DEQ Press Release on ACP Stormwater Methodology

From VA DEQ: DEQ Approves Final Atlantic Coast Pipeline Stormwater Methodology, Rolls out Landmark Monitoring, Compliance and Enforcement Strategy

RICHMOND, VA. – Today, the Virginia Department of Environment Quality (DEQ) announced that it has received a final document detailing Atlantic Coast Pipeline, LLC’s (ACP) proposed compliance methodology for meeting Virginia’s post construction water quality and quantity requirements. The methodology was subjected to a thorough review and DEQ rejected several earlier versions of this technical document before approving the final released today.

DEQ also received similar technical documents from the Mountain Valley Pipeline (MVP) describing MVP’s proposed engineering methods that will be used before drafting detailed site plans for stormwater management. Both documents are available at:

DEQ is continuing to review detailed, project-specific erosion and sediment control and stormwater plans that the agency has required ACP and MVP to submit for every foot of land disturbance related to pipeline construction. Once approved, these requirements, contained in Virginia’s Erosion and Sediment Control (ESC) and Stormwater Management (SWM) regulations will manage runoff during and after construction to protect water quality. In response to DEQ’s comments, ACP continues to submit revisions to ESC and SWM plans to address deficiencies and concerns identified during the agency’s review.

“Protecting water quality and water supplies requires controlling runoff and these plans are critical to that goal. They need to be complete. DEQ staff and its contractors are taking care to scrutinize all aspects of the plans to ensure they meet rigorous design standards,” said Director David K. Paylor.

DEQ also announced that it will implement a comprehensive program to monitor construction of both the ACP and the MVP to ensure compliance with water quality standards, and take strong enforcement action if violations occur.

See the full press release for details of the monitoring, compliance, and enforcement strategies.

In the press release Paylor also said, “DEQ will hold the developers to the highest construction standards and will take swift and strong enforcement action for any problems that occur.” However, DEQ does not have the on-the-ground resources to do the necessary monitoring, which means that when the (inevitable) violations happen, the damage will be done, and in many cases, it cannot be repaired – even with the mitigation funds in the undercover deal signed by McAuliffe. And landowners will get nothing for the damage done on their properties.
