Special Condition S8.D of the 2007-2012 Phase I Municipal Stormwater Permit required permittees to collect and analyze data to evaluate pollutant loadings of stormwater discharged from different land uses: high density (HD) residential, low density (LD) residential, commercial, and industrial. To meet the S8.D requirement, Phase I Permittees collected water quality and flow data, sediment data, and toxicity information from stormwater discharges during storm events.https://data.wa.gov/d/d958-q2ciCreated: 2015-05-01Modified : 2015-06-04Update by syncSocrata script at: 2017-01-05 01:12:31.958000
