<br />x. Oil and Grease Monitorine
<br />For every outfall with oil and grease monitoring, in the event an oil sheen or floating oil is observed, a grab sample shall
<br />be collected, analyzed, and reported on the appropriate DMR. In addition, corrective action shall be taken immediately
<br />to mitigate the discharge of oil and grease. A description of the corrective action taken should be included with the
<br />DMA.
<br />Self-monitoring sampling by the permitlee for compliance with the monitoring requirements specified above shall be
<br />performed at the following locations: Outfalls 002, 003, 004, 005, 006, 008, 009, 010, 011, 0 ] 2, 013, 014, 0 ] 5, 016 and 017
<br />at the outfalls oC the sedimentation ponds prior to entering the immediate receiving waters.
<br />If the petutittee, using the approved analytical methods, monitors any parameter more frequently than required by [his permit,
<br />then the results of such monitoring shall be included in the calculation and reporting of the values required in the Discharge
<br />Monitoring Report Form (DMRs) or other forms as required by the Division. Such increased frequency shall also be
<br />indicated.
<br />Monitoring Exemptions:
<br />For Outfalls 004, 005, 008, 009, O1 L, O14, 015, 016 and 017, during the winter season, monitoring may be suspended at the
<br />pem~i[tee's option when adverse weather conditions prohibit safe access [o one or more of these discharge points a[ the
<br />• frequencies specified in this subpart. Monitoring shall recommence at the first opportunity after such inaccessibility ends.
<br />When inaccessibility prevents sample collection, the permit[ee shat] document what monitoring was missed and the specific
<br />conditions- that prevented access in cover letters [o the appropriate Discharge Monitoring Reports. For Outfalls 002, 003,
<br />004, 005, 006, 008, 010, 011, 012, 073, 014, 016 and 017, the permittee is exempted from the chronic WET testing frequency
<br />of 3 grabs/test if effluent discharges cease before the end of the monitorin, period (see Par? LA.6.a). For Outfalis 013, 014
<br />and 017, weekly monitoring for pH and flow may be exempted, based upon demonstration of inaccessibility.
