Catoctin Creek Water Quality Implementation Plan

Residential Cost-Share Program for Onsite Wastewater Systems


Residents within the Catoctin Creek Watershed may be eligible for federal grant money to help evaluate and make repairs to their onsite wastewater treatment systems (OWTSs).

imnage of catoctin creekThe grant money, made available by the U.S. Environmental Protection Agency, will be supplied to homeowners to pay for a minimum of 50 percent of costs incurred from making corrections to their OWTSs, and up to 75 percent of costs for those below the median income in Loudoun County. You must live in the Catoctin Creek watershed to participate.

This webpage is designed to provide information to homeowners on the grant funds available for evaluating, repairing, replacing or installing onsite wastewater treatment systems.

The Loudoun County Health Department will distribute the grant monies to qualified residential homeowners. An agricultural grant program for livestock fecal coliform reductions is being administered by the Loudoun Soil and Water Conservation District. Follow the links below for more information about both programs.

Background on TMDL Implementation Plan

Catoctin Creek has been listed as impaired by the Virginia Department of Environmental Quality (DEQ) due to elevated fecal coliform bacteria levels that exceed Virginia's water quality standards. The DEQ has created a TMDL plan for Catoctin Creek, which aims to mitigate its impairment and bring it back into compliance with Virginia's standards. The goal of the plan is to make Catoctin Creek suitable for recreational uses, including swimming and fishing. Setting TMDLs for impaired waters was mandated in Section 303(d) of the Clean Water Act of 1972.

A TMDL, or Total Maximum Daily Load, is the maximum amount of a specific pollutant that a body of water can assimilate without exceeding the state's water quality standard for that pollutant; in Catoctin Creek's case, fecal coliform. The Virginia Department of Conservation and Recreation has organized a TMDL Implementation Plan that addresses, and provides grant funding for the correction of fecal coliform contributions from both livestock and failing onsite wastewater treatment systems.

Local residents were involved in the development of the implementation plan, including representatives from water resource monitoring groups, members of the local farming and agricultural communities, and business representatives.
