I have to go back deep into my reference material to find it. I believe <br />some of that material was provided by Mike Kith and Steven Shih. I am really busy this week and <br />won't get to it until the end of next week. So instead I revised the calculations with no nitrogen <br />reduction. I used 45 for residential and 85 for the industrial and the total was 9.19. The revised pages <br />are attached. Let's just go with this. It's the most conservative and it passes, so may as well. <br />Thoughts? <br />Thanks, <br />Brian Millman <br />Senior Geologist <br />CA Professional Geologist No. 8574 <br />OR Registered Geologist No. G2663 <br />CA QSP/QSD No. 26882 <br />AdvancedGeo, Inc. <br />Environmental • Compliance • Industrial Hygiene • Geotechnical <br />Phone: 800-511-9300 <br />Fax: 888-445-8786 <br />bmillman(a-)-advancedgeo.biz <br />www.advancedgeo.biz <br />"Working in Partnership with People, Business and the Environment" <br />This email/fax message is for the sole use of the intended recipient(s) and may contain confidential and privileged information. <br />Any unauthorized review, use, disclosure or distribution of this email/fax is prohibited.

In <br />the mass balance of nitrogen loading section you make a claim that 15% of total nitrogen concentration is reduce in the <br />septic tank, I agree, but could you provide a source or reference to this claim or explain how the concentration is <br />reduced by 15%? <br />
