Virginia Water Quality Improvement Fund; publicly owned treatment works, nutrient reduction.

Authorizes the Director of the Department of Environmental Quality (the Department) to issue grants from the Virginia Water Quality Improvement Fund for water quality improvements, including cost effective technologies to reduce loads of total phosphorus, total nitrogen, or nitrogen-containing ammonia, in order to meet certain requirements of ammonia-related regulations that are more stringent than those adopted by the State Water Control Board (the Board). The bill also requires the Department to prepare a preliminary estimate of the amount and timing of Water Quality Improvement Grants required to fund projects to reduce loads of nitrogen-containing ammonia at certain levels based on an estimate of the anticipated range of costs for all publicly owned treatment works if the Board were to adopt the 2013 Aquatic Life Ambient Water Quality Criteria for Ammonia published by the U.S. Environmental Protection Agency. This bill is identical to
