Maximum Permissible Discharge (MPD) projects

Maximum Permissible Discharge (MPD) is a limit of permissible mass of pollutant in waste waters in unit time. It is established to provide legally permissible water quality on particular control points.

MPD project contains norms and requirements for return waters disposal and other activities, which can have negative impact on underground and surface waters’ condition.

MPD project development is legally required for all companies, which perform water disposal into water bodies. MPD limit should be established for every pollutant for each effluent discharge outlet and a facility in general.

MPD project includes:

• introduction;
• general information about the company, its major activities and structure,
• characteristic of contemporary water body conditions,
• characteristic of a facility as a pollution source,
• MPD calculations,
• processing, storage and usage of waste waters remains (if facility is equipped with effluent treatment plant),
• suggestions for emergency discharge prevention,
• MPD limits control,
• detailed scheme of water consumption and discharge and MPD calculation

MPD project procedures:

• identification of a water body,
• determination of discharge outlets,
• calculations of annual waste waters’ volume,
• determination of actual discharge volume,
• execution of quantitative chemical analysis of waste waters’ pollution by certified laboratory,
• calculation of preliminary approved discharge (PAD)
• development of measures for minimizing sewage waters negative impact on environment,
• development of detailed plan for MPD limits achieving,
• MPD limits approval by authorities concerned,
• obtaining water permit,
• obtaining and approving discharge permit in Federal Service for Supervision of Natural Resource Usage.

Period of validity  of MPD projects is 5 years (in case of stable implementation conditions).

Possessing wide experience DIEM specialist provide the full range of works on MPD project development and approval.
