The City will continue to send notice to all facilities on file with benchmark monitoring requirements to remind them of their reporting requirements to TCEQ and will request that a copy of the report also be sent to the Stormwater Management Division , Environmental Management Group . Those who do not submit the benchmark monitoring data to the City will be asked to provide a hard copy of the data upon annual inspection of their facility to be reviewed and filed with industrial inspections records . Compliance Action Plans are reviewed at annual inspection or by March 31 ( whichever is later ) to determine if corrective measures were effective .
V . Clean Rivers Program ( CRP )
The CRP program is coordinated through the Trinity River Authority of Texas ( TRA ). CRP sampling is conducted at eight predetermined sites on a quarterly basis . In June 2016 , the City began sampling monthly for E . coli at the eight previously established CRP sites and eventually added four ( 4 ) additional sites for comprehensive watershed sampling . One additional site was added in FY2017 for a total of thirteen ( 13 ) monthly E . coli sampling locations . Quarterly sampling occurs at the eight ( 8 ) previously established CRP sites and includes additional water quality parameters including : pH , dissolved oxygen , specific conductivity , air temperature , sample temperature , surfactants , chlorine , copper , phenols , ammonia , and visual observation . Lab analyses include testing for : Cadmium , Chromium , Copper , Manganese , Nickel , Zinc , Iron , Lead , Chlorophyll , TKN , Nitrate , Nitrite , Orthophosphate , Total Phosphate , Hardness , and E . coli .
The eight CRP sites are located on larger bodies of water . This provides a broader view of the health of the entire stormwater collection system as well as indicating the presence of any pollutants from illicit discharges upstream . TRA provides all CRP data to the TCEQ on behalf of the participating entities . In September 2014 , the City of Arlington converted to the TRA CRP reporting and sampling schedule , thus sampling may not necessarily align with the City of Arlington ’ s defined fiscal year or annual reporting cycle . Quarterly CRP sampling occurred in November 2018 , February 2019 , May 2019 , and August 2019 .
