City of Alexandria
Late last month I put together a list of environmental bills that were going to come up in the Virginia General Assembly for the 2017 session. I would like to go into more detail on the bills related to Alexandria’s combined sewer system, and provide you with some updates on those bills.
The City of Alexandria has an outdated wastewater management system. Their combined sewer system, which collects both wastewater and stormwater for treatment at Alexandria Renew, is prone to overflow events during periods of heavy rainfall. Overflows discharge millions of gallons of raw sewage into the Potomac River- up to 70 million gallons per year, according to the Potomac Riverkeepers. Raw sewage discharged into the Potomac River negatively impacts water quality and wildlife; causes major public health risks; and exacerbates nutrient pollution in the Chesapeake Bay- a watershed that the state of Virginia has pledged to clean up, through the EPA-mandated Chesapeake Clean Water Blueprint.
Two of the original bills in the 2017 legislative session -House Bill 1423 and Senate Bill 819- targeted discharges from the City of Alexandria’s combined sewer overflow (CSO) system.
House Bill 1423, was first referred to the Committee on Commerce and Labor, has since been referred to the Committee on Agriculture, Chesapeake, and Natural Resources (on 1/19). This bill calls for the Department of Environmental Quality to identify CSO outfalls that discharge into the Potomac River and lay out actions to bring these outfalls into compliance with federal and state laws by July 1, 2027. This bill would directly target Alexandria’s CSO Outfall Site 001.
Senate Bill (SB) 819, introduced by Senator Adam Ebbin (who represents part of Alexandria) called for the City to complete an assessment of needed system improvements and discharges from Alexandria Renew’s outfall sites to the Potomac River watershed by January 1, 2029. Failure to do so would cause the State Water Control Board to hold off on renewing the Virginia Pollutant Discharge Elimination System permit for this wastewater facility. This bill was stricken from the docket of the Committee on Agriculture, Conservation, and Natural Resources on January 12, before it could reach the Senate floor.
Senate Bill 819 seems to have been scrapped in favor of stronger regulation. On January 12, the same committee that killed SB 819 introduced a new bill, which would require the City of Alexandria to eliminate all discharges of sewer into the Potomac River watershed by July 1, 2020, with severe financial penalties enacted for failure to comply. The committee ultimately adopted a substitute (on 1/19) to bring to the Senate floor, lengthening this timeline to 2025.
The City of Alexandria needs to update and reconfigure its combined sewer system to eliminate overflow events, and it needs to do so sooner than the timelines laid out in the recent House and Senate bills if Alexandria is serious about improving water quality and decreasing public health risks. The City of Alexandria released their Long Term Control Plan Update late last year which lays out how they will deal with this issue, but the timeline for this plan is also too long. Many of the proposed fixes would not be fully implemented for at least another 15 years. The DEQ still needs to approve this plan and the City must finalize funding. The Long Term Control Plan Update is several steps away from being put into motion.
The first wastewater treatment facility in the City of Alexandria was constructed in 1956; a combined sewer system existed long before that. This discharge issue is one that has been occurring for decades. It is time to eliminate all discharges of raw sewage to the Potomac River.
