<br />3. Based on the mass balance evaluation, the following conclusions <br /> <br />relative to future point source water quality problems \'Iere established: <br /> <br />No DO problems from municipal discharGes are anticipated in the <br />Study Area. All minimum projected DO levels are substantially <br />above required standards. <br /> <br />With the exception of the Grand Junction area (which was not <br />evaluated) there are no perceived future NH~-N problems in the <br />Study Area. The future Mesa ~~TP may chang~ this conclusion for <br />Mesa and Plateau Creeks. <br /> <br />Based on a ratio of stream flow to waste discharge of 250:1, no <br />future residual chlorine problems are anticipated except below <br />Carbondale, Collbran, Rangely, and the Collbran Job Corps CamD. <br />The NPDES Permit system can be used to control chlorine discharges <br />at these locations. <br /> <br />4. Recently completed or ongoing 201 facilities plans in the Study <br />Area are the ultimate 208 program point source control plans for those <br /> <br />service areas. <br /> <br />5. iio local pretreatment or BAT standards have been establ ished for <br /> <br />industries in the Study At'ea. The 208 Program needs to decide if this is a <br /> <br />pri ority issue. <br /> <br />[,onpoi nt Source Controls <br />1. A variety of NPS management alternatives are available but the <br /> <br />selection of best mna<]ement practices Must be deferred until \'lOrk by the <br /> <br />OJAASCD/SCS is complete. <br /> <br />Institutions <br /> <br />1. The current institutions/agencies with water auality related resnon- <br /> <br />sibilities represent an overlapping, incomplete system of authorities with <br /> <br />regard to implementing a 208 Plan. This is partially due to each level of <br /> <br />government developing a separate body of law, policies, and procedures indi- <br /> <br />pendent of each other. <br /> <br />002999 <br /> <br />- 8 - <br />
