## Description

Regulation of treated wastewater discharges by the water industry is underpinned by control of ammonia and BOD via limits in Environmental Permitting Regulations \(EPR\) Water Discharge Activity Permits\. We have established an industry standard or technologically achievable limit \(TAL\) for these two parameters that we would not set a permit limit below\. However, these TAL limits were established more than a decade ago and it is appropriate to review them at regular intervals\. This project is to carry out these reviews\. Additional information: To apply please respond to the attached Request for Quotation and associated documents\. Email your response to richard\.bourne@environment-agency\.gov\.uk\. Tenders to be received no later than 09:00 on January 3rd 2023\.
