. The SWPP Team is responsible for
general employee training that ensures that all facility personnel are kept up-to-date with the
most recent information on stormwater pollution control and prevention, the laws and regulations
that dictate standards and practices, and the best applicable practices for pollution reduction. In
addition to educating facility staff, the SWPP Team should ensure that all outside contractors are
aware of required procedures while working at the facility, and the SRT should ensure they
adhere to all spill response procedures while on -site.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 47

6. Facility Inspection Program
This plan identifies areas of inspection that are necessary for preventative maintenance and good
housekeeping measures. The facility must designate a qualified individual to inspect equipment
and facility areas for problems and the potential for stormwater pollution. Particular attention
should be paid to areas with known potential for pollutant discharge. A follow-up procedure
should be used and records of inspections and actions kept. The SWPPT Leader will be
responsible for keeping this record of inspections and follow-up actions.
The following items/areas need regular inspection, as is set forth in the SWPPP Master
Implementation and Tracking Schedule located in the front of this Plan:
♦ All ASTs (Form #13)
o Rusting exterior
o Valves and connections
o Secondary containment structures (Pre -Release Inspection Form #14)
♦ SDOs
o Semi -Annual Stormwater Discharge Outfall Monitoring (Form #12)
o Annual Dry -Weather Non-Stormwater Discharge Assessment (Form #11)
o Structural Inspection (Form # 10)
♦ Stormwater Collection and Conveyance System (Form #10)
o Spot-check grate cleanliness
o Structural BMP Inspection (in the event of future installation, use Form #9)
♦ Vehicles and Equipment
o Leaks and bad connections
o Regular servicing
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 48

7. Qualitative Monitoring
Twice -yearly inspection of designated outfalls is required in order to determine if pollutants are
entering the storm system from the facility. These visual observations also evaluate the
effectiveness of this SWPPP plan and its proposed BMPs in reducing pollution. The wet weather
observations must be performed during a representative storm event during the first 30 minutes
after discharge commences. The observed storm should be after a period of 72 hours without
precipitation. The inspection form (Form # 12) for these observations is located in Appendix A.
If any of the following are present in unnatural amounts or concentrations, then an investigation
must be performed and the source must be eliminated.
• Odor: Discharge odors can vary widely. Some may indicate the source of
contamination. Polluted discharges may smell like a particular spoiled product, oil,
gasoline, a specific chemical, or a solvent.
• Color: Color may indicate inappropriate discharges, especially from reactive chemical
sources. Dark colors, such as brown, gray, or black are common indicators of pollution.
• Turbidity: Flows can be cloudy (moderately turbid) or opaque (highly turbid). Undiluted
discharges, such as those coming from continual flow sources or intermittent spills, are
often highly turbid. Sanitary wastewater is also often cloudy in nature.
• Floatable Matter: A contaminated flow may also contain floatable solids or liquids.
Identifying floatables can aid in finding the source of the contamination, because these
substances are usually direct products or byproducts of the manufacturing process or the
sanitary system. Examples of floatables are animal fats, spoiled food products, oils, plant
parts, solvents, sawdust, foams, packing materials, and fuel.
• Deposits and Stains: Deposits and stains (residues) are any type of coating that remains
after a non -storm water discharge has ceased. Deposits or stains usually are of a dark
color and usually cover the area surrounding the storm water discharge. They often
contain fragments of floatable substances, and, at times, take the form of a crystalline or
amorphous powder.
• Vegetation: Stormwater pollutant discharges often affect surrounding vegetation.
Pollutants often cause a substantial alteration in the chemical composition and pH of the
discharge water, which can affect plant growth even when the source of contamination is
intermittent. The vegetation surrounding the discharge will show the effects of the
contamination.
• Erosion and Deposition: Erosion can often be found in the vicinity of outfalls where
water can undercut outfall pipes or degrade trench structures. If water appears muddy or
stormwater structures are blocked by sediment, there is likely a erosion and deposition
problem somewhere in the drainage area of the outfall.
Recreation and Parks Main Warehouse Stormwater Pollution Prevention Plan
Winston-Salem, NC Page 49

8. SWPPP Responsible Party
A Stormwater Pollution Prevention Plan must identify specific employees responsible for the
overall coordination, development, implementation, and revision to the Plan. These employees
will form the SWPP Team. Responsibilities for all components of the Plan should be
documented and SWPP Team position assignments provided.
Exhibit 4 on the following page is the SWPP Team Organization Chart that was established
during the initial development of this Plan. The chart presents schematically the structure of the
Team and designates specific RPDMW staff positions for participation on the Team. The SWPP
Team organization should be reviewed at least once annually by the designated responsible party
chosen by the RPDMW to represent the facility and maintain the SWPPP. A copy of Form #2 in
Appendix A should be used to name the SWPP Team members and to make any required
adjustments to the RPDMW staff positions participating on the SWPP Team. The back side of
Form #2 can be used to assign individual SWPP Team member responsibilities. The assignment
of responsibilities of the individual SWPP Team members should be reviewed at least once

Potential Pollutants Inventory Procedure Guidance
Keeping an up-to-date inventory of all potential pollutant materials (hazardous and non-
hazardous) present on -site will help track how materials are stored and handled onsite, help
identify which materials and activities pose risk to the environment, and help keep material costs
down by reducing overstocking. The following instructions explain the basic components of a
complete materials inventory:
♦ Identify and list all chemical substances present in the workplace. Walk through the
facility to visually identify the materials present and review the purchase orders from the
previous year to identify materials that may have been missed during the walkthrough.
Obtain the Material Safety Data Sheet (MSDS) for each chemical substance.
♦ Label all containers to show the name and type of substance, stock number, expiration
date, health hazards, suggestions for handling, and first aid information. This information
can usually be found on the MSDS. Unlabeled chemicals and chemicals with
deteriorated labels are often disposed of unnecessarily or improperly.
♦ Clearly mark on the inventory all hazardous materials that require special handling,
storage, use, and disposal considerations.
♦ Improved material tracking and inventory practices, such as instituting a shelf -life
program, can reduce the waste that results from overstocking and the disposal of out-
dated materials. Careful tracking of all materials ordered may also result in more
efficient materials use.
♦ Decisions on the amount of hazardous materials the facility stores should include an
evaluation of your emergency control systems. Ensure that storage areas are designed to
contain spills.
♦ Eliminate outdoor storage where possible.

Secondary Containment Pre -Release Inspection
CONTENTS:
LOCATION:
Before releasing accumulated stormwater from secondary containment, complete the following steps:
Check as completed
1. Do you notice any leaks from the tank or from secondary containment? If so, notify the
appropriate facility personnel immediately. Initiate Spill Response Plan procedures if necessary.
Describe any leaks or spills if observed:
2. Inspect the accumulated water for the following:
Odor Sheen Solids
Color Clarity Foam
If any of the above conditions are noted, the stormwater is likely polluted. Refer to the qualitative monitoring
guidance in Appendix B for good benchmarks to determine whether to check the above. If any of the conditions
above indicate obvious stormwater pollution, the water should be pumped to a sanitary drain connection or cleaned
up using absorbents.
If the water is free of obvious stormwater pollution, the water should still be checked for pH levels before being
discharged into the environment. Record the pH of the water in the space below. If pH is outside of the acceptable
range of 6.0-9.0, the stormwater should be pumped to a sanitary drain connection or cleaned up using absorbents.
3. Record the pH reading of the accumulated stormwater:
If all three criteria indicate that the stormwater is safe for discharge, continue the discharge process as indicated by
your facility's guidelines. BE SURE TO RETURN THE VALVE POSITION TO THE CLOSED POSITION
AFTER THE RELEASE HAS BEEN COMPLETED.

Plan Review and Revision Guidance
This SWPPP will need to be reviewed and updated on a regular basis. Whenever the need to
change a procedure that is described in this SWPPP or to modify a control measure described
therein, this plan must be updated to reflect those changes as quickly as practicable. Updates,
corrections, revisions, or additions, should be recorded in Plan Revisions Form (Form #3)
located in Appendix A. The SWPPP is a living document that adapts as the facility changes, so
the cycle of conception to revision is a continual process as illustrated below.
Practices Inspect
Retrain Review
:5 Update 0
Some events that require prompt SWPPP revision to reflect new facility conditions include:
❖ A change in composition of the SWPPT
❖ It becomes apparent that control
measures are not stringent enough for
discharge to meet water quality
standards
❖ Construction or change in design,
operation, or maintenance at the facility
Recreation and Parks Main Warehouse

❖ A discharge violates a numeric effluent
limit
❖ An inspection of the facility determines
that modifications to the control
measures are necessary to meet
stormwater quality goals or regulations
❖ An unauthorized release or discharge
