CO 0026620 City and County of Denver Denver, Colorado Dear Sirs: Pursuant to the provisions of federal and state regulations, acting in my capacity as District Attorney for the Seventeenth Judicial District, County of Adams, State of Colorado, I make de- mand for a public hearing concerning the application of the City and County -of Denver for a sewage discharge permit, proposed draft dated April 4, 1975. I am statutorily obligated to enforce the public health laws , specifically the Colorado Water Quality Control Act, in the Seventeenth Judicial District in Adams County. The state Act defines a pollutant as "sewage and sewage sludge" (C.R.S . 1973 , §25-8-103 (11) . The City and County of Denver has applied for a permit to dis- charge raw sewage into the mainstream of the South Platte River. The South Platte River flows from the City and County of Denver through Adams County. The introduction of untreated sewage into the South Platte River by the City and County of Denver constitutes an extreme health hazard. The water of this river is used by the public for domestic, agricultural, and other consumptive uses. U. S. Environmental Protection Agency Colorado Department of Public Health Re: NPDES PERMIT NO. CO 0026620 City and County of Denver Denver, Colorado May 1, 1975 Page Two Raw or inadequately treated sewage carries infectious organisms. This material is readily transferable by domestic animals, insects, or direct contact. The presence of this raw or inadequately treated sewage in the river and its outgoing tributaries , such as irrigation ditches, readily disseminates this contaminated material - to the community. It is highly probable that the produce of truck farms irrigated with river water would be contaminated and this contamination be carried to the general communities through the sale of these products. Disease organisms which are normally found in raw or inadequately treated sewage include salmonellas (more particularly, typhoid, para-typhoid, etc. ) , amoebic dysentery, and bacilliary dysentery. If the City and County of Denver disposes ra*d or inadequately treated sewage, there will be a time lag of approximately five days before the fact of such discharge could be confirmed by laboratory analysis because of the necessary laboratory procedures. This delay will increase the likelihood of the outbreak of epidemics. Upon the confirmed discharge of raw or inadequately treated sewage, and because of the low flow of the river at particular times of such discharges, the dilution factor would be minimal and would result in a high concentration of said disease organisms. The raw or inadequately treated sewage will create irreparable damage to fish in the South Platte River and wildlife in its immediate sur- roundings. Dumpage during periods of low flow of the South Platte River will cause a persistent odor problem along the river and its outgoing tributaries. Not only is such a discharge of untreated sewage hazardous to public health, but also such a discharge would be in direct vio- lation of C.R.S . 1973, X25-8-503 (4) , which states: "No discharge shall be permitted that by itself or in combination with other pollution, will result in the pollution of the receiving waters in excess of the pollution permitted by applicable water quality standards unless the permit contains affluent limitations and a schedule of compliance specifying treatment requirements" . • U. S. Environmental Protection Agency Colorado Department of Public Health Re: NPDES PERMIT NO. CO 0026620 City and County of Denver Denver, Colorado May 1, 1975 Page Three Because a discharge such as that which Denver seeks to legitimize by permit is a health hazard, and because the issuance of such a permit would be in direct violation of statutory provisions, no permit should issue. I strongly urge the denial of the application for this permit for Denver. If, however, the permit is to issue, a public hearing is imperative to bring under public scrutiny the restrictions upon discharge of raw sewage by Denver. The proposed permit in its present form is inadequate in numerous respects, in particular, the provision for limitation upon the quantity of discharge and • the scheduling of discharge should be more stringent. Neither the fact sheet nor the provision of the permit adequately justify the need for 12 discharge points. As minimal a number of discharge points as possible should be authorized. This will facilitate stricter monitoring and enforcement of specified requirements and will assure compliance by the City and County of Denver with the terms of the permit. { Other restrictions and limitations on the permit which should be reviewed concern notice of accidental discharge, the removal and/or repair of cross-connections between sewage systems and storm drainage systems, the repair of antiquated equipment that results in leakage of any raw sewage in excess of that authorized by the permit, and provisions for more stringent monitoring by an indepen- dent agency. Lastly, a public hearing is essential to inform the public of the present health hazard engendered by .Denver' s policy of discharging raw sewage into the South Platte River. The records of the U. S. Environmental Protection Agency, the Tri-County Health Department, and the State Health Department, all reflect the fact that the City and County of Denver has been and, in fact, is now discharging raw sewage into the river. On July 29 , 1974, raw sewage affluent was discharged by the City and County of Denver into the South Platte River between the hours of 5 : 00 p.m. and 7:00 p.m. That point of discharge is identified in the proposed permit as Source 006 , more commonly known as the intersection of 31st Avenue, Arkin Court, and the South Platter River. Nor is this July 29th inci- dent an isolated one. All 12 proposed source points have discharged from overflows at times of moderate precipitation. Three of these • U. S. Environmental Protection Agency Colorado Department of Public Health Re: NUDES PER_ IT NO. CO 0026620 City and County of Denver Denver, Colorado May 1, 1975 Page Four point sources , 004, 010 , and 011, regularly discharge raw sewage cn days of no precipitation. Initially, when the EPA was presented with Denver' s application for a permit, the EPA requested that Denver present a study of • alternatives to discharge of untreated sewage directly into the . river. In response to that request, Denver submitted three al- ternative short-term solutions. These alternatives were as costly and would require as much time to implement as proposed long-term solutions. It is probable that an independent, dis- interested agency would develop more realistic and economic al- ternatives. An investigation by such an independent agency should be required prior to the issuance of any permit. A plan known as "The Platte II Intercepter Project" has been de- signed to eliminate the discharge problem. The design for this project has been completed for several years. Originally, the EPA recommended that the Metropolitan Sewage District include The Platte II Intercepter Project in its plan for the funding and construction of the new Metropolitan Sewage District Treatment Plant. The EPA requested that Metro and Denver discuss and re- solve five areas of conflict concerning that new treatment plant. The most significant of these conflicts concerned the integration of The Platte II Intercepter Project into the Metropolitan system. Denver sought to incorporate The Platte II Intercepter Project into its municipal system rather than permit that intercepter to be integrated into the Metro system. Due to this jurisdic- tional conflict, Denver refused to cooperate with Metro to develop The Platte II Intercepter. ;No funding was obtained for the project, consequently, no project was started. The present overflow problem has resulted. Due to their refusal to cooperate, the municipal officers of Denver must bear the responsibility for the present discharge problem. 'The citizens of the state who live downstream from the discharge points are the potential victims of this irrespon- sible conduct. Circulation of the notice of the proposed permit by Denver was , minimal. Other interested governmental agencies should be given the opportunity to join in the demand for a public hearing on this U. S. Environmental Protection Agency Colorado Department of Public Health Re: NPDES PERMIT NO. CO 0026620 City and County of Denver Denver, Colorado May 1, 1975 Page Five matter. Pursuant to the rules of the EPA and the State Health Department, I request that the agency extend the time period within which such demands for a public hearing on the permit may be submitted, and that additional notification be sent to all interested parties downstream from the Denver discharge points. Yours very truly, I/ /M. 1 FM:c -lo Yd narks Hello
