Notes: (Include in the case of continuous monitoring) In the event of equipment failure or loss, the permittee must notify DEQ and deploy new equipment to minimize interruption of data collection. If new equipment cannot be immediately deployed, Permittee must monitor grab measurements daily between XX pm and XX pm until continuous monitoring equipment is redeployed. Percent Removal shall be calculated on a monthly basis using the following formula: . Where: Influent Concentration = Corresponding 30-Day average influent concentration based on the analytical results of the reporting period. Effluent Concentration = Corresponding 30-Day average effluent concentration based on the analytical results of the reporting period. Insert for systems where preliminary treatment occurs in septic tanks and influent sampling occurs after this preliminary treatment, such as STEP systems: The influent BOD5 or CBOD5 and TSS concentrations are assumed to be 200 mg/l for calculation of the percent removal efficiency.
