<br />1. Frequencv and Sumple'f
<br />In order to obtain an indtcanon of the probable compliance or noncompliance with the effluent limitations specified in Pan
<br />LA.1, the permiuee shall momtur all effluent parameters at the following frequencies. Such monitoring will begin
<br />immediately and last for the Itfc of the permit unless otherwise noted. The results of such monitoring shall be reported on
<br />the Discharge M1lonitonng Report (See Part LE.I.). Also see Pan LB. I.c. for Total Dissolved Solids (TDS) monitoring
<br />requirements.
<br />Winter Monitoring Exemption: For outfalls 004, 00~, 008, 009, 011, Old, 015, 016 and OI7, dunng the winter season.
<br />monitoring may be suspended at the permittee's option when adverse weather conditions prohibit safe access to one or
<br />more of these discharge pomts at the frequencies specified in this subpart. Monitoring shall recommence at the first
<br />oppor[uniry after such inaccessibility ends. When inaccessibility prevents sample collection, the permiuee shall document
<br />what monitoring was missed and the specific conditions that prevented access in cover letters to the appropriate Discharge
<br />M1lonitoring Reports. Whole El Fluent Tonicity testing for outfalls 004 and 008 is exempted completely for the first calendar
<br />quarter and is included in this enemption beyond the first quarter when inaccessibility is documented as described herein.
