From 2017 to present, Bluestone has performed Multiple Separate Storm Sewer (MS4) Support for ANC.

Description:

Avatar and Team Subcontractor Burns and McDonnell are providing design services at the Appleton ARC in Appleton, WI. The facility experiences stormwater runoff and ponding issues at multiple locations on the site. The pavement has also experienced significant deterioration since its placement. The project consists of the following:

MS4 Registration Statement: Bluestone prepared ANC’s registration statement for continued coverage under the General Virginia Pollutant Discharge Elimination System (VPDES) Permit for Discharges of Stormwater from MS4s. Bluestone collected the following information for inclusion on the registration form: general facility and contact information; MS4 information including outfall data, drainage, receiving waters and impairments; and physically interconnected MS4s. Bluestone prepared the form and certification statement for ANC to submit to the Virginia Department of Environmental Quality (VDEQ).

Update MS4 Program Plan: Bluestone updated ANC’s exiting MS4 Program Plan based on facility modifications as well as ANC personnel input. The Plan was updated to comply with the new General VPDES Permit. Bluestone developed best management practices for ANC to implement to address each of the following minimum control measures required in the permit: public education and outreach; public outreach and involvement; illicit discharge detection and elimination; construction stormwater management; post-construction stormwater management; and good housekeeping and pollution prevention. Bluestone perform a site assessment to evaluate best management practice opportunities, interview personnel, and review stormwater documentation. As part of the plan development, Bluestone also created inspection forms for dry weather outfall screenings, suspect illicit discharges, and stormwater management facilities.

Chesapeake Bay TMDL Action Plan: ANC is required to develop and implement a plan to reduce phosphorus, nitrogen, and total suspended solids in their stormwater discharges. Bluestone conducted a site investigation, reviewed documents, conducted personnel interviews, and performed regulatory research as part of rewriting ANC’s existing TMDL Action Plan. Bluestone calculated pollutant loads from existing and new sources; reviewed the current MS4 permit authority and implementation capabilities; and determined the existing, new, and modified legal authorities necessary to meet required reductions. The revised plan addressed the structural and non-structural best management practices (BMPs) ANC has implemented to achieve compliance with the required pollutant load reductions.

Annual Stormwater Management Training: Bluestone developed a presentation for ANC’s use in training facility personnel on stormwater issues. The training was a Power Point covering stormwater topics such as construction, spill response, recognition and reporting of illicit discharges, and good housekeeping and pollution prevention. The training materials focused on ANC’s unique operations to help them comply with the Public Education and Outreach portion of their MS4 Program Plan.

Public Outreach: Bluestone designed and prepared outreach brochures and cards related to stormwater management techniques implemented at ANC. The brochures and cards focused on spill prevention and response, illicit discharge identification and elimination, good housekeeping and pollution prevention, and general stormwater awareness. Cards were prepared in both English and Spanish and provided to ANC staff.

Stormwater Pollution Prevention Plan (SWPPP): Bluestone revised ANC’s SWPPP to comply with the VPDES General Permit, to reflect changes at the site, and to streamline the report based on ANC personnel request. The plan was developed to comply with ANC’s revised MS4 Program Plan to address the good housekeeping and pollution prevention minimum control measure. Bluestone conducted a 2-day site assessment and reviewed all areas where pollutants could potentially enter the MS4. The site assessment also included a review of all inflows and outfalls from the MS4, personnel interviews, and document reviews. The Plan included a description of the facility and all high-priority areas (as defined in the General Permit), stormwater controls already in place, direction of storm water flow through and from the installation, and the location of the outfalls. Bluestone developed written procedures designed to reduce and prevent pollutant discharges and checklists to conduct an annual comprehensive site compliance evaluation. The plan also included an inspection and maintenance schedule for site-specific source controls ad a spill reporting log to track any discharges, releases, or spills including the date of incident; material discharged, released, or spilled; and quantity discharged, released, or spilled.

MS4 Annual Report Template: Bluestone prepared an Annual Repot Template for ANC’s use in completing their MS4 Annual Repot submission. The report template was developed in accordance with the new VPDES General Permit and included tables for ANC to report all required information.

Stormceptor Maintenance: Bluestone was contracted to perform maintenance of eight subsurface stormceptors. Bluestone contracted for a vacuum truck to remove sediment and oil collected in the stormceptors. Following sediment removal, Bluestone performed four quarterly inspections of the eight stormceptors and provided a recommended maintenance schedule for ANC’s future use.
