http://www.epa.gov/ozone/science/ods/classtwo.html.

1.2.2 Contractor Generated Hazardous Waste

Contractor generated hazardous waste is materials that, if abandoned or disposed of, may meet the definition of a hazardous waste. These waste streams would typically consist of material brought on site by the Contractor to execute work, but are not fully consumed during the course of construction. Examples include, but are not limited to, excess paint

SECTION 01 57 19 Page 3 June 04, 2024 thinners (i.e. methyl ethyl ketone, toluene), waste thinners, excess paints, excess solvents, waste solvents, and marine biofouling agents.

1.2.3 Electronics Waste

Electronics waste is discarded electronic devices intended for salvage, recycling, or disposal.

1.2.4 Environmental Pollution and Damage

Environmental pollution and damage is the presence of chemical, physical, or biological elements or agents which adversely affect human health or welfare; unfavorably alter ecological balances of importance to human life; affect other species of importance to humankind; or degrade the environment aesthetically, culturally or historically.

1.2.5 Environmental Protection

Environmental protection is the prevention/control of pollution and habitat disruption that may occur to the environment during construction.

The control of environmental pollution and damage requires consideration of land, water, and air; biological and cultural resources; and includes management of visual aesthetics; noise; solid, chemical, gaseous, and liquid waste; radiant energy and radioactive material as well as other pollutants.

1.2.6 Hazardous Debris

As defined in paragraph SOLID WASTE, debris that contains listed hazardous waste (either on the debris surface, or in its interstices, such as pore structure) in accordance with 40 CFR 261. Hazardous debris also includes debris that exhibits a characteristic of hazardous waste in accordance with 40 CFR 261.

1.2.7 Hazardous Materials

Hazardous materials as defined in 49 CFR 171 and listed in 49 CFR 172.

Hazardous material is any material that: Is regulated as a hazardous material in accordance with 49 CFR 173; or requires a Safety Data Sheet (SDS) in accordance with 29 CFR 1910.120; or during end use, treatment, handling, packaging, storage, transportation, or disposal meets or has components that meet or have potential to meet the definition of a hazardous waste as defined by 40 CFR 261 Subparts A, B, C, or D.

Designation of a material by this definition, when separately regulated or controlled by other sections or directives, does not eliminate the need for adherence to that hazard-specific guidance which takes precedence over this section for "control" purposes. Such material includes ammunition, weapons, explosive actuated devices, propellants, pyrotechnics, chemical and biological warfare materials, medical and pharmaceutical supplies, medical waste and infectious materials, bulk fuels, radioactive materials, and other materials such as asbestos, mercury, and polychlorinated biphenyls (PCBs).

1.2.8 Hazardous Waste

Hazardous Waste is any material that meets the definition of a solid waste and exhibit a hazardous characteristic (ignitability, corrosivity, reactivity, or toxicity) as specified in 40 CFR 261, Subpart C, or

SECTION 01 57 19 Page 4 June 04, 2024 contains a listed hazardous waste as identified in 40 CFR 261, Subpart D.

1.2.9 Land Application

Land Application means spreading or spraying discharge water at a rate that allows the water to percolate into the soil. No sheeting action, soil erosion, discharge into storm sewers, discharge into defined drainage areas, or discharge into the "waters of the United States" must occur.

Comply with federal, state, and local laws and regulations.

1.2.10 National Pollutant Discharge Elimination System (NPDES)

The NPDES permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States.

1.2.11 Oily Waste

Oily waste are those materials that are, or were, mixed with Petroleum, Oils, and Lubricants (POLs) and have become separated from that POLs.

Oily wastes also means materials, including wastewaters, centrifuge solids, filter residues or sludges, bottom sediments, tank bottoms, and sorbents which have come into contact with and have been contaminated by, POLs and may be appropriately tested and discarded in a manner which is in compliance with other state and local requirements.

This definition includes materials such as oily rags, "kitty litter" sorbent clay and organic sorbent material. These materials may be land filled provided that: It is not prohibited in other state regulations or local ordinances; the amount generated is "de minimus" (a small amount);

it is the result of minor leaks or spills resulting from normal process operations; and free-flowing oil has been removed to the practicable extent possible. Large quantities of this material, generated as a result of a major spill or in lieu of proper maintenance of the processing equipment, are a solid waste. As a solid waste, perform a hazardous waste determination prior to disposal. As this can be an expensive process, it is recommended that this type of waste be minimized through good housekeeping practices and employee education.

1.2.12 Regulated Waste

Regulated waste are solid wastes that have specific additional federal, state, or local controls for handling, storage, or disposal.

1.2.13 Sediment

Sediment is soil and other debris that have eroded and have been transported by runoff water or wind.

1.2.14 Solid Waste

Solid waste is a solid, liquid, semi-solid or contained gaseous waste. A solid waste can be a hazardous waste, non-hazardous waste, or non-Resource Conservation and Recovery Act (RCRA) regulated waste. Types of solid waste typically generated at project sites may include:

1.2.14.1 Debris

Debris is non-hazardous solid material generated during the dredging activities that exceeds 2.5-inch particle size that is: a manufactured

SECTION 01 57 19 Page 5 June 04, 2024 object; plant or animal matter; or natural geologic material (for example, cobbles and boulders), broken or removed concrete, masonry, and rock asphalt paving; ceramics; roofing paper and shingles. Inert materials may be reinforced with or contain ferrous wire, rods, accessories and weldments. A mixture of debris and other material such as soil or sludge is also subject to regulation as debris if the mixture is comprised primarily of debris by volume, based on visual inspection.

1.2.14.2 Material not regulated as solid waste

Material not regulated as solid waste is nuclear source or byproduct materials regulated under the Federal Atomic Energy Act of 1954 as amended; suspended or dissolved materials in domestic sewage effluent or irrigation return flows, or other regulated point source discharges;

regulated air emissions; and fluids or wastes associated with natural gas or crude oil exploration or production.

1.2.14.3 Non-Hazardous Waste

Non-hazardous waste is waste that is excluded from, or does not meet, hazardous waste criteria in accordance with 40 CFR 263.

1.2.14.4 Recyclables

Recyclables are materials, equipment and assemblies such as doors, windows, door and window frames, plumbing fixtures, glazing and mirrors that are recovered and sold as recyclable, wiring, insulated/non-insulated copper wire cable, wire rope, and structural components. It also includes commercial-grade refrigeration equipment with Freon removed, household appliances where the basic material content is metal, clean polyethylene terephthalate bottles, cooking oil, used fuel oil, textiles, high-grade paper products and corrugated cardboard, stackable pallets in good condition, clean crating material, and clean rubber/vehicle tires. Metal meeting the definition of lead contaminated or lead based paint contaminated may not be included as recyclable if sold to a scrap metal company.

1.4 ENVIRONMENTAL PROTECTION REQUIREMENTS

Provide and maintain, during the life of the contract, environmental protection as defined. Plan for and provide environmental protective measures to control pollution that develops during construction practice.

Plan for and provide environmental protective measures required to correct conditions that develop during dredging. Protect the environmental resources within the project boundaries and those affected outside the limits of work during the entire duration of this Contract. Comply with federal, state, and local regulations pertaining to the environment, including water, air, solid waste, hazardous waste and substances, oily substances, and noise pollution.

Tests and procedures assessing whether construction operations comply with Applicable Environmental Laws may be required. Analytical work must be performed by qualified laboratories; and where required by law, the laboratories must be certified.

1.4.1 Conservation Measures for the Protection of Aquatic Resources

The following measures are non-discretionary actions required to protect species listed as threatened or endangered under the endangered species act (ESA). These measures are also listed under the Avoidance and Minimization Measures for Dredging Activities in the biological opinions issued by the USFWS and NMFS.

(1) Dredging at depths of less than 20 feet will be avoided to the maximum extent achievable.

(2) Maintenance dredging will only be conducted in the authorized channel to the authorized depths.

(3) The contractor will notify the Government of the project dredging schedule and plans as soon as they are known, and will keep the Government informed of any schedule changes. The Government will notify USFWS, NMFS, and CDFW.

(4) The maintenance dredging work window extends from August 1 through October 31 in the Sacramento DWSC.

(a) Within the Sacramento DWSC, to avoid peak migration of juvenile salmonids and adult presence in the project area, dredging will proceed from downstream to upstream during the environmental work window from August 1 until October 31.

(5) If two dredgers are used in a single channel, they shall not operate in the same reach. Alternatively, if two dredgers are used in the same reach, a turbidity curtain must be used downstream of each dredger to reduce the length of channel that fish are exposed to elevated turbidity.

(6) All slurry pipe placement and bank stabilization activities shall specifically avoid known locations containing special status species and/or designated critical and other sensitive habitats to the maximum

SECTION 01 57 19 Page 8 June 04, 2024 extent feasible.

(7) If significant damage to wetlands or associated vegetation occurs, the Contractor shall restore the area to pre-existing conditions.

(8) The contractor is responsible for providing erosion and sediment control measures in accordance with Federal, State, and local laws and regulations to ensure compliance with water quality standards. The Contractor is responsible for the placement of temporary and permanent erosion and sediment control best management practices. These may include, but are not limited to, vegetation cover, stream bank stabilization, slope stabilization, silt fences, construction of terraces, interceptor channels, sediment traps, inlet and outfall protection, diversion channels, and sedimentation basins. Silt fences and other non-natural temporary measures shall be removed after the area has been stabilized.

1.4.2 Additional Conservation Measures for the Protection of Aquatic Resources for Cutterhead Dredgers

(1) If using a cutterhead dredger, the cutterhead will not be operated more than three feet above the channel bottom.

(2) Suction will not be employed while the dredge head is deployed and retrieved through the water column.

(3) The dredger will maintain the suction head at a constant elevation near the channel bed when dredging, to reduce the field of influence where fish may be entrained into the dredge pipe.

(4) Draghead deflectors will be installed on the leading edge of hopper dredge dragheads to minimize the risk of incidental take of benthic species such as green sturgeon. The deflector is designed to have a plowing effect of at least 6 inches.

1.4.3 Additional Conservation Measures for the Protection of Aquatic Resources for Clamshell Dredgers

(1) Multiple horizontal dredge cuts will be taken where a thick horizontal volume needs to be dredged to avoid overfilling the bucket and causing spillage.

(2) Once the clamshell bucket reaches the target depth, it will be fully closed before the dredge operator begins to raise it to the surface of the water column. This method, coupled with the use of a mechanical cable arm environmental clamshell bucket, minimizes the potential for generating turbidity in the water column.

(3) Once out of the water, the clamshell bucket will place dredged sediment directly into the scow. Sediment will not be released from the bucket until it is fully inside the scow. Within the scow, dredged sediment will pass through a 12-inch-by-12-inch grid to prevent any solid debris or artificial objects from entering the scow. Solid debris and artificial objects trapped on the grid will be removed and brought to an approved waste disposal site. Large woody debris with environmental value will be returned to the channel where not a hazard to navigation. The bucket will be held open over the grid within the scow until all the sediment and water has drained from within it to minimize the potential for resuspension of the sediment in the water

SECTION 01 57 19 Page 9 June 04, 2024 column.

(4) The load line on disposal barges used for mechanical dredging will be predetermined based on channel conditions, and the barge will not be filled above this predetermined level. Under no circumstance will scows be loaded to more than 90% capacity.

(5) Untreated water shall not be overflowed, decanted, discharged, or otherwise released from the vessel.

(6) Before each disposal barge is transported to a placement site, the dredging contractor and a site inspector must certify that it is filled correctly. Scows will be inspected to ensure no loss of sediment during loading and transport.

(a) If turbidity levels reach a value that represents 75% of the relevant allowable limit as identified in the MOU or WDR for any reason, the Corps' contractor will immediately slow the dredge rate by 50% to prevent turbidity levels from increasing further (i.e., if the cycle time for the bucket to descend, collect material, and drop that material in the scow is 30 seconds when the violation occurs, the revised cycle time should be 45 seconds until levels return to below 75% relevant allowable limits).

(b) If turbidity levels reach a value that represents 90% of the relevant allowable limit as identified in the MOU or WDR for any reason, the Corps' contractor will deploy a type II turbidity curtain, bubble curtain, or other similar measure to prevent the plume from migrating away from the dredge site.
