VISUAL MONITORING SUMMARY

ATTACHMENT C
LUMBERTON ENERGY, LLC; NPDES PERMIT NO. NCS000349
VISUAL MONITORING SUMMARY
Lumberton Energy, LLC (LENC) is not currently operating and has not operated since 2009.
LENC has discharged stormwater one time in the past year. The stormwater observations
during this qualifying event identified there had been no industrial activity occurring in the area
of discharge. The stormwater discharge did not have any color, odor, foam, sheen or evidence
of erosion or deposition at the outfall. The stormwater discharge was clear with a small* amount
of floating solids and suspended solids.
*Small—floating solids and suspended solids were rated 2 on a scale of 1-5, where 1 is none
and 5 is extremely muddy/covering in floating solids.

BEST MANAGEMENT PRACTICES

ATTACHMENT D
LUMBERTON ENERGY, LLC: NPDES PERMIT NO. NCS000349
BEST MANAGEMENT PRACTICES
BEST MANAGEMENT PRACTICES AS IDENTIFIEDIN SWPPP ISSUSED MARCH 2O10:
This section contains a description of the Best Management Practices (BMPs to stabilize the
site and maintain stormwater runoff controls. Based upon an assessment of the Lumberton
Energy facility potential for contaminating stormwater runoff due to material exposure, the
following sections describe best management practices (BMPs), both structural and
nonstructural, which are in place to confirm that the potential for contamination is minimized.
Technical and Economic Feasibility Evaluation
This section evaluates the technical and economic feasibility of changing the methods and/or
storage practices at the facility to eliminate or reduce exposure of materials and processes to
stormwater.
The facility currently has minimal areas that have the potential to pollute stormwater, as
described in Sections 4.2 and 4.3. The BMPs identified in the following sections are sufficient to
control potential stormwater pollution. Additional control in these areas is not warranted due to
the structural and non-structural BMPs currently employed at the facility.
The stormwater is precluded from exposure in the Diesel Fuel Storage Tanks, as there is
secondary containment and staff will observe the presence of oils or sheens before discharge of
accumulated precipitation. The secondary containment drains are not directly connected to
stormwater conveyance systems, so locks on discharge valves are not required. Unloading
Areas have flows directed to the Wastewater Basin or other Stormwater Discharge Outlets.
Minor spills are operationally addressed rapidly to prevent spilled materials from contacting
stormwater. The Solid Fuel Yard has silt fences, and stormwater is directed to the Wastewater
Basins, so containment or covering this area is not needed, nor is practical.
Due to the site operations and construction details of the facility where elimination of exposure
is not possible, diverting stormwater away from areas of potential contamination is not practical.
Good Housekeeping
Good housekeeping maintenance of the facility is the responsibility of all plant personnel. Good
housekeeping procedures implemented at the Lumberton Energy facility include the following:
• General policing of plant grounds and equipment areas to maintain a safe and trash-free
environment.

• Routine inspections of exposed plant equipment for leaks or conditions that could lead to
discharges of chemicals or petroleum products.
• Proper inventory control procedures to insure that stored chemical and petroleum
products are maintained at the minimum level necessary.
• Proper operation and maintenance of exposed plant equipment to prevent impacts to
receiving water (see Section 5.3 on preventive maintenance).
• Properly store material and products to confirm that these items minimize potential for
receiving water impact. These materials and products must be stored in containers
adequate for the locations, such that corrosion and deterioration of the containers is
minimized. This also includes proper labeling of all containers and maintenance of
MSDS for materials stored. These procedures are addressed fully in the Lumberton
Energy Hazard Communication Plan.
Preventive Maintenance/Visual Inspection
The Lumberton Energy facility has a comprehensive preventive maintenance program for all
systems and equipment on the plant site. This program consists of regular checks and
inspections, routine lubrication, and vibration monitoring and analysis. The responsibility for
implementing various aspects of the program falls directly to the Environmental, Health, and
Safety ("EHS") Coordinator. The EHS Coordinator reports to the Facility Manager, who is
ultimately responsible for plant performance. The program includes monthly, semi-annual, and
annual checks and inspections for the equipment used at the site, including equipment and
materials storage areas that have the potential to contaminate stormwater. In particular, the
following items are to be included in routine inspections: pipes, pumps, storage tanks, pressure
vessels, pressure release valves, material storage and handling equipment, secondary
containment, catch basins, storm sewers, and the Oil/Water Separator.
The inspections include examinations for leaks, corrosion, support or foundation failure, or other
forms of deterioration or leaks. Particular attention is placed on inspecting storage containers
and secondary containment for signs of deterioration or leaks. The preventive maintenance
program also includes maintenance of a spare parts inventory, and a records system for
documentation of tests and inspections, clearance procedures, and corrective actions.
Deficiencies are noted on the forms in the Appendices and are used to generate work orders
that are processed through the Environmental, Health and Safety ("EHS") Coordinator.
Since visual inspections are a constant part of the facility preventive maintenance program, no
specific record of each inspection will be recorded in this SWPPP. Incident reports generated
which have the potential to contaminate stormwater runoff will be documented in Appendix B.
These incidents may include corroded drums, drums without plugs, corroded/damaged/leaking
tanks, tank support, tank drain valves, corroded or leaking pipes or valves, leaking pumps,
broken or cracked secondary containment, and similar items.
Since this facility is required to report under EPCRA, Section 313 by virtue of it's SIC code
(4911 and NAICS code 22112), additional preventive maintenance inspection requirements are

applicable. Water Priority Chemicals at this facility may include chlorine, ethylene glycol, and
sulfuric acid. This facility has additional requirements for facilities subject to reporting under
EPCRA, section 313, for Water Priority Chemicals, as follows:
• The team must design ate a person who will be accountable for spill prevention at the
facility and identify this person in the plan.
• The designated person is responsible for setting up necessary spill emergency
procedures and reporting requirements to isolate, contain, and clean up spills and
emergency releases of Section 313 water priority chemicals.
The list of hundreds of water priority chemicals can be found at:
httpalwww.d nrec.state.de.us/water2000/Sections/SurfVVater/Library/APPEN DIXA.pdf
Spill Prevention and Response
Subject to the Oil Pollution Act of 1990, the Lumberton Energy facility has in place and
maintains a Spill Prevention Control and Countermeasures Plan, or SPCC plan, to address
planning, response, and mitigation procedures in the event of a petroleum product spill. Under
this plan, the EHS Coordinator is the primary spill response coordinator. The Facility Manager is
the secondary spill response coordinator. Included in this plan are an identification of potential
oil sources and spill areas, records of past spill events, emergency contacts and telephone
numbers, documentation procedures, and requirements for training.
The Emergency Response Plan, Hazard Communication Plan, and Lab Safety Plan addresses
spill response procedures for chemicals stored at the facility that could be exposed to
stormwater (acid, caustic, cooling tower treatment chemicals). This includes maintenance of
adequate safety equipment, such as respirators, eye guards, protective clothing, fire
extinguishers, or other items. Spill prevention is provided through a combination of employee
training, maintenance of primary and secondary containment, and visual inspections. In
addition, materials handling and storage procedures in place are integral to a spill prevention
plan. These include labeling of storage containers, maintenance of MSDS(s), placarding of
materials storage areas, and similar requirements.
Particular attention should be placed on minimizing ash spills and dusting in the vicinity of the
ash silos. This will be done through training employees in the proper procedures for unloading
ash, including the dust suppression system, and good housekeeping around the ash silo areas.
Spills which have contaminated, or have the potential to contaminate, stormwater runoff will be
documented and reported on forms in Appendix B. The SPCC Plan Appendix D and Appendix E
contain a Storage Tank Inspection Form and an Initial Notification Form, respectively. The Initial
Notification Form includes the date and time of incident, weather conditions, duration, cause,
environmental problems, response procedures, parties notified, recommended revisions of the
BMP program, operating procedures, and equipment needed to prevent recurrence.
