EPA Drops Wastewater Blending Proposal

摘要

The House of Representatives voted in May to block the Environmental Protection Agency (EPA) from issuing its wastewater blending proposal, which would have allowed sewer operators to discharge partially treated sewage into waterways. To handle excess flows during heavy rains or snowmelts, sewage plant operators sometimes treat all wastewater with the primary clarifier, then route the volumes that exceed the capacity of the plant's biological treatment unit directly into the discharge from the unit.
