During construction, inspection of erosion and sediment controls and stormwater management controls, also known as best management practices (BMPs), is a major focus of the DEQ’s plan to ensure compliance with Virginia’s environmental laws and regulations. Virginia’s Erosion and Sediment Control (ESC) and Stormwater management laws and regulations are intended to minimize sediment loss with appropriate controls in place. Inspection of BMPs is critical to preventing potential water quality impacts from construction activities. DEQ inspects these BMPs for proper installation, performance and maintenance. DEQ is using a team of DEQ staff inspectors augmented by third-party contractors to ensure adequate coverage during all phases of construction. A combination of factors is evaluated when prioritizing inspection resources. These criteria include routine inspections and audits, complaint investigations, evaluations of monitoring data from established monitoring stations at select stream crossing locations, topography, weather conditions and the phase of construction activity in upland areas, wetlands and stream crossings. Staff inspection reports for both complaint-specific investigations and routine spread-by-spread inspections are available to view.

In addition to erosion and sediment control and stormwater inspections, DEQ will also be evaluating compliance with the many additional requirements imposed by the Section 401 Water Quality Certification. These additional requirements address protection of karst features, hydrostatic testing, acid soils mitigation, steep slope best practices, spill prevention control and countermeasures, riparian buffer protections and surface water withdrawals.

Stop work authority

Legislation adopted by the 2018 General Assembly authorizes DEQ to issue a stop work instruction for land-disturbing activities related to the construction of a natural gas transmission pipeline under certain situations (2018 Va. Acts Chs. 297 and 298). DEQ may issue a stop work instruction on part of a site if the agency determines that there has been a substantial adverse impact to water quality or that an imminent and substantial adverse impact to water quality is likely as a result of such land-disturbing activities. The stop work instructions are a temporary measure to correct deficiencies before resuming work. The agency has developed guidance that details the stop work instruction process.

For more information regarding the background and regulatory approvals for the Mountain Valley Pipeline project, please see the Mountain Valley Pipeline page. Information on the overall regulatory process for natural gas pipeline construction projects can be found on our Protection Requirements for Pipelines page

Pollution & Non-compliance Reporting Information

DEQ strives to respond to all pollution and non-compliance complaints. Many complaints include photos or videos which are helpful. This complaint documentation is very valuable to the agency as it provides visual and locational information which enables DEQ to prioritize and direct inspection resources. Any pollution and non-compliance complaints DEQ receives are entered into and processed through our Pollution Response Program (PReP) database prior to being investigated. Additionally, if erosion and sediment controls are overwhelmed, developers must report the incident to DEQ and respond promptly to restore control measures. Sediment loss due to weather conditions does not necessarily create a “violation.”

Report pollution and non-compliance online here. An Incident Report (IR) number will be provided upon report submission and can be used to track the status of the report/complaint in the PReP database and Weekly Report (linked at the top of this page). Additionally, the full PReP database is available to download. This list of incident investigations and their respective statuses is updated monthly.

DEQ will continue to coordinate with other state agencies and the U.S. Army Corps of Engineers to ensure all permit conditions are enforced. DEQ is also coordinating with local governments that have signed on to the voluntary Memorandum of Agreement to ensure compliance with the site-specific plans that have been approved. In addition to using DEQ's online PReP reporting form, you can submit your pollution and non-compliance reports to these other agencies' phone lines and emails listed on our Reporting Pipeline Concerns page depending on the nature of your complaint.

Local citizen watch groups are also submitting their information to the agency. This multi-faceted plan of evaluation and coordinated inspections, and DEQ’s enforcement capabilities will ensure developers comply with Virginia’s rigorous regulatory requirements designed to protect water resources.

Lastly, real-time water monitoring reports are available here. Turbidity, temperature, specific conductance, dissolved oxygen and pH are measured every 5 minutes, and all data are available online within one to two hours of collection.

Incident Report Log
