Limitations to be determined by Regional Board staff upon review of each submitted Report of <br /> Waste,Discharge. Appropriate limitations will be set in the Executive Officer's"Notice of Applicability"letter. <br /> Note:1)Constituent quantitation(or reporting) limits are to be sufficient to identify a violation to the above <br /> listed effluent limits and/or those specified in the applicable"Notice of Applicability"issued by the <br /> Fxccutive Officer. <br /> 2)All detection and quantitation limits must be reported with the analytical results. <br /> 3)Published literature for Total Petroleum Hydrocarbons as gasoline provides a taste and odor threshold <br /> of 5 ugA which is applied to the narrative Taste and Odor objective of the Basin Plan,but detection is <br /> 50µg/1 and is controlling. <br /> 2. The discharge of lead must comply with the above listed Iimitation unless the <br /> Discharger can demonstrate that higher concentrations are a result of naturally <br /> occurring background concentrations contained in the source water being treated. <br /> Background concentrations may be defined by using the methodology described in <br /> Title 27 CCR Section 20415. <br /> 3. The discharge shall not have a pH of less than 6.5 nor greater than 8.5. <br /> 4. The discharge shall remain within the designated disposal area at all times. <br /> D.
