REQUIREMENTS FOR DISCHARGERS WHO HAVE BEEN GRANTED AN
OCEAN PLAN EXCEPTION FOR DISCHARGES TO ASBS

quality in the affected ASBS. The ASBS Compliance Plan shall include a
description of appropriate non-structural controls and a time schedule to
implement structural controls (implementation schedule) to comply with these
special conditions for inclusion in the Discharger’s SWPPP.

3. By September 20, 2014, the Discharger shall submit the final ASBS Compliance
Plan, including a description and final schedule for structural controls based on
the results of runoff and receiving water monitoring.

4. By September 20, 2013, any non-structural controls that are necessary to comply
with these special conditions shall be implemented.

5. By March 20, 2018, any structural controls identified in the ASBS Compliance
Plan that are necessary to comply with these special conditions shall be
operational.

6. By March 20, 2018, all Dischargers must comply with the requirement that their
discharges into the affected ASBS maintain natural ocean water quality. If the
initial results of post-storm receiving water quality testing indicate levels higher
than the 85th percentile threshold of reference water quality data and the pre-
storm receiving water levels, then the Discharger must re-sample the receiving
water, pre- and post-storm. If after re-sampling the post-storm levels are still
higher than the 85th percentile threshold of reference water quality data, and the
pre-storm receiving water levels, for any constituent, then natural ocean water
quality is exceeded. See Flowchart at the end of this Attachment.

7. The Executive Director may only authorize additional time to comply with the
special conditions 5 and 6, above if good cause exists to do so. Good cause
means a physical impossibility or lack of funding

If a Discharger claims physical impossibility, it shall notify the Board in writing
within thirty (30) days of the date that the Discharger first knew of the event or
circumstance that caused or would cause it to fail to meet the deadline in 5. or 6.
The notice shall describe the reason for the noncompliance or anticipated
noncompliance and specifically refer to this Section of these requirements. It
shall describe the anticipated length of time the delay in compliance may persist,
the cause or causes of the delay as well as measures to minimize the impact of
the delay on water quality, the measures taken or to be taken by the Discharger
to prevent or minimize the delay, the schedule by which the measures will be
implemented, and the anticipated date of compliance. The Discharger shall
adopt all reasonable measures to avoid and minimize such delays and their
impact on water quality.

The Discharger may request an extension of time for compliance based on lack
of funding. The request for an extension shall require:
