2.1 Spills

Spill protection is required of the contractor. The contractor shall carry spill supplies such as absorbent material capable of emergency cleanup of spills or drips. In the event of a spill, the contractor shall notify the Contracting Officer’s Representative (COR) as soon as it is safe to do so.

3.0 Specific Tasks and Performance Requirements

3.1 Pre-Cleaning Sampling and Testing

Prior to any cleaning and pumping operations, the contractor shall perform appropriate tests of the OWS contents (including floating materials, liquids, and sludge) to determine if the materials meet the criteria for hazardous waste.

• Hazardous Contingency: If tests indicate the presence of hazardous materials, the contractor shall immediately terminate servicing and contact the COR and the installation environmental office. The environmental office will determine the subsequent requirements for the disposal of hazardous contents.

3.2 Pumping, Evacuation, and Packaging

If the contents are confirmed as non-hazardous, the contractor shall proceed with the cleaning operations. The contractor shall pump all oil, oil residue, sludge, and other waste from both 10,000-gallon separators, draining them completely.

• Discharge Prohibition: In accordance with DAFMAN 32-7002 and related local supplements, the contractor shall not discharge any OWS residue, wash water, or industrial waste to the environment, sanitary sewer, or stormwater sewer systems under any circumstances without explicit written approval from the Installation Environmental Office.

• The contractor shall be responsible for the safe transport and legal disposal of all pump-out waste (oil, water, and sludge). Disposal must occur at an approved off-base facility in accordance with environmental regulations.

3.3 Cleaning Procedures

The contractor shall thoroughly wash and clean the interior of the separators. Any reusable coalescing media or internal filters must be carefully removed, cleaned, and fully dried before reinstallation. All secondary wash water generated during this process must be captured, containerized, and managed in accordance with all relevant regulations.

3.4 API 421 Inspection Protocol

While the separators are empty and clean, the contractor shall conduct a comprehensive inspection in accordance with API Publication 421. The inspection protocol must include:

• Structural Integrity: Inspection of the vault bottom and walls for cracks, leaks, corrosion, and overall structural degradation.

• Internal Components: Checking the condition and alignment of coalescing plate packs, baffles, and skimmer mechanisms.

• Seals and Gaskets: Inspecting all access ports, hatches, and pump seals for degrading gaskets.

• Plumbing and Valves: Inspecting associated transfer pumps, effluent pumps, and non-return (check) valves.

3.5 System Restoration

Following the washing and inspection phase, the contractor shall refill the separators with clear water to re-establish the proper operational seal, ensuring no residue is flushed into the discharge line during restart.

3.6 Hazardous Waste Tracking and Disposal (DAFMAN 32-7002 Compliance) In the event that the waste material is hazardous, the contractor shall utilize a certified hazardous waste transporter to safely remove the containerized waste from the installation.

• Tracking/Manifesting: The contractor must prepare the EPA Uniform Hazardous Waste Manifest utilizing the base's SQG EPA ID number. In no event shall the contractor sign the manifest. Only a COR with active manifest-signing certification shall sign the manifest.

• Disposal: The waste must be transported to a fully permitted Resource Conservation and Recovery Act (RCRA) Treatment, Storage, and Disposal Facility

(TSDF).

4.0 Deliverables

• 4.1 Service and API 421 Inspection Report: The contractor shall provide a written report to the Contracting Officer Representative (COR) detailing the API 421 inspection findings, the condition of the OWS units, and recommendations for future maintenance.

• 4.2 Hazardous Waste Manifests & Tracking Documents: The contractor must submit the initial signed Uniform Hazardous Waste Manifests upon departure from the base and provide the final TSDF-signed return-to-generator manifests to the base environmental office within the required timeframe for SQGs. Additionally, any waste tracking documents related to non-hazardous waste shall be submitted to the COR.

5.0 Security and Safety Requirements

• 5.1 Training Certification: In accordance with DAFMAN 32-7002, all contractor personnel handling hazardous waste must have successfully completed HW training appropriate to their job responsibilities as required by 40 CFR Part 262, Subpart A (e.g., HAZWOPER) prior to executing this work.

• 5.2 Installation Security: All contractor personnel must adhere to installation security requirements, including obtaining necessary gate passes and maintaining a safe working environment.
