The 2010 RGP has been administratively continued and will be superseded following the effective date of the RGP reissuance.

The following changes were made to the 2010 RGP during the permit term:

  • Appendix III - The effluent limit for Benzene was omitted. The effluent limit for benzene in 5 µg/l.
