Project Highlights:
- Complete reevaluation of the technical basis of the biochemical oxygen demand (BOD) local limit
- Work together with the City to develop a technically-based BOD limit
- Over $500,000 in savings to the industry and increased BOD surcharge revenue for the City
- Improved industrial pretreatment program for the City
EEC Environmental (EEC) was retained by a large food manufacturing facility to help them comply with an extremely stringent BOD sewer discharge limit.
EEC’s successfully upgraded the industry’s biological treatment system but also discovered that the City’s wastewater local limits for BOD were unreasonable with a questionable technical basis. EEC investigated the basis of the BOD limit, calculated a technically-based limit, and negotiated a reasonable BOD limit with the City on behalf of our client.
The new BOD limit was adopted by the City, avoiding significant unnecessary treatment costs for the industry, and resulting in a better industrial pretreatment program for the City.
EEC provides an array of industrial pretreatment consulting services for wastewater agencies and private industries utilizing experienced engineers and chemists that are uniquely skilled in industrial wastewater issues. For agencies, EEC conducts local limits evaluations, develops industrial pretreatment ordinances and enforcement response plans, and assists in industrial user permitting. For industries, EEC designs and builds wastewater pretreatment systems and performs pretreatment system evaluations for flows up to 2.5 millions of gallons per day (MGD). EEC has unique expertise in developing technically based local limits and ensuring that industrial users have reasonable discharge permits.
EEC has also created and conducts an operator training program for industrial wastewater dischargers and assists industries in achieving compliance with their wastewater discharge requirements.
