9 <br /> E. Collect and analyze samples once per year at 10 intake sites for most of USEPA <br /> Phase II and Phase V regulated constituents. <br /> This expands the number of constituents monitored at intake areas and focuses the <br /> project on those 64 constituents EPA has designated as most important(or of most <br /> concern)in drinking water. An additional 122 compounds will be monitored in the <br /> categories of volatile organics, acid/base/neutral extractable compounds; chlorinated <br /> pesticides;chlorophenoxy acid herbicides; triazine herbicides; and carbamate <br /> pesticides. <br /> F. Collect samples for GC/FID analysis once per three years at each (USGS and DEW <br /> non-intake site. GC/FID does not identify specific compounds but determines the <br /> relative abundance of methylene chloride extractable compounds and shows patterns of <br /> hits. Samples with significant detections of these compounds will be analyzed by <br /> GC/MS and will include a library search. (year 3) <br /> This is a reduction in scanning from 3 times per year to once every three years. <br /> Since the GC/FID scans detected little during Phase I and II,the Steering Committee <br /> recommends shifting most of the GC/FID funds into monitoring the Phase II and <br /> Phase V constituents at intake sites. However,it recommends maintaining a general <br /> watershed scan every three years. <br /> G. Sample selected sites(6 sites) 2 times per year each during a storm event for major <br /> ions, nutrients, and trace metals. (year 1,2, and 3) <br /> During Phase II,the Project conducted special storm event monitoring at 6 sites and <br /> monitored one half of the remaining sites once during high flows. The Project will <br /> evaluate sites each year during phase III to determine where it needs high flow data. <br /> This data will enhance the Project's pollutant loading analysis. <br /> H.Add/maintain one continuous streamflow gauge(Swift Creek)to the existing 12 <br /> gauges. (year 1, 2, 3, 4) <br /> This will enhance the Project's pollutant loading analysis. <br /> I.Discontinue all project monitoring at the Smithfield site on the Neuse River. <br /> Discontinue all project monitoring at Falls Lake at NC50 and NC98, and Lake Benson. <br /> The Town of Smithfield is not participating in Phase III of the Project. <br /> J. Develop annual project summaries(year 1,2,and 3)and an interpretive report. <br /> (year 4) <br /> K.Reduce project cost by a minimum of 7.7%in FY95-FY98 &by 5%in FY98-99. <br /> The phase III local cost in Attachment D reduces project cost by 7.7%;reduces the <br /> City of Raleigh's share by$13,416 annually(or more than 12%); and holds other <br /> local costs constant with phase U. In FY 95/96,the Project Steering Committee will <br /> continue to evaluate the effectiveness of alternative sampling plans and funding <br /> mechanisms for achieving project objectives while minimizing project cost. <br />
