The following storage areas are located outside:
• One 15,000 -gallon hot dip storage tank is located on an asphalt -paved surface
south of the main building. The tank is provided with secondary containment in
the form of an open -top containment area concrete sump. The sump is
approximately 23.2 feet by 17.4 feet by 5 feet, which equates to an approximate

collected within the containment area is removed and disposed of in accordance
with applicable regulations.
• Two 6,000 -gallon asphalt emulsion storage tanks are located on an asphalt -paved
surface west of the Water Test building. The tanks are provided with secondary

collected within the containment area is removed and disposed of in accordance
with applicable regulations.
One fueling station with four pumps is located on an asphalt -paved surface near

Best Management Practices Summary

BMP Summary
General Practices
The facility performs inspections of all outside areas and notes any issues Thal need to
be corrected. Trash is collected in dumpsters.
Materials Storage
Charlotte Pipe encourages proper material storage to prevent the release of materials
and pollutants that may cause stormwater runoff pollution. Proper storage techniques
include:
• Store materials inside of the facility or under cover, when possible.
• Store materials so that there is adequate aisle space to facilitate material transfer
and inspections.
• When appropriate and/or otherwise required, post signs or placards on the
periphery of the storage areas to indicate the hazards associated with the
materials stored within.
• Store containers and drums away from heavy traffic routes, when possible, to
minimize accidental spills.
• Store containers according to the manufacturer's instructions to avoid damaging
the containers from improper weight distribution.
Material Inventory Control
Improved material inventory practices 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 material usage. The following material
inventory BMPs are implemented at the facility:
• Material Safety Data Sheets (MSDS) are maintained for all products used at the
facility. A MSDS is requested and maintained on file prior to the use of the
product for which it was written.
• Containers are labeled to show the name and type of substance contained
therein. When appropriate and/or otherwise required, containers will also be
labeled as to the stock numbers, hazards of the materials stored therein,
expiration date, suggestions for proper handling, and first aid information.

Equipment Operations and Maintenance
Charlotte Pipe personnel implement the following equipment operation and
maintenance BMPs as part of the facility's good housekeeping program:
• Stormwater drains are labeled to facilitate employee familiarity with drain
locations and to remind employees that non-stormwater discharges are not
allowed;
• Trash and other solid waste materials are regularly collected and disposed of
appropriately;
• Asphahed outside areas are cleaned eac1L day wily a sweeper to reirwve ally
settled particulate debris;
• Equipment is inspected for leaks or conditions, that could lead to discharges of
pollutants or contact of stormwater with raw waste materials;
• Mobile vehicles (company automobiles, forklifts, general purpose vehicles, etc.)
are maintained to prevent leaking; and
• Equipment, which is not working properly, is promptly repaired.
Structural Control Measures
Charlotte Pipe currently employs three types of structural control measures at the
facility to prevent pollutant contact with stormwater. These structural control measures
include: (1) Preventive Covering, (2) Substance Containment, and (3) Vegetative Cover.
Each of these is discussed in more detail below.
• Preventive covering comprises the physical enclosure of material, equipment, or
process operations, when feasible. Charlotte Pipe has built a 150'L x 120'W x
35'H building along the northeastern portion of our property to enclose the
aggregate waste storage areas thus reducing stormwater exposure.
Substance containment measures are used to physically contain or capture a
release of solid, liquid, or gaseous material. These containment measures
provide a second line of defense by preventing a release of material from the
primary containers to reach down gradient surface water. Containment will
prevent both run-on and run-off.

Secondary containment and spill response and prevention procedures for the
bulk liquid storage containers at the facility (i.e. the fuel and asphalt above
ground storage tanks located in Area VII) are described in detail in the Spill
Prevention Control and Countermeasures (SPCC) Plan. Charlotte Pipe also
employs secondary containment for non -petroleum based products by storing
most products used in the manufacturing process inside of the foundry buildings
or under cover and surrounding bulk material spent storage area with berms to
prevent stormwater runoff. Stormwater which accumulates in the containment
areas is at a minimum visually observed for color, foam, outfall staining, visible
sheen, and dry weather flow prior to release of the accumulated storxnwater.
Accumulated stormwater is released only if found uncontaminated by the
materials stored within the containment area.
• Vegetative cover on nota -impervious areas prevents erosion and improves the
infiltration capacity of the soil. In addition, the vegetation should be maintained
in all areas to prevent erosion. Charlotte Pipe ensures that all areas of the facility
that are not covered in buildings, concrete, asphalt, and gravel pavement, are
provided with vegetative cover.

Significant Changes in Industrial Activities

Significant Changes in Industrial Activities
Charlotte Pipe has made the following significant changes in industrial activities in the
last five (.�) years'
Replacement of the fittings emulsion asphalt dip line with an E -coat system. The
fittings emulsion asphalt dip line, which partially ran outside, was removed from
service mid -2013 and is currently in the process of being dismantled. This
modification has the potential to significantly impact stormwater as the new E -
coat system is located inside a building; thus, there is no potential stormwater
impacts associated with its operation.
• The new E -coat applied to castings is expected to be more rust -resistant than the
emulsion asphalt coating previously used; therefore, stormwater impact from
water run-off of the fittings product stored outside should be reduced.
• Installation of a 150'L x 120'W x 35'H aggregate waste storage building along the
northeastern portion of our property. This building enclosed the aggregate
waste storage areas thus eliminating stormwater exposure from waste aggregate
pile run-off.
