  2. Protection of Public Streets and Stormwater Facilities.
    The performance standard for protecting public streets and stormwater facilities has not been met if there is deposition other than tracking, of more than two gallons (twenty-seven one-hundredths cubic feet) per day of soil, dirt, mud, or debris from the project site onto adjacent public streets and/or in a stormwater system within a public right-of-way.
     
  3. Proper Washout of Concrete Trucks and Equipment.
    The performance standard for ensuring the proper washout of concrete trucks and equipment has not been met if there is observation or evidence of concrete washout material within a drainage area, stormwater facility, water body, or area where a stormwater facility is proposed.
