<br /> I Wheel wash or tire bath (if necessary)wastewater shall be discharged to a separate on-site
<br /> treatment system or to the sanitary sewer.
<br /> I Application of agricultural chemicals, including fertilizers and pesticides, shall be conducted in a
<br /> manner and at application rates that will not result in loss of chemical to stormwater runoff.
<br /> Manufacturers' recommendations for application rates and procedures shall be followed.
<br /> IBMPs shall be used to prevent or treat contamination of stormwater runoff by pH modifying
<br /> sources. These sources include, but are not limited.to, bulk cement, cement kiln dust, fly ash,
<br /> new concrete washing and curing waters, waste streams generated from concrete grinding and
<br /> I sawing,exposed aggregate processes, and concrete pumping and mixer washout waters.
<br /> Stormwater discharges shall not cause or contribute to a violation of the water quality standard for
<br /> pH in the receiving water.
<br /> ,I Construction sites with significant concrete work shall adjust the pH of stormwater if necessary to
<br /> prevent violations of water quality standards.
<br /> I Table 1 below lists several pollutants that are commonly found on construction sites that have the
<br /> potential to contaminate storm runoff. These pollutants will be present, mainly in areas of building
<br /> and pavement construction. The Contractor and the CSWPPP/TESC coordinator will be
<br /> I responsible for identifying areas where these pollutants are being used and monitor runoff coming
<br /> from these areas. Pollutant sources will be covered with plastic if contaminated runoff is
<br /> observed from these areas. If contaminated runoff is found in the sediment trap or soils, the
<br /> Erosion Control Specialist will direct the Contractor to remove the polluted water/soil and dispose
<br /> Iof it in an approved area offsite.
