7 1.0 INTRODUCTION This Waste Management Plan (WMP) was specifically developed to present the waste management practices and procedures to be followed for the types and quantities of waste expected to be generated during the petroleum sites investigations. The WMP identifies waste management activities that will be conducted during the storage and preparation of waste (including waste characterization, packaging, storage, and management while in storage). Discussion of the transportation and disposition of waste materials at appropriate disposal and recycling facilities is also included. It is the responsibility of the Project Manager to verify that all project personnel are aware of the requirements stipulated in this WMP. The WMP provides information on how wastes, including potentially hazardous wastes associated with project activities, will be managed and disposed of. A secondary goal of this WMP is to ensure that waste minimization practices are followed, to a practical extent, to reduce the volume of waste that will be generated, stored, and removed from the site for disposal. The WMP is also a primary component of the Tetra Tech EC, Inc. (TtEC) Compliance Program, which includes on-site environmental compliance inspections. The WMP will be revised if either the scope of this project or the applicable regulations change. ECSD DrWMP_PetroSites_AppC.doc C.1-1 Draft Waste Management Plan

9 2.0 WASTE MANAGEMENT 2.1 PROJECT WASTE DESCRIPTIONS Field activities associated with the petroleum sites investigations will involve the generation, management, and disposal of various waste streams. Wastes that are anticipated to be generated may include, but are not limited to the following: Contaminated soil/sediment (Resource Conservation and Recovery Act [RCRA] hazardous, non-rcra hazardous, and nonhazardous waste) from sampling activities Nonhazardous solid waste, such as inert construction debris and trash Wastewater, including purge water and decontamination fluids Personal protective equipment (PPE) The following disposition options will be applied to the wastes described above: Soil intended for off-site disposal classified as a RCRA hazardous or non-rcra (California) hazardous waste will be transported to a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Off-Site Rule approved waste facility. Soil, PPE, and debris intended for off-site disposal classified as non-hazardous waste will be transported to a CERCLA Off-Site Rule approved waste facility. Wastewater will be characterized and profiled for proper off-site treatment and/or disposal through the West-Side Aquifers Treatment System (WATS). Table C.2-1 presents a matrix summarizing applicable waste characterization, containment, storage, transportation, and disposal requirements for each of the aforementioned waste streams. 2.2 WASTE CLASSIFICATION According to RCRA requirements of Title 22 California Code of Regulations (CCR), Section , waste characteristics can be measured by an available standardized test method or be reasonably classified by generators of waste based on their knowledge of the waste, provided that the waste has already been reliably tested or if there is documentation of chemicals used. A waste determined not to be a RCRA hazardous waste may still be considered a state-regulated non-rcra hazardous waste. The state is broader in scope in its RCRA program in determining hazardous waste. Title 22 CCR, Section (a)(2), lists the Total Threshold Limit Concentrations (TTLCs) and the Soluble Threshold Limit Concentrations (STLCs) for non- RCRA hazardous waste. A waste is considered hazardous if its total concentrations exceed the TTLCs or if the extract concentrations from the Waste Extraction Test (WET) exceed the ECSD DrWMP_PetroSites_AppC.doc C.2-1 Draft Waste Management Plan

10 STLCs. A WET is required when the total concentrations exceed the STLC by a factor of 10, but are less than the TTLCs. California also has additional hazardous waste classification criteria (including 96-hour fish bioassays) that may need to be considered on a case-by-case basis. Wastes determined to be hazardous wastes under California regulations and not under federal regulations are referred to as non-rcra hazardous wastes. The waste classification requirements also apply to water generated from groundwater sampling, daily decontamination activities, and waste oils and fluids (if any) generated from the on-site project equipment. Wastewater resulting from sampling and decontamination water will be collected and contained in 55-gallon drums or other appropriate containers. When the container is approximately half-full or at least every 60 days, whichever occurs first, it will be disposed of through WATS. PPE will be characterized based on generator knowledge and will be disposed of at an off-site landfill. Waste oils and fluids (if generated) will be sampled for off-site disposal. 2.3 WASTE ACCUMULATION AND STORAGE Regulations per 40 Code of Federal Regulations (CFR), Part 262, and 22 CCR, Section 66262, are applicable to the generation, storage, management, and accumulation of RCRA and non- RCRA hazardous wastes, respectively. Specific requirements apply to the accumulation time for hazardous wastes on site and to the accumulation and labeling of hazardous wastes. This project may result in the temporary accumulation of hazardous wastes. These wastes will be managed, accumulated, and inspected in accordance with the regulations Soil Hazardous and non-hazardous soil may be generated during the investigation. Soil will be stored in Department of Transportation (DOT)-approved 55-gallon drums as described in Section 4.0 of the Work Plan, and sampled and analyzed for final disposition. Soils with visible staining or odors will be segregated and stored separately. Soils will be staged at the Biopad, located on the east side of Moffett Debris Nonhazardous debris, including trash and inert construction debris such as broken up asphalt and concrete cores, may be generated during the site activities. These wastes will be stored in DOTapproved 55-gallon drums Wastewater and Waste Fluids Any wastewater generated, primarily decontamination water generated from equipment and purge water generated from groundwater sampling, will be collected in DOT-approved 55-gallon drums and labeled as Potentially Hazardous Water Pending Analysis. An accumulation start ECSD DrWMP_PetroSites_AppC.doc C.2-2 Draft Waste Management Plan

11 date will be noted on the label. Wastewater may be stored and disposed of through WATS, if applicable Used PPE Used PPE will be stored in DOT-approved 55-gallon drums within the designated hazardous waste container storage area, which will be designed and managed in accordance with the substantive requirements of the container management regulations codified in 22 CCR, Sections through CONTAINER LABELING Containers of potentially hazardous waste will be labeled, using indelible ink, with a detailed description of contents (including accumulation start date) and the words Potentially Hazardous Analysis Pending. A container log will be used to track contents, accumulation start data, sample identification number, sample date, and disposal date. If containers are determined to contain nonhazardous waste, they will be labeled accordingly. If containers are determined to contain hazardous waste, they will immediately be labeled with a completed Hazardous Waste label, which will include the following: U.S. Environmental Protection Agency (EPA) identification number of the generator Name and address of the generator EPA waste code DOT shipping name (prior to off-site shipment) Description of contents Date of generation An inventory of waste containers will be maintained. In addition, weekly inspections of container storage areas will be conducted and logged while wastes remain in these areas to ensure the integrity of the containers and secondary containment, to check for leaks or spills, and to ensure that labels and markings are in good condition. 2.5 WASTE ACCUMULATION AREAS TtEC and subcontractors working on this project will implement the following hazardous waste storage area requirements for waste stored on site: A sign with the legend, Danger Hazardous Waste Area Unauthorized Personnel Keep Out (written in English and Spanish) will be posted at each waste accumulation area in sufficient numbers to be seen from any approach. The signs will be legible from a distance of at least 25 feet. Aisle space will be maintained to allow for the unobstructed movement of personnel, fire protection equipment, spill control equipment, and decontamination equipment to ECSD DrWMP_PetroSites_AppC.doc C.2-3 Draft Waste Management Plan

12 any area of facility operation in an emergency, unless aisle space is not needed for any of these purposes. The following emergency equipment will be located or available to personnel during active waste management activities at each accumulation area: A device, such as a telephone or a hand-held two-way radio, capable of summoning emergency assistance Portable fire extinguishers, fire control equipment, spill control equipment, and decontamination equipment Water at adequate volume and pressure to supply water hose streams, or foamproducing equipment, automatic sprinklers, or water spray systems For minor spills, a spill-response kit that will include a shovel, adsorbent pads and/or kitty litter, and a collection container Bulk quantities of fuel, oil, or other hazardous material will not be stored on site. These materials will be managed by an off-site contractor who will, on an as-needed basis, perform equipment fueling and maintenance activities. 2.6 WASTE DISPOSAL Hazardous and nonhazardous wastes will be transported off site for appropriate recycling or disposal. Used PPE will generally be managed and disposed of as nonhazardous waste unless generator knowledge indicates it should be managed as hazardous waste. Each waste stream requiring off-site disposal will be sampled and analyzed, as necessary, to ensure that it is properly characterized and profiled and meets the waste acceptance criteria and packaging requirements for the proposed treatment, storage, and disposal facility (TSDF) or recycling facility prior to transport. Hazardous waste will be disposed of only at a hazardous waste disposal facility approved by the Department of the Navy (Navy) and permitted for the disposal of the particular type of hazardous waste generated. Wastes disposed of off site may only be sent to RCRA Subtitle C or RCRA Subtitle D facilities that meet the requirements of 40 CFR, Part (CERCLA Off-Site Rule). 2.7 WASTE TRANSPORTATION Hazardous wastes sent off site for disposal or recycling will be done so in accordance with the DOT Hazardous Material Transportation regulations of 49 CFR, Parts 171 through 177; 40 CFR, Part 262, Subpart B; and 22 CCR, Section 66262, which involve packaging, placarding, labeling, and manifesting requirements, and with appropriate land disposal restriction (LDR) certification notices per 40 CFR, Part 268, and 22 CCR, Section Personnel having the required DOT training will perform all DOT functions. In addition, all transporter and disposal contractors will be subject to the contractor qualification process. Under no circumstances will TtEC personnel sign hazardous waste manifests.

13 Material that does not exhibit one of the nine DOT hazard class characteristics (explosives, gases, flammable/combustible liquids, flammable solids/spontaneously combustible materials, dangerous when wet materials, oxidizers and organic peroxides, toxic materials and infectious substances, radioactive materials, and corrosive materials) is not regulated under DOT rules for hazardous material transportation. If material is suspected to be hazardous, it will be shipped under the appropriate hazard class. All hazardous waste will be transported under DOT hazardous material regulations. Each shipment of a suspected hazardous material will be properly classed using the Hazardous Materials Table in 49 CFR, Part DOT-trained personnel will make all determinations. 2.8 WASTE MINIMIZATION To minimize the volume of waste, the following general guidelines will be followed: Waste materials will not be contaminated unnecessarily. Work will be planned ahead. Materials may be stored in large containers, but the smallest reasonable container will be used to transport the material to the location where it is needed. Cleaning and extra sampling supplies will be maintained outside any potentially contaminated area to keep them clean and to minimize additional waste generation. Mixing of detergents or decontamination solutions will be performed outside potentially contaminated areas. Drop cloths or other absorbent material will be used to contain small spills or leaks. Contaminated materials will not be placed with clean materials. Wooden pallets inside the exclusion zone will be covered with plastic. Material and equipment will be decontaminated and reused when practical. Volume reduction techniques will be used when practical. Waste containers will be verified to ensure that they are solidly packed to minimize the number of containers. Only the size of waste containers adequate to contain the volume of waste generated will be used. Less hazardous substances will be used whenever possible (only the volume of standard solutions needed for testing will be brought; minimal amounts of decontamination water and solvent rinses will be used). 2.9 WASTE MANAGEMENT INSPECTION AND DOCUMENTATION PROGRAM This section presents the waste inspection procedures and documentation program to be employed during the project field activities. ECSD DrWMP_PetroSites_AppC.doc C.2-5 Draft Waste Management Plan

14 2.9.1 Inspection While all waste accumulation areas will be informally inspected on a daily basis, formal inspections of all container accumulation areas will be conducted and recorded at least weekly in accordance with 40 CFR, Part 264, Subpart I, and 22 CCR, Section Inspections will be recorded in a dedicated field logbook, and a weekly inspection checklist will be completed. Containers used for storage of purge and decontamination water will be inspected on a daily basis and the inspections will be logged. The inspections will ensure that drums have adequate secondary containment, are properly labeled, are in good condition (no apparent structural defects or deterioration), and have no visible leaks Documentation Documentation requirements apply to all waste managed during project activities. Field records will be kept of all waste generation activities. All pages of the field data record log will be signed and dated by the supervising field leader entering the data. In addition, the following information will be recorded in the log: Description of waste-generating activities Location of waste generation (including depth, if applicable) Type and volume of waste Date and time of generation Description of any waste sampling Name of person recording information Name of field manager at time of generation Hazardous Waste Manifests and LDR Certification All hazardous waste transported from the site will be accompanied by a Hazardous Waste Manifest. Navy personnel will be responsible for reviewing and signing all waste documentation, including waste profiles, manifests, and LDR notifications (manifest packages). Prior to signing the manifest, the designated Navy official will ensure that pretransport requirements of packaging, labeling, marking, and placarding are met according to 40 CFR, Parts through , and 49 CFR, Parts 100 through 178. The Navy will receive one copy of the manifest; the remaining copies will be given to the transporter. The manifest will be returned to the Navy s signatory official for the facility s recordkeeping requirements. Copies of all manifests for waste generated at the site will be kept in a compliance file within the project files. (The Project Manager will provide the Navy with the generator s copies of the manifest.) ECSD DrWMP_PetroSites_AppC.doc C.2-6 Draft Waste Management Plan

15 An LDR form will accompany the shipment of hazardous waste to the TSDF, which will be notified prior to the waste being sent. The following items must accompany the notification and are included in one of the following facility-specific forms: EPA Hazardous Waste Generator identification number Manifest number, including state disposal application number Waste analysis data Corresponding concentration-based or technology-based treatment standards that will be identified if the waste is also land-disposal restricted RCRA recordkeeping requirements per 40 CFR, Parts through , including retention of signed copies of manifests from the designated facility that received the waste, will be adhered to. Additionally, biennial and exception reporting information will be submitted, as necessary, according to 22 CCR, Sections and , and 40 CFR, Parts and Additional reporting may be required in accordance with 22 CCR, Section , and 40 CFR, Part ECSD DrWMP_PetroSites_AppC.doc C.2-7 Draft Waste Management Plan
