9VAC25-32-580. Sludge disposal.

Permits for sludge disposal practices will be issued through other state and federal regulations and are not subject to this regulation. Such practices may include:

1. Incineration. Emission quality control requirements will be established in accordance with state and federal regulations. The generated ash is required to be properly managed in accordance with local, state and federal regulations. Applicable regulatory requirements in addition to this regulation may involve permits issued by the appropriate state and federal agencies. Setback distance requirements will be established on a site specific basis in accordance with the applicable regulations.

2. Landfill. Management of stabilized sludge suitable for topdressing of completed landfill areas will be subject to state and federal regulations. Codisposal of sludge within municipal solid waste landfills is subject to state and federal regulation. Codisposal requirements have included:

a. Stabilization treatment of sludges.

b. Dewatering of sludges by methods designed to achieve a suspended solids level of 20% or more, or a treated sludge sample passes the paint filter test standards for free water.

c. A nonhazardous declaration from the owner.

3. Lagooning (surface disposal). When these facilities are closed by burying the wastes in place, they may be considered to be surface disposal sites. A closure plan shall be provided to the appropriate agencies.

4. Dedicated sites. The primary purpose of surface disposal sites is to allow frequent long-term sludge application at a single location at amounts that exceed agronomic rates but not for the purpose of reclaiming disturbed soils. Sludge disposal operations on dedicated sites will be subject to local, state and federal regulations including site management practices. Permits will be issued through state and federal regulations to protect public health and the quality of state waters. Any dedicated site may be subject to local zoning requirements and may be recorded as a dedicated site in the appropriate circuit court deed book by filing a Sludge Disposal Site Dedication Form.
