EPA Notice of Proposed NPDES General Permit Reissuance
|
Published on June 30, 2004
Region 6 proposes to reissue the NPDES general permit for the Western Portion of the
OCS (No. GMG290000). The following changes to the expiring permit are proposed to
be made:
The time frame is specified for collection of a produced water sample after a
sheen is observed.
The discharge prohibitions at National Marine Sanctuaries are clarified in an
attempt to better reflect NOAA regulations.
The variability factor for use in determining compliance with the permit's limits for
sediment toxicity and biodegradation is removed.
The requirement to submit fourteen day advanced notification of intent to be
covered by the permit is removed.
The final discharge monitoring report will be required to be submitted along with
the a notice of termination.
New test methods are allowed for monitoring cadmium and mercury in stock
barite.
Several minor miscellaneous discharges are added to better represent deep
water technologies.
Miscellaneous discharge requirements are proposed to clarify that toxicity testing
is not required for non-toxic dyes.
EPA is proposing that the permit be reissued for three years. During the three year
permit term, EPA and MMS propose to conduct a study to collect additional information
to support the evaluation of potential produced water discharge impacts in the hypoxic
zone in the northern Gulf of Mexico. EPA and MMS will work in partnership to determine
the appropriate next steps based on this study.
