Synthetic Organic Chemical Manufacturing Industry - Wastewater - Subpart YYY

{This subpart has only been proposed.}

An affected facility is a designated chemical process unit (CPU) in the synthetic organic chemical manufacturing industry which generates a process wastewater stream, a maintenance wastewater stream, of an aqueous in-process stream and which commences or commenced construction, reconstruction or modification after September 12, 1994. {Regulates the VOC emissions.}

A designated CPU is all process lines with the primary product is a SOCMI chemical. Each storage vessel that is part of the CPU shall be assigned to one designated CPU that it services.

The following water and wastewater streams can be part of the affected facility but are not subject to NSPS Subpart A or YYY (per §60.770(h)(3)):
(1) Stormwater managed in segregated sewers.
(2) Water from fire-fighting and deluge systems in segregate sewers.
(3) Spills.
(4) Water from safety showers.
(5) Water from testing of deluge systems.
(6) Water from testing of firefighting systems.

Re-evaluation of applicability (not more than once every 12 months):
(1) Change (begins or ceases manufacturing) of chemical (s) used in the primary product determination -- Re-evaluate the primary product determination per §60.770(f).
(2) If designated CPU is modified or reconstructed.
