1.0 INTRODUCTION

[Section V.3 of Part II]

1.1 The Stonnwater Pollution Prevention Plan (SWPPP) was prepared in accordance with the requirements specified in Section V.3 of Part II of Waterford 3 (W3)

LPDES Pennit LA0007374 for stonnwater discharges associated with industrial activity at the W3 facility.

1.2 The objectives of the SWPPP are to:

  • Identify pollution sources which may reasonably be expected to affect the quality of stonnwater discharges from the facility.
  • Describe and ensure the implementation of practices to reduce pollutants in stonnwater discharges.
  • Ensure compliance with the tenns ofW3 LPDES Pennit LA0007374.

2.0 PERMITTED OUTFALLS [Section V.2 of Part II]

2.1 All runoff leaving developed areas of the site flows into the east and west plant drainage ditches where it is sampled quarterly at Outfall 004 (common connection point for ditches) and analyzed for total organic carbon, oil & grease, TSS and pH in accordance with W3 LPDES Pennit LA0007374.

2.2 Although Outfall 004 is designated for stonnwater, this outfall also receives potable water from the tire water system, maintenance wastewaters, low volume wastewaters and previously monitored eflluents from Outfalls 204, 701, 801 and 1001.

2.3 There are fourteen pennitted LPDES outfalls at the W3 facility as shown below:

  • Outfall 001 (Once-Through Non-Contact Cooling Water)
  • Outfall 004 (Stonnwater Runotl)
  • Outfall 005 (Energy Education Center Treated Sanitary Wastewater)
  • Internal Outfall 101 (Liquid Waste Management System)
  • Internal Outfall 201 (Boron Management System)

W3SWPP (Rev. 1) - 4

  • Internal Outfall 204 (Vehicle Wash Wastewater)
  • Internal Outfall 301 (Filter Flush Water)
  • Internal Outfall 501 (Auxiliary Component Cooling Water Basin A)
  • Internal Outfall 601 (Auxiliary Component Cooling Water Basin B)
  • Internal Outfall 901 (Mobile Metal Cleaning Wastewater)
  • Internal Outfall 1001 (Miscellaneous Intermittent Wastewater) 2.4 Outtalls 701 and 80 I, which are actually located inside a plant structure, also receive limited stormwater runoff and is sampled monthly and analyzed for total suspended solids, oil & grease and pH and quarterly for TOC in accordance with W3 LPDES Permit LA0007374.

3.0 ANNUAL INSPECTION [Section V.4.a of Part II]

3.1 Chemistry is to annually:

  • Inspect areas where industrial materials or activities are exposed to storm water and areas where spills and leaks have occurred in the past three years (if applicable).
  • Evaluate whether measures to reduce pollutant loadings identified in this SWPPP are adequate and have been properly implemented in accordance with the terms of the permit or whether additional control measures are needed.

3.2 Chemistry is to specifically look for the following:

  • Industrial materials, residue or trash on the ground that could contaminate or be washed away in storm water.
  • Leaks or spills from industrial equipment, drums, barrels, tanks or similar containers.

W3SWPP (Rev. 1) - 5

  • Offsite tracking of industrial materials or sediment where vehicles enter or exit the site.
  • Tracking or blowing of raw, final or waste materials from areas of no exposure to exposed areas.
  • Evidence of or potential for pollutants entering the drainage system.
  • Stormwater best management practices (BMPs) identified in the Plan are operating correctly.
  • BMPs are effective In preventing significant impacts to receIVing waters where discharge locations or points are accessible. Where discharge locations are inaccessible, nearby downstream locations are inspected, if possible.

3.3 Chemistry is to prepare a summary report of the inspection results utilizing the information and inspection form shown in Attachment 1 (Annual Stormwater Inspection Report) or similar.

4.0 POTENTIAL POLLUTANT SOURCES [Section V.4.b of Part II]

4.1 Site Map A. As allowed in Section V.3 of Part 11 of the W3 LPDES Permit LA0007374, the site is incorporating by reference the following portions of the W3 SPCC Plan to satisty the site map requirement that identifies areas where stormwater may contact potential pollutants or substances that can cause pollution:

  • Figure 2 (W3 Facility Layout) identifies stormwater drainage pathways for the site.
  • Figures 3 (Oil & Gasoline Product Locations) and 4 (Transformer Locations) include potential pollutant sources related to petroleum products.

In addition, Tables 1 (Oil and Gasoline Product Locations) and 2 (Transformer Locations), which are keyed to Figures 3 and 4, includes the type of petroleum product, location, quantity and predicted direction of W3SWPP (Rev. 1) - 6

flow. For quick reference, sources that come in contact with stormwater are shown in Table I (Petroleum Related Potential Pollutant Sources) of this SWPPP.

B. Other sources that come in contact with stormwater are listed in Table 2 (Non-Petroleum Related Potential Pollutant Sources) and Figure I (Non-Petroleum Related Potential Pollutant Sources) of this SWPPP.

4.2 Reportable Leaks or Spills A. From 2003 through 2005, there has been one spill of a hazardous material that was required to be reported under CERCLA as discussed below.

  • On October 22, 2003, -55 gallons of iron solvent, which also contained hydrazine, leaked from a valve outside of a containment berm onto the asphalt located on the northwest side of the Fuel Handling Building. Of the 55 gallons, hydrazine constituted approximately 4 pounds. A small amount of chemical solution also entered a storm drain but was limited to and did not travel beyond the first catch basin. Free standing chemical solution was vacuumed and wiped up with absorbent materials, and the chemical solution was removed from the catch basin with a vacuum truck.

The spilled was contained within the facility property boundary. [CR-WF3-2003-03022] There is no chemical residual remaining from this event which would contribute pollutants to stormwater runoff.

B. There have not been any spills or leaks of toxic or hazardous pollutants that have been required to be reported under CERCLA or the Clean Water Act since October 22, 2003.

C. Should a "reportable spill" occur, this section of the Plan would be updated to include such information as specified in Section V.4.b of Part II of W3 LPDES Permit LA0007374.

D. Although there have been minor spills or leaks that have occurred at the W3 site that were not required to be reported, it was concluded that these did not "significantly" affect stormwater runoff or the environment.

W3SWPP (Rev. 1) - 7

4.3 Potential Pollutant Sources A. Storage and Use of Water Treatment Chemicals

  • Water treatment chemicals are stored in bins and drums inside a covered building with secondary containment. These bins and drums are sealed unless in use and within enclosed buildings during use. In the event of a leak or spill, material would flow to a sump where it would then be treated and discharged in accordance with W3 LPDES Permit LA0007374. Therefore, exposure of pollutants to stormwater is unlikely.

B. Aboveground Oil & Gasoline Storage Tanks & Containers

  • Aboveground oil & gasoline storage containers are either within secondary containment structures or within enclosed buildings as described in Table I (Oil and Gasoline Product Locations) of the W3 spec Plan. For tanks located within enclosed buildings, exposure of pollutants to stormwater is unlikely.
  • For tanks within secondary containment structures that are exposed to rainfall as described in Table 1 (Oil and Gasoline Product Locations) of the W3 spec Plan, drainage from these areas either flow through the Yard Oil Separator (Outfall 1001) or is checked prior to drainage to ensure water quality standards are met as discussed in the Section 4.12 (F acility Drainage) of the W3 spec Plan. Existing best management practices at these areas to minimize contribution to pollutants in storm water runoff are identified in Table I (Petroleum Related Potential Pollutant Sources) of this SWPPP.

C. Underground Diesel Fuel Oil Storage Tank

  • There is one underground storage tank located at the W3 facility. Since this tank is underground, exposure to stormwater is unlikely.

W3SWPP (Rev. 1) - 8

D. Transformers

  • Transformers are within secondary containment structures as described in Table 2 (Transformer Locations) of the W3 SPCC Plan. Secondary containment drainage from these areas either flow through the Yard Oil Separator (Outfall 00 I) or is checked prior to drainage (for tanks exposed to rainfall) to ensure water quality standards are met as discussed in the Section 4.12 (Facility Drainage) of the W3 SPCC Plan. Existing best management practices at these areas to minimize contribution to pollutants in stormwater runoff are identified in Table I (Petroleum Related Potential Pollutant Sources) of this SWPPP.

E. Fuel Unloading Areas (Oil & Gasoline)

  • Fuel unloading areas are identified in Table I (Petroleum Related Potential Pollutant Sources) of this SWPPP and are also shown in Table I (Oil and Gasoline Product Locations) and Figure 3 (Oil & Gasoline Product Locations) of the W3 SPCC Plan. Since fueling activities are associated with these areas, minor spills could occur resulting in potential stormwater runoff contaminated with petroleum hydrocarbons.
  • Runoff from these areas either drains to the east or west drainage ditches, which are equipped with weirs, prior to discharge into the 40 Arpent Canal via LPDES Outfall 004 (Stormwater).
  • As discussed in Section 4.2.C of the W3 SPCC Plan, proper discharge prevention measures are taken such as placement of absorbent booms around tank truck and plant fill connections, placement of drip pans under truck valve station, proper connecting and disconnecting of fill pipe, verification of no leakage from any hoses or connections prior to tank truck departure and removal of product from the unloading pad.

Therefore, potential stormwater contamination due to petroleum hydrocarbons is minimized.

W3SWPP (Rev. 1) - 9

  • In the event of a spill, response and reporting measures would be conducted in accordance with W3 Procedure UNT-007-064, "Hazardous Material Emergency Response Plan" which specifies response and cleanup measures, along with reporting measures to offsite regulatory agencies.
  • Existing best management practices at these areas to mmlmlze contribution to pollutants in stormwater runoff are identified in Table I (Petroleum Related Potential Pollutant Sources) of this SWPPP.

F. Sandblast Area

  • The sandblast area is identified in Figure I (Non-Petroleum Related Potential Pollutant Sources) of this SWPPP. Since sandblasting activities occur at this area, stormwater runoff could potentially be contaminated with suspended solids and metals.
  • Runoff from this area either drains to the east or west drainage ditches prior to discharge into the 40 Arpent Canal via LPDES Outfall 004 (Stormwater).
  • To minimize potential storm water contamination due to suspended solids and metals at this area, spent sandblast material is periodically removed from the grounds and disposed of off-site. Existing best management practices at these areas to minimize contribution to pollutants in stormwater runoff are identified in Table 2 (Non-Petroleum Related Potential Pollutant Sources) of this SWPPP.

G. Laydown Areas

  • Laydown areas are identified in Figure 1 (Non-Petroleum Related Potential Pollutant Sources) of this SWPPP. Materials stored in these areas include metal, wood, storage sheds, concrete blocks and other equipment.
  • Runoff from this area drains to either the east or west drainage ditches prior to discharge into the 40 Arpent Canal via LPDES Outfall 004 (Stormwater).

Pollutants of concern at this location include suspended solids and metals.

W3SWPP (Rev. 1) - 10

  • To minimize potential stormwater contamination due to suspended solids and metals, the housekeeping practices identified in W3 Procedure UNT-007 -006 (Housekeeping) are implemented at these areas. In addition, this area is also periodically inspected during plant rounds. Existing best management practices at these areas to minimize contribution to pollutants in stormwater runoff are identified in Table 2 (Non-Petroleum Related Potential Pollutant Sources) of this SWPPP.

H. Herbicide Usage

  • Herbicides (Roundup) are applied by a license contractor to fence lines and equipment pads on an as-needed basis. Material management practices designed to minimize over use of herbicides includes (I) observing safety and environmental procedures when applying chemicals to areas of the facility and (2) establishing integrated herbicide management controls conducted under the supervision of a licensed applicator. These chemicals are not directly applied to water or to areas where surface water is present.

Equipment used to apply herbicides is managed offsite by contract personnel. There is low reasonable potential for storm water contamination because herbicides are only used by a licensed applicator and are not applied when a storm event is expected to occur within one hour.

I. Miscellaneous Areas

  • Miscellaneous areas may be temporarily established on-site for plant outage or other emergency support purposes. In the event that industrial activities are associated with these areas and involve areas not already covered by the W3 SWPPP, an addendum will be added to Attachment III of this Plan to ensure that appropriate storm water controls are implemented.

W3SWPP (Rev. 1) - 11

5.0 POTENTIAL EQUIPMENT FAILURES [Section V.4.C of Part II) 5.1 There has not been any site-specific or fleet-specific experience which would indicate a reasonable potential for equipment failure. However, the following information is being provided for purposes of this SWPPP:

  • Tables I (Oil and Gasoline Product Locations) and 2 (Transfonner Locations) of the W3 SPCC Plan describes the predicted direction of release and quantity of pollutants in the event of an equipment failure.
  • Figure 2 (W3 Facility Layout) of the W3 SPCC Plan identifies the direction of stormwater drainage at the site. As seen in Figure 2, stormwater runoff from the industrial portion of the site flows to the onsite east and west drainage ditches that are equipped with weirs where it is discharged into the 40 Arpent Canal via LPDES Outfall 004 (Stormwater) and sampled quarterly for total organic carbon, oil & grease, TSS, and pH prior to entering receiving waters.

5.2 It is unlikely that significant amounts of pollutants would reach surface waters due to the following best management practices currently implemented at W3:

  • As discussed in Section 4.3.E above, discharge prevention practices are in place during fuel unloading activities, and leaks or spills are promptly responded to and remediated.
  • Tanks, containers and transformers are periodically inspected for leaks or other deteriorating conditions that could result in a release in accordance with Section 4.6 (Inspections, Tests & Records) of the W3 SPCC Plan.
  • As described in Tables I (Oil and Gasoline Product Locations) and 2 (Transformer Locations) of the W3 SPCC Plan, secondary containment drainage from these areas either flow through the Yard Oil Separator or is checked prior to drainage (for tanks exposed to rainfall) to ensure water quality standards are met as discussed in the Section 4.12 (Facility Drainage) of the W3 SPCC Plan.

W3SWPP (Rev. 1) - 12

6.0 INSPECTION REPORTS 6.1 Chemistry is to maintain for three years a record summarizing the results of the inspection required in Section 3.0 above and a certification statement that the facility is in compliance with the W3 SWPPP. [Section V.4.d of Part II]

6.2 Completed annual inspection summary reports are to be attached to Attachment II (Inspection Reports) ofthis W3 SWPPP. [Section V.4.e of Part II]

6.3 W3 shall provide the Louisiana Department of Environmental Quality a copy of this SWPPP and any supporting documentation, upon request. [Section V.4.f of Part II]

7.0 BEST MANAGEMENT PRACTICES 7.1 Drainage Systems [Section V.S.a of Part II]

A. To minimize potential impacts on the site drainage systems, W3 is to:

  • Maintain adequate roads and driveway surfaces.
  • Remove debris and accumulated solids from the drainage system.
  • Clean up immediately any spill by sweeping, absorbent pads or other appropriate methods.

7.2 Spill Cleanups [Section V.S.b of Part II]

A. All spills are to be cleaned up immediately in accordance with W3 Procedure UNT-007-064 (Hazardous Materials Emergency Response Plan) and spill debris disposed of in accordance with NMM Procedure EN-EV-106 (Waste Management Program).

B. Use of detergents, emulsifiers or dispersants to clean up spills is prohibited except where:

  • Necessary to comply with state or federal safety regulations (i.e.,

requirement for non-slippery work surface).

  • The cleanup practice does not result in a discharge and does not leave residues exposed to future storm events.

W3SWPP (Rev. 1) - 13

C. For all spills, initial cleanup is to be done by physical removal with chemical usage minimized.

7.3 Storage Practices [Section V.S.c of Part II]

A. W3 is to maintain all equipment, parts, dumpsters, trash bins, petroleum products, chemical solvents, detergents or other materials exposed to storm water in a manner that prevents contamination of stormwater by pollutants.

7.4 Recycle/Disposal Practices [Section V.S.d of Part II]

A. W3 is to either recycle (where feasible) or contain for disposal waste fuel, lubricants, coolants, solvents or other fluids used in the repair or maintenance of vehicles or equipment.

B. Spills associated with these materials are to be cleaned up by dry means whenever possible.

7.5 Secondary Containment Structures [Section V.S.e of Part II]

A. Secondary containment structures for tanks exposed to rainfall at the W3 facility are impervious to contain spills and can contain the entire contents of the largest tank plus sufficient freeboard to allow for precipitation.

B. Table I (Petroleum Related Potential Pollutant Sources) of this SWPPP and also Table I (Oil and Gasoline Product Locations) and Figure 3 (Oil &

Gasoline Product Locations) of the W3 SPCC Plan identifies those tanks exposed to rainfall.

7.6 Diked Areas [Section V.S.f of Part II]

A. W3 is to ensure that diked areas surrounding storage tanks exposed to rainfall are free of residual oil or other contaminants.

B. As discussed in Section 4.8.B of the W3 SPCC Plan, valves on diked areas are securely locked in the closed position or restrained by other positive means when in non-operating or non-standby conditions.

W3SWPP (Rev. 1)* 14

7.7 Inspections [Section V.S.g of Part II]

A. As discussed in Section 4.6 (Inspections, Tests and Records) of the W3 SPCC Plan, inspections are periodically conducted on check valves, tanks, drains or other potential sources of pollutant releases.

B. As a result of these inspections and W3's corrective action process which is implemented through NMM Procedure EN-U-I02 (Corrective Action Process), check valves, tanks, drains or other potential sources of pollutant releases are being maintained to assure their proper operation and to prevent the discharge of pollutants.

7.8 Waste Management Practices [Section V.S.h of Part II]

A. W3 will comply with all applicable regulations promulgated under the Louisiana Solid Waste and Resource Recovery Law and the Hazardous Waste Management Law (L.R.S. 30:2151, etc.).

B. Management practices that W3 is required to comply with under the above regulations are captured in W3 Procedure UNT-007-064 (Hazardous Materials Emergency Response Plan) and NMM Procedure EN-EV-I06 (Waste Management Program).

W3SWPP (Rev. I) - 15

8.0 AMENDMENTS TO SWPPP 8.1 W3 is to amend this SWPPP:

A. Whenever there is a change in the facility or change in the operation of the facility which materially increases the potential for the ancillary activities to result in a discharge of significant amounts of pollutants. [Section V.S.i of Part II)

B. If the SWPPP proves to be ineffective in achieving the general objectives of preventing the release of significant amounts of pollutants to water of the state. [Section V.S.j of Part II]
