The Waste Management Board adopted amendments to 9VAC20-80, Solid Waste Management Regulations. The amendments clarify the closure definition and procedure with particular reference to landfills subject to §10.1-1413.2 of the Code of Virginia; address plans and actions related to the management of landfill gas and odors; provide an option for facilities to apply for research, design, and development; and delete automatic public hearings for certain permit or amendment issuance process. The amendments also broaden the definition of "airport" to include military airfields. Finally, the amendments incorporate citations referencing two new statutory provisions for a landfill location that is protective with respect to water supplies and wetlands and certification of permit application consistency with local government waste management plans. http://legis.state.va.us/codecomm/register/vol25/iss02/f9v2080.html.
