Environmental Health and Safety
Which of the following best describes the institution’s approach to rainwater management?:
A brief description of the institution’s green infrastructure and LID practices:
WVU has run a Municipal Separate Stormwater System (MS4) since 2014, as prescribed by the West Virginia Department of Environmental Protection's National Pollutant Discharge Elimination System (NPDES). WVU also complies with the Morgantown Utility Board's stormwater ordinance, which prescribes controlling peak flow runoff from 2, 10, and 50 year 24-hour storm events. The main way this is addressed is through bioretention cells and green roofs. WVU has more than 45 bioretention cells on its Morgantown campus. There are also currently 4 green roofs on campus and an additional one planned for a new building. Additional infrastructure includes over 20 underground retention systems and over 20 stormwater detention ponds. WVU's MS4 permit has been extended by the state, but will be resubmitted in 2021. In it's next iteration, WVU will quantify effectiveness of its stormwater sediment and pollutant removal. The waterways that WVU discharges to are designated impaired and have various total maximum daily loads (TMDLs). WVU will also measure that its discharges do not contribute to those limits.
In addition to the stormwater program, The Stormwater Management Construction Guideline dictates that new impervious surface over 3,000 square feet must capture, treat, and manage the first 1-inch of runoff and that low impact development features are the preferred method for doing this. The guideline also dictates construction methods and materials that must be used when building bioretention cells.
