Roadways
The City of Arlington operates and maintains public streets and roads in a manner to minimize the discharge of pollutants to the MS4 , including those pollutants related to deicing and / or sanding activities . The program includes street sweeping activities ( previously described ), spill response ( hazardous and non-hazardous materials to roads and streets ), and deicing and / or sanding activities .
The City spill response program is explained in more detailed under MCM 3 : Illicit Discharge Detection and Elimination , Section VIII : Spill Prevention and Response .
In times of inclement weather , the city may deploy sanding and / or deicing crews . The city experienced approximately one ( 1 ) event during the reporting period that necessitated a severe weather response totaling $ 5208 in labor costs .
Street sweeping recovers deicing material after storm events . The recovered material contains an unknown amount of sediment and debris that were present on streets before deicing . Actual recovery rates of the deicing material vary depending on weather conditions .
