Nuel, <br /> I'm confused on WHO is calling the shots on the ozone at this site. <br /> For ISCO, Jim and his WDR concerns trump our LOP lead stuff. Under his NOI and <br /> WDR requirements, if problems (precipitates) occur, then he requires a contingency <br /> plan enactment; typically, turn it off. <br /> I don't see I/the EHD has the authority to have the RP turn the ISCO back on when the <br /> 'problem' may, or still be present.... <br /> JLB's response here confuses me. Do I/the EHD have authority to turn the ISCO back <br /> on with the precipitate concern still/possibly present? <br /> I would like a Fourth Quarter 2011 gw sampling event for Mn to verify if it's attenuating. <br /> Your thoughts? <br /> mike <br /> -----Original Message----- <br /> From: Jim Barton [mailto:jbarton@waterboards.ca.gov] <br /> Sent: Thursday, November 17, 2011 2:25 PM <br /> To: Mike Infurna [EH] <br /> Cc: Nuel Henderson [EH] <br /> Subject: Re: Mn sampling at ozone site <br /> Mike, <br /> I'd tell them to restart the ozone sparging system and see what happens while it's <br /> running. Mn should have been decreasing by September 2011 , not increasing if the <br /> ozone was causing it. If it were my case... <br /> Jim <br /> James L.L.
