(08-14-124.)
Excerpt: Municipal Separate Storm Sewer System (MS4) permit
Fairfax County's Municipal Separate Storm Sewer System (MS4) permit requires the county to prevent the discharge of pollutants (often called "non-point source" pollutants) such as engine oil, fertilizer, pet waste and trash from the stormwater management system into waterways to the maximum extent practicable. The permit also prohibits non-stormwater discharges into the storm drainage system, such as from sanitary sewer connections or illegal dumping. It also requires storm event monitoring and assessment of the effectiveness of stormwater controls being used in the county. Annual reports submitted to the Virginia Department of Environmental Quality summarize the efforts of government agencies, non-profit agencies and private organizations in managing stormwater runoff and limiting non-point source pollution to the maximum extent practicable activities and collective efforts in support of the mission of effective stormwater control include:
- Defining a strategic plan for comprehensive stormwater management.
- Developing watershed management plans.
- Implementing water quality and quantity control practices.
- Conducting inspection and maintenance programs for stormwater control systems and structures to ensure their effectiveness.
- Conducting stream monitoring and evaluation programs.
- Providing technical support to residents and developers.
- Sharing resources and information for the purposes of educating residents and developing strategies to promote good water quality improvement practices.
Notice of Inspection
Within 30 to 45 days of the facility inspection, a formal Notice of Inspection (NOI) is sent via certified mail to the facility owner describing the inspection findings and any required maintenance that must be performed. When a stormwater facility has multiple owners, the NOI may be mailed to the property management company rather than to each individual owner. Where there are multiple stormwater facilities on a single site, the NOI reports for those multiple facilities may be combined into a single mailing. The NOI typically includes:
- Condition Assessment Report (CAR) with corresponding photos detailing the required maintenance items observed during the inspection
- Copy of approved facility plan sheets
- Copy of recorded Private Maintenance Agreement/Maintenance Agreement for Stormwater Management Facilities (PMA) (described further below)
- Maps showing the facility and parcel location
- General Maintenance Guidelines specific for the type of facility
- Maintenance Contractor List
- Maintenance Activity Report (MAR) (described further below). Completion of the MAR is required for each facility requiring maintenance and must include photos and any other supporting documentation to close out the inspection.
Required maintenance items are listed in the CAR, which is the first attachment in the NOI. Each maintenance item refers to one or more of the attached photos. Maintenance items usually require that the facility be restored to its approved plan condition, meaning its original design condition as shown in the approved facility plan sheets. Sediment accumulation and structural deterioration, among other common maintenance problems, naturally occur over time and eventually impact facility functionality. The maintenance items listed are needed to either restore proper functionality or to ensure continued functionality of the stormwater facility.
The inspection record for a stormwater facility in need of maintenance remains “open” until all required maintenance specified in the CAR is fully complete. Forty-five days are provided from the time of the initial NOI delivery to the next follow-up phase. If an adequate response is not received within that time, then follow-up letters are mailed as reminders that a response is still required. A total time of 135 days is provided for voluntary compliance before the facility moves into the enforcement phase.
