I-1 6 In the lengthy discussion that ensued , Mr . Jenks clarified the basic three levels of treatment , i . e . , primary , secondary and tertiary . He reiterated that the Federal Government had mandated that all wastewater treatment plants in the United States that received Federal grants would have to have at least a minimum of full " secondary " treatment . With respect to Redwood City , San Carlos , and Belmont , it was noted they had a treatment that would come in between the primary and secondary treatment , a partial secondary , and would be required to go to the full secondary treatment - 85 to 90% removal of glutinous material - which at the present time about 70% is being removed . Mr . Jenks proceeded to highlight the chapters in the report submitted that reflected upon Redwood City . He commented on the fact that not only would the long- range water quality objectives , requirements and the current and anticipated needs be of a concern to protect and enhance the quality of the receiving water environment , but also taking into account the important objectives relating to , --- a reliability , ( b ) flexibility , ( c ) reclamation , ( d ) regional planning , e environmental impact , and ( f ) cost effectiveness would have to be considered in order to meet State and Federal Government requirements and objectives . He noted that the recommended San Mateo County Water Quality Management Program Stage I provides for treating all County wastewater prior to discharge to at least full " secondary " level , plus filtration for central and south Bayside dis - chargers . Strategic consolidations within four of six Study System Units of treatment and disposal facilities as part of the Program Stage I would result in a three point central Bay disposal system , with a corresponding three point Ocean disposal system , with added flexibility enhancing the prospects for reclamation and beneficial reuse . There was discussion of the cost of the recommended Program Stage I facilities , assuming escalation to 1975/76 dollar value would be about $50 , 000 , 000 , of which amount up to 874% could be funded by State and Federal grants , leaving a total of some $6 , 100 , 000 of local monies needed to implement the Program . It was noted that the recommended San Mateo County Water Quality Management Program had been developed consistent with both established and anticipated water quality objectives and requirements . The Program was considered to have optimized achieving important additional objectives , both economic and non- economic and environmental . The Program would provide the means whereby San Mateo County wastewater dischargers effectively could build upon past efforts towards a clean water environment . Oxidation Ponds were discussed in some length , noting that although there would be no resultant discharge from the ponding system , since the wastewater is afforded secondary treatment by aerated oxidation , the only apparent limitation w ould be in how big and how many ponds the area would have to have . It would appear that the limitation of land was what essentially led away from the oxida- tion pond method of treatment , which had been used throughout the Country , to other means of manufactured sewage disposal . Mr . Dowd gave a brief rundown on the land use and population projections and referred to Chapter Four , Figure 4 - 1 , " Comparison of County Population Projections , " of the report presented . City Manager spoke to the State Water Resources Control Board adopted regulations which specified , "Population fore - casts for planning basins within critical air areas shall be based on ' Series E ' fertility and 0 net in--migration " . It was noted that this regulation would be directly applicable to San Mateo County inasmuch as the County was within a designated critical air basin . It was brought to Council ' s attention that the significance of the regulation was primarily related to the limitation of State and Federal grant approval for financing of wastewater treatment and disposal facilities . He noted that the State , under these new regulations , would not approve grants for wastewater treatment and disposal facility capacity beyond that needed to serve future population within the " Series E " growth projections . This regula - tion would be of importance to the planning, particularly the financial planning as well as physical facility planning , of the San Mateo County Water Quality -_ Management Program . The State ' s "Series E " projections would result in a net increase of approximately 28 , 000 in the total County population between 1970 and 1990 ; and a decrease of approximately 8 , 000 between 1990 and 2000 . The assump - tions utilized in redistributing the population using the " Series Et' projections throughout the County were as follows : 1 ) Populations within the urbanized areas of the County would experience little or no growth between 1970 and 1990 , and w ould decline after 1990 . 2 ) The bulk of all increases in population would occur w ithin the coastside of the County and the planned communities of Foster City and Redwood Shores . It was emphasized that the low or "Series E " projections would be used by the State for establishing the eligibility of facilities for grants in the future . This did not imply that various areas would not experience higher rates of growth in the future ; however , if facilities were designed for capacity in excess of the low projections there would be a very serious impact in terms of the local costs which would be incurred , especially if planning was done at the local level , and the set standards were exceeded . 9/18/73 Adj .
