PART 1: INTRODUCTION
The purpose of this Stonnwater Management Plan (SWMP) is to establish and define the means by which
the Town of Granite Falls will comply with its National Pollutant Discharge Elimination System
(NPDES) Municipal Separate Storm Sewer System (MS4) Permit and the applicable provisions of the
Clean Water Act to meet the federal standard of reducing pollutants in stonmwater runoff to the maximum
extent practicable.
This SWMP identifies the specific elements and minimum measures that the Town of Granite Falls will
develop, implement, enforce, evaluate and report to the North Carolina Department of Environmental
Quality (NCDEQ) Division of Energy, Minerals and Land Resources (DEMLR) in order to comply with
the MS4 Permit number NCS000602, as issued by NCDEQ. This permit covers activities associated with
the discharge of stormwater from the MS4 as owned and operated by the Town of Granite Falls and
located within the corporate limits of the Town of Granite Falls.
In preparing this SWMP, the Town of Granite Falls has evaluated its MS4 and the permit requirements to,
develop a comprehensive 5-year SWMP that will meet the community's needs, address local water
quality issues and provide the minimum measures necessary to comply with the permit. The SWMP will
be evaluated and updated annually to ensure that the elements and minimum measures it contains
continue to adequately provide for permit compliance and the community's needs.
Once the SWMP is approved by NCDEQ, all provisions contained and referenced in this SWMP, along
with any approved modifications of the SWMP, are incorporated by reference into the permit and become
enforceable parts of the permit. Any major changes to the approved SWMP will require resubmittal,
review and approval by NCDEQ, and may require a new public comment period depending on the nature
of the changes.

3.2 Existing M04 Mapping
The current MS4 mapping ncludes outfalls located within the Town of Granite Falls. In the future the
Town will be adding the following elements to the map: pipe locations, flow direction, inverts, ditches,
inlets, catch basins, manholes outfall, sizes and conditions (Reference BMP 20).
The Town of Granite Falls has a historic count of 66 outfalls per the GIS layer created; however it is not
certain that all of these are major per the defuution provided below. The Town will be verifying all
elements as mentioned above in the completion of BMW 20.

3.4 MS4 Interconnection
The Town of Granite Falls MS4 is interconnected with another regulated MS4 and directly receives
stormwater from the Town of Sawmills MS4. The number of nterconnections enter ng the Town of
Granite Falls MS4 from the Town of Sawmills is unknown due to the stone sewer not being mapped.
The Town of Granite will be in the future mapping the storm sewer lines and water flow to help
determine interconnectivity (reference BMP 20).
Currently, a limited amount of data is available. Field staff will collect further data using a GIS mapping
application to locate flow direcfion, inverts, ditches, inlets, catch basins, manholes outfall, sizes and
conditions. Staff will develop a GIS mapping application off of field techniques, data recording, and pre-
existing plans or blue prints from the Town of Granite Falls.
The MS4 does interconnect with the statewide NCDOT MS4 and includes:
a. The interconnection is receiving stormwater from the NCDOT MS4. The number of
interconnections is unknown.

3.5 Total Maximum Daily Loads (TMDLs)
The TMDL(s) listed in Table 3 below have been approved within the Town of Granite Falls, as
determined by the map and list provided on the NCDOO Modeling & Assessment Unit we Rgac. The
table also indicates whether the approved TIvIDL has a specific stormwater Waste Load Allocation
(WLA) for any watershed directly receiving discharges from the permitted MS4, and whether a Water
Quality Recovery Program has been implemented to address the WLA. Outreach education and stream
cleanup helps with the reduction of waste load allocation within approved TMDL municipalities.

3.8 Non-Stormwater Discharges
The water quality impacts ofnon-stonnwater discharges have been evaluated by the Town of Granite
Falls as summarized in Table 6 below. The unpermitted non-stonnwater flows listed as incidental do not
significantly impact water quality. The Town of Granite Falls has evaluated residential and charity car
washing and street washing for possible significant water quality impacts.
Street washing discharges are addressed under the Pavement Management Program in Part 70 of this
SWMP. The Division has not required that other non-stormwater flows be specifically controlled by the
Town of Granite Falls.
Wash water associated with car washing that does not contain detergents or does not discharge directly
into the MS4 is considered incidental. However, these types of non-stormwater discharges that do
contain detergents have been evaluated by the Town of Granite Falls to determine whether they may
significantly impact water quality. The Town of Granite Falls will address the possibility of the below
mentioned water quality impacts through public education and good housekeeping, as outlined Part 5,
BMP 3-7, and Part 10 BMP 46-48, 50, 54, 55, 57, 58 and 62 with a focus on the training of good
housekeeping practices.

3.9 Target Pollutants and Sources
In addit on
to those target
pollutants identified above, the
Town of Granite Falls is aware of other
significant
water quality issues within the permitted MS4
area.
Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWNIP, the
likely activities/sources/targeted audiences attributed to each pollutant, and identifies the associated
SWMP program(s) that address. In addition, the Town of Granite Falls has evaluated schools,
homeowners and businesses as target audiences that are likely to have significant stormwater impacts.
Within the table below
the following
target pollutants have
been commonly found to be concerns withhi
the community.
Litter: Illegal dumping has occurred and been noted by code enforcement officers within the Town.
Cases of both illegal construction waste dumping and general residential or school dumping have been
noted by code enforcement officers. This litter poses a threat to both our water bodies and the MS4
infrastructure, as the fitter can create clogs and backups that damage the pipelines leading back to the
stream. Some fitter even poses a threat to groundwater if chemical leaching or breakdown of components
into heavy metals occurs due to weathering of the litter. The dumping has been found typically road side
but also in secluded urban areas.
Sediment: Previous installed erosion control measures have been removed or fallen
Sediment buildup is largely attributed to mismanaged construction sites with fallen or incorrectly installed
sediment fences. It has been noficed in both reports from citizens and by code enforcement officers that
there are several cases of construction sites not maintaining their erosion control fences during work. This
has led to sediment buildup near storm drains, onto down slope private properties, and in some cases
causing water to build up in nearby properties as the sediment is limiting the drains ability to remove
runoff. In all cases code enforcement has responded and had the issue solved, but even being down for a
short time can prove to have significant effects. Erosion control fences are required for sediment control
permits during construction by the DEQ throughout the entire construction process.
Gray Water. Straight piping washing machines out of the house
Residents have noted a few homes have had their washing machines straight -piped out of their homes by
creating makeshift piping using water hoses exit at windows. Homes are to be connected to the
appropriate sewer system. This proves to be a source of detergents/soaps entering our storm drains in
residential neighborhoods. In addition: residential, charity, and municipal car washes allow for soaps or
waxes to enter the storm drain when vehicles are not being cleaned in the correct areas (such as vegetated
patches or in areas that do not have storm drains). This allows for toxic contaminants to enter our
waterways via the storm drain system.

Fats Oils and Grease: Health Department has noted several cases where restaurants do not empty
or own/rent grease traps for appropriate removal.
The Health Department has reported several restaurants in Granite Falls not maintaining, or even owning,
grease traps. This has led to cases of the restaurants either illegally dumping the grease or allowing the
grease to drip onto nearby impermeable surface — which would eventually lead to water quality issues.
Overflow from a lack of maintenance or throwing out the grease with general waste contributes to this
problem. This is a health violation since the grease poses a physical risk, but it also can impair water
bodies with an influx of water insoluble grease going down the storm drain.
Chemicals: Totes have been noted in industrial areas not properly labeled or stored
Town staff, along with some citizens have reported that containers of unknown/umnarked chemicals are
unlabeled in select industrial sites, leading to potential soil and water contamination, and/or incorrect spill
cleanup procedure. In addition.to not labeling the containers correctly, the Town has noted that the
containers are not being correctly stored in a way to minimize risk to the water bodies from seepage,
damage to the containers, or spills.
Animal Operations: A challenge to ensuring water quality for several factors.
Animal operations are agricuhure operations that raise cows, pigs, chickens, or other livestock as a
product, be it from meat or byproducts of the animal, the latter being more problematic as the excess
nutrients will lead to eutrophication which can eventually causing hypoxia in the water body. In a similar
vein, agricultural runoff often caries excess fertilizer which also will cause eutrophicafion in streams with
its cascading effects. Within the Catawba River Basin roughly 46 streams are/were impacted by fecal
coliform, with 10 being listed on the 303(d) list. As this is a non -point source pollutant it is hard to locate
the exact source of this runoff. By general statute, the Town of Granite Falls is restricted in regulating
agricultural uses in their ETJ through the bona fide farm exemption. Roughly 20% of land use within the
basin is agricultural.
Underground storage tanks: Storage devices installed below ground that contain hazardous
materials/waste.
These tanks can contain gasoline, fuels such as propane, industrial chemicals/oils, and most often human
waste in areas not directly connected to the sanitary sewer. Any underground storage tank must be well
maintained/monitored, and correctly installed due to the risk of them leaking. The leaks can cause
whatever chemical the tank is storing to leak into the ground, harming the soil, groundwater/water table,
and even surface waters as they are being fed from groundwater. If a fuel or industrial chemical tank is
leaking, the chemical will leach into the soil — leading to toxic soil, contaminated groundwater, and
possibly impairing a stream/water body. If a septic tank is leaking, it can overwhelm the natural processes
of the soil (infiltration) leading to nutrient overload in streams fed by groundwater, or allowing pathogens
to enter, increasing the risk of disease. The 10 303(d) fecal coliform impaired streams fisted can have
some attribution to septic tank leakage.
Illicit discharges: Originate from a variety of sources, with an equally varied number of effects
dependent on the chemical that is released.
FINALNCS000602 SWMP
Town of Granite Falls
Aprl 15, 2021
Page 10
Typically, illicit discharges come from businesses, residents or municipal facilities who dump chemicals
into storm drains either incidentally due to a lack of IDDE education or general carelessness. These
chemicals can vary greatly, and can include grease, oils, chemicals, cleaning solutions, paints, metals, etc.
This is a recognized problem as we have several 303(d) streams impaired from causes related to
substances or attributions given to unclean discharges into the streams - in addition to reports generated
by the municipality. Many of the 303(d) benthos impaired streams can be attributed to IDDE issues, but
they are often from inexact/non-point sources that are attributed to illicit discharges
Illegal dumping: When residents, businesses, or municipal employees dump waste randomly in
non -permitted dumping areas.
This waste can widely vary, causing a variety of problems. For examp]e, citizens dumping televisions on
the side of the road to avoid dumping fees, which allows for the metals or chemicals inside the tv to leach
out as stormwater passes it (mercury, lead, and other metals). It can be a case of businesses dumping
waste in watershed areas where runoff passes through the waste, either carrying it, or residuals of the
waste into water bodies. It can also be a case of graders dumping sediment into areas without the correct
allowances/precautions. The debris and chemicals accumulate over time and lead to chemical
impairments, pH issues, turbidity impairments, or debris entering the stream/MS4 system.
Improper disposal of waste:
Improper disposal of waste is problematic because it allows chemicals, or difficult to manage waste, to
enter the environment in ways that may be hard to track. For example; not giving a car battery to the
correct waste management facility can allow for battery acid and lead to enter the soil which
drains/collects in the groundwater. This problem has been noticed by municipal waste managers and is
difficult to track as often the improper disposal waste is mixed in with the standard refuse. Other
examples include grease going down sinks clogging MS4 systems, chemicals from batteries leaching into
the groundwater, oil from oil changes not going to the correct facility, etc.

4.2 Program Funding and Budget
In accordance with the issued permit, the Town of Granite Falls shall maintain adequate funding and
staffing to implement and manage the provisions of the SWMP and comply with the requirements of the
NPDES MS4 Permit. The budget includes the permit administering and compliance fee, which is billed
by the Division annually. Due to the increase NPDES permit mandates, the first year of the permit cycle
will be used to determine a base line for the stormwater program funding needs. The funding mechanism
will be analyzed through the completion of a fiscal gap analysis to determine how the stormwater
program will be implemented and funding obtained.
The Town of Granite Falls, has atwo-year contract (which will need to be modified, adopted, and signed
every two years) with Western Piedmont Council of Governments for the following services: Public
Education and Outreach Program, Public Involvement and Participation Program, Illicit Discharge
Detection and Elimination Program, Post -Construction Site Runoff Control Program, and Pollution
Prevention and Good Housekeeping Programs. The current contract amount for the 2-year period (years I
and 2 of the NPDES permit cycle) is $ 35,685.00. The Town will be responsible for the cost of the annual
NPDES permit renewal, which is to be paid to the state. Any fees charged to the development community
for BMP Inspections, Plan Review, and other associated fees will help offset cost. The Town may
determine that stormwater utility fees should be implemented; these fees would be collected by the Town
through tax or utility bills. The goal would be for the funds collected to support the stormwater program
through mapping outfalls, steam repairs, and other water quality efforts. Revenue versus funding will be
reviewed each year to determine needed changes.
Should the Town of Granite Falls choose not to renew the existing two-year contract, prior to the last
month, a revision to the existing NPDES permit and Stonnwater Management Plan would need to occur.
The Town of Granite Falls would be required to renew the two-year contract, in years 2023 and 2025, to
fully carry out the 5 year NPDES permit cycle. The Town of Granite Falls would be required to fully
carry out the 5 year NPDES permit cycle.
A.3 Shared Responsibility
Beginning July 2019, the Town of Granite Falls shares the responsibility, with WPCOG (referred to as
entity), to implement the following minimum control measures, which are as stringent as the
corresponding NPDES MS4 Permit requirement. The Town of Granite Falls remains responsible for
compliance if the other entity fails to perform the permit obligation and may be subject to enforcement

Stormwater Plan Modifications and II.A.7 Written Procedures; the Town has not evaluated the
performance and effectiveness of the program and had not develop any procedures for doing so. In order
to meet the State requirements for this section, a self -assessment and the effectiveness of the program
components will be completed annually. Written procedures, otherwise known as, Stormwater
Management Plan: SWMP, has been drafted, but not adopted at this time. The SWMP will be adopted
during Permit Year One of the NPDES permit cycle following the acceptance of the SWMP and issuance
of the NPDES permit.
MS4 Inspection Report for the Town of Granite Falls - Program Implementation, Documentation &
Assessment, Permit Citation - III.A. Program Documentation; The City of Lenoir on the Town's behalf
maintained some documentation regarding illicit discharge complaints and enforcement actions; however,
there was an overall lack of documentation relating to the Town's stornwater program (e.g., no
documentation for inspections, maintenance activities, or educational programs).
MS4 Inspection Report for the Town of Granite Falls - Program Implementation, Documentation &
Assessment, Permit Citation - III.B. Annual Report Submittal The latest MS4 annual report submitted
was for the 2014-2015 reporting year. The report included a brief description of the six nummum control
measures and initiative at the time. However, the report lacked detail regarding specific milestones for
the measures, overall plan accountability, or what was accomplished during the reporting period. Instead,
the report described plans for future MS4 program implementation, which largely had not yet been
implemented. Further, the 2014-2015 report did not include a fiscal analysis (Permit Citation - IV.B).
The Town of Granite Falls will manage and report the following Best Management Practices (BMPs) for
the administration of the Stormwater Management Program using Public Education & Outreach, Public
Involvement & Participation, Illicit Discharge Detection & Elimination, Post -Construction Site Runoff
Control, and Pollution Prevention & Good Housekeeping.

PART 7: LLLICIT DISCHARGE DETECTION AND ELIMINATION PROGRAM
MS4 Inspection Report for the Town of Granite Falls — Illicit Discharge Detection and Elimination
(IDDE), Permit Citation ILD.2.a. IDDE Program: The Town had not developed written procedures for
implementing an IDDE Program. In response the Town will locate priority areas likely to have illicit
discharges, conduct routine dry weather outfall inspections, identify illicit discharges and trace sources,
elhnmate the source(s) of an illicit discharge, and evaluate and assess the IDDE Program.
The Town will also, in responses to, MS4 hispection Report for the Town of Granite Falls — Illicit
Discharge Detection and Elimination (IDDE), Permit Citation ILD.2.b. Legal Authority, the Town has
adopted and will continue to maintain and enforce the Phase II Grarite Falls Stormwater Ordinance and
other regulatory mechanisms that provide the legal authority to prohibit illicit connections and discharges
to the MS4.
The City of Lenoir provided a map of the Town of Granite Falls outfalls and MSC locations during the
MS4 Inspection; however the map was developed in 2013, the accuracy of the map is in question and the
Town did not use the map to facilitate any MS4 activities (II.D.2.c. Storm Sewer System Map). In the
future the Town will be mapping the complete MS4 within Permit Years 3 through 5 (Permit Ref: 3.4.1
BMP 20)
In the last permit cycle, the Town did not conduct dry weather screening or maintain written procedures
for dry weather field activity (ILD.2.d. Dry Weather Flow Program). Within the Stormwater
Management Plan a schedule is to be created to conduct dry weather screening quarterly. Data such as
date screening occurred, location of inspected outfall, and photos of outfall will be recorded in GIS.
The Town of Lenoir, on behalf of the Town of Granite Falls, in the past has taken a reactive approach to
Ilficit Discharge investigations with no written procedures (II.D.2.e.). A list of violators were provided to
DEQ dating back to 2011; however a majority of the cases did not have a documented resolution
(II.D.2.f.). It is unclear if any of the violations were in the Town of Granite Falls. Within the new permit
cycle, as stated below, the Town will be adopting an IIDE Plan to establish written procedures. A
proactive stance will be initiated with the use of a GIS application to track and document IDDE cases.
This will allow the Town to identify priority areas based on historical data.
Further, the Town will train municipal staff and the general public to identify illicit discharge and illegal
dumping through the use of educational outreach materials and training opportunities. Previously, no
training had been administered (ILD.2.g. & h.). Educational material will be available to help educate
public employees, businesses, and the general public about hazards associated with illicit discharges and
the improper disposal of waste.
Public complaints of any kind could be submitted to the Town through a webpage portal or by phone;
however the line of communication was not publicized (ILD.2.i). The stormwater hotline phone number,
Ls mentioned in the public education and outreach and Illicit discharge areas of this plan, will be
established on the WPCOG website. A fink from the Town's website will lead to the WPCOG portal. A
citizen can make a complaint via hotline number or through an email tool on the WPCOG webpage.
The Town of Granite Falls will develop, manage, implement, document, report and enforce an Illicit
Discharge Detection and Elimination Program which shall, at a minimum, include the following illicit
discharge detection and elimination BMPs.

PART 8: CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
hi accordance with I SA NCAC 02H .0153, the Town of Granite Falls relies upon the No Carolina
Sedimentation Pollution Control Act (SPCA) of 1973 as a qualifying alternative program to meet a
portion of the NPDES MS4 Permit requirements for construction site runoff control measures. The
SPCA requirements include reducing pollutants in stormwater runoff from construction activities that
result in land disturbance of greater than or equal to one acre, and includes any construction activity that
s part of a larger common plan of development that would disturb one acre or more. The state SPCA
Program is either delegated to a city/town, delegated to a county, or implemented by NCDEQ in non -

PART 9: POST -CONSTRUCTION SITE RUNOFF CONTROL PROGRAM
MS4 Inspection Report for the Town of Gran to Falls — Post -construction Site Runoff Control Program
Implementation Status, Permit Citation: II.F.2.a. Legal Authority, "At the time of inspection, the Town
was utilizing a Caldwell County ordinance to implement the post -construction site runoff controls
program. The Ordinance authorized Caldwell County, rather than the Town of Granite Falls, to review
plans, request information, and enter private property to conduct inspections of post -construction
controls." The Town of Granite Falls has developed and adopted a Phase II stormwater ordinance to
correct this issue. The Town of Granite Falls Phase II Stormwater ordinance includes enabling language
granting the Town of Granite Falls the ability to require deed restrictions and protective covenants
(II.F.2.e.).
Contracting WPCOG, an inventory of projects will be established (BMP 36.B.1, 2, and 3) within the
municipal limits, this is in response to Permit Citation ILR2.d. of the latest audit (2018). Along with the
nventory list proactive inspections will be administered by Staff semi-annually and certified by a private
engineer annually to ensure SCM functionality (II.F.2.g.) Upon non-compliance, enforcement action will
be taken, not a common practice in years past, but now the Town will have a GIS tracking mechanism to
proactively enforce to obtain compliance (II.F.2.i.).
MS4 Inspection Report for the Town of Granite Falls — Post -construction Site Runoff Control Program
Implementation Status, Permit Citation: II.17.3.c. Nutrient Sensitive Waters: The City of Lenoir, on behalf
of the Town of Granite Falls had not designed or constructed any SCMs in the permitted area specifically
to reduce nutrient loads. At this time it is unclear if the co-permitees within the MS4 are receiving
discharge into the nutrient sensitive waters.
This S WMP identifies the minimum elements to develop, implement and enforce a program to address
stormwater runoff from new development and redevelopment projects that disturb greater than or equal to
one acre, including projects less than one acre that are part of a larger common plan of development or
sale, that are located within the Town of Granite Falls and discharge into the MS4. These elements are
designed to minimize water quality impacts utilizing a combination of structural Stormwater Control
Measures (SCMs) and/or non-structural BMPs appropriate for the community, and ensure adequate long-
term operation and maintenance of SCMs.
In accordance with 15A NCAC 02H .0153 and .1017, the Town of Granite Falls implements the
following State post -construction program requirements, which satisfy the NPDES Phase 11 MS4 post -
construction site runoff control requirements as Qualifying Alternative Program(s) (QAPs) in the Town of
Granite Falls(s) where they are implemented.

PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS
This SWMP provides a comprehensive pollution prevention and good bousekeeping strategy for the
Town of Granite Falls municipal facilities and operations. Pollution prevention and good housekeeping is
accomplished through the implementation of seven required programs, which collectively address the
ultimate goal of preventing or reducing pollutant runoff from municipal operations such as park and open
space maintenance, fleet and building maintenance, new construction and land disturbances, and
municipal storm sewer system maintenance.
Pollution prevention and good housekeeping for municipal operations includes the following programs:
1. Muticipal Facilities Operation and Maintenance Program
2. Spill Response Program
3. MS4 Operation and Maintenance Program
4. Municipal SCM Operation and Maintenance Program
5. Pesticide, Herbicide and Fertilizer Management Program
6. Vehicle and Equipment Cleaning Program
7. Pavement Management Program
The Town of Granite Falls will manage, implement and report the pollution prevention and good
housekeeping BMPs as specified in Table 21 below for each required program. In response to the
nefficiencies identified in the MS4 Inspection Report, Permit Citations II.G.2.a, the Town had
maintained an inventory of municipal facilities, but had not determined which facilities were at risk to
generate polluted stormwater runoff. A list of these possible polluters will be established.
An O & M program for the facilities and SCMs has not be created to date (ILG.2.b. and ILG.2.e.). After
the acceptance of the SWMP and in Permit Year One, an O & M program will be established. (BMP 45).
Furthermore, the mun cipal facilities and SCMs were not being inspected annually, as required per DEQ
(II.G.2.b. c. & g.). Municipal SCMs were not inventoried to date; but "it is believed that the Town of
Granite Falls does not have municipally owned structural stormwater controls" (ILG.2.f.) Incorporated in
the O & M program, staff will be trained to determine appropriate operations and maintenance for
facilities and SCMs. To date staff had no training in this area. The Town of Granite Falls staff did not
perform street maintenance, including cleaning of catch basins and stormwater conveyances (H.G.2.e).
II.G.2.d states that "The City of Lenoir did not evaluate BMPs based on then pollutant removal" in
reference to streets, roads, and public parking lot maintenance. Several of the BMPs below address this
issue by developing, adopting, and maintaining procedures that focus on pollutant removal in these
mpervious areas. Permit Reference: 3.7.7, BMP's 59-62 address this prior lack of evaluation and
program implementation. BMP 59 focuses on setting schedules and requirements for street/parking lot
sweeping. BMPs 60 and BMP 61 focuses on minimizing and collecting fitter/debris, with BMP 60.13.2
working in part as a community outreach program. BMP 62 addresses procedures for cleaning the oils,
fluids, and debris that can come from car accidents by utilizing the developed standard spill procedures as
necessary according to H.G.2.c.
FINALNCS000602 SWMP
Town of Granite Falls
April 15, 2021
Page 58
In the audit, II.G.2.e addresses the prior lack of maintenance of the Town storm sewer system, Permit
Reference, 3.7.3. BMP's 49-52 focus on the training, inspection, and maintenance of said system. BMP
49 develops the required O&M plan which defines procedures/schedules, BMP 50 trains maintainers on
the correct procedure, BMP 51 focuses on inspection along with its documentation, and BMP 52
addresses the audit problem itself by performing the maintenance on the system with documentation.
Previously, the use of pesticides, herbicides, and fertilizers in municipal facilities was not well tracked or
managed as stated in II.G.2.h. Permit Reference, 3.7.5, BMP 55 focuses to ensure all staff using
pesticides, herbicides, and fertilizers are officially certified and following appropriate (minimal) usage.
BMP 56 focuses on tracking contractor certification as well as the copies of permits of both municipal
staff and contractors.
lLG.2.i addresses inconstant/lacking training for municipal employees in regards to good housekeeping
and pollution practices. This is addressed in: 47.B.5, 48.13.4, 50.13.1 BMP 54.B.5, 55.13.1, 57.13.2, 58.b.3,
62.b.1, and 46.b.1. Each of these BMPs focusing on each of the 7 programs required by the pennit.
II.G.2.J addresses a lack of measures regarding correct waste disposal and cleaning of municipal
vehicles/equipment. BMP 57 focuses on the washing side of the problem, addressing training, protocol,
requirements, and options for municipal vehicle operators. BMP 58 focuses on the other side of the issue,
ensuring that vehicle maintenance facilities are correctly disposing of waste and that permitting is
correctly followed to ensure MS4 compliance.
