Title
Consider A Resolution Authorizing The City Manager To Enter Into A Three-Year Contract Agreement With Southern Petroleum Laboratories, Inc. For Industrial Pretreatment Sampling And Analysis Services In An Amount Not To Exceed $130,000.00 Annually, For A Total Amount Not To Exceed $390,000.00.
Body
BACKGROUND:
The City of Carrollton pretreatment program is federally mandated by the Environmental Protection Agency (EPA) and requires periodic monitoring of industrial wastewater discharges from Carrollton industries to the sanitary sewer system. This agenda item seeks authorization to contract with Southern Petroleum Laboratories, Inc. for this sampling and laboratory analysis. Under the pretreatment program, the City of Carrollton must ensure consistent quality control, documentation, and legal defensibility of all field sampling and laboratory analyses.
Due to the EPA certification and technical services required for this program, laboratory selection is based on a comparison of multiple certified laboratories. Ranking criteria consist of analytical result accuracy as compared to known standards, technical accuracy and precision, turnaround times, quality of field services, and value. To meet program goals, staff recommends that Southern Petroleum Laboratories, Inc. be selected to conduct its wastewater monitoring.
FINANCIAL IMPLICATIONS:
This item is funded from the approved Environmental Services operational budget. The direct cost of sampling and analysis is fully recovered from the regulated industries including administrative fees to partially recover administrative costs.
COST CENTER LINE ITEM BUDGET AMOUNT
261001 Environmental Services 61190 - Professional Services $130,000.00
IMPACT ON COMMUNITY SUSTAINABILITY:
Compliance with the pretreatment program’s monitoring requirements ensures that the discharges from the City’s regulated industries conform to ordinance limits and prohibitions. This minimizes, if not prevents:
- Discharges of excessive oils and suspended solids, which could cause blockages in the sewer lines and consequent sanitary sewer overflows;
- Discharges of corrosives, toxics, and flammables that could damage the infrastructure and pose a life and safety risk;
- Interference with wastewater treatment and sludge quality at the treatment plant;
- Trinity River water quality impacts from pollutants that are not removed by treatment.
STAFF RECOMMENDATION/ACTION DESIRED:
Staff recommends City Council approval of a three-year contract with Southern Petroleum Laboratories for sampling and laboratory analysis, in an annual amount not to exceed $130,000.00, for a total amount not to exceed $390,000.00.
