November 27. 1979. at 7:20 p.m. with the following City staff prosent: Terry Jennings Paul Rettig Sue Lamkin Engineering Department Utilities Director Assistant City Clerk Also present: John Dennis Briley, Wild and Associates Terry Jennings called the meeting to order and announced the purpose of this hearing is to solicit citizens comments and questions. There were no citizens present. John Dennis presented a written report included herewith in its entirety. "This"Pub1ic Hearing is being held in accordance with the requirements of the Water Pollution Control Act Amendments of 1972 (Public Law 92~SOO), and amendments stated in the Federal Register, Yolo 44, No. 34, dated February 16, 1979. The Public Hearing was advertised on October 12, 1979, in the Clearwater Sun, and its purpose is to solicit citizens comments and questions concerning the proposed projects. A record of this Public Hearing will be made a part of the City of Clearwater Applications for 75% Grant Assistance for the construction (Step 3) of proposed wastewater projects. All of the proposed projects are in conformance with the Central Pinellas County 201 Facilities Plan and have no impact on the ultimate system of effluent disposal. The following pro- jects are recommended for construction at this time, and applica- tions have been submitted for Federal Grant assistance. 1. Northeast/East Interconnecting Force ~fain and Alligator Creek Force Main. 2. Alligator Creek Pump Station. 3. Sunset Point Pump Station. 4. Curlew Road Pump Station. S. Bayfront Pump Station. Background The following background information is given in order for the public to fully understand the status of the waste'~ater sys- tem in Clearwater and the reasons for scheduling a Public Hearing at this time on the above named projects. ' In 1972, a Water Quality Management Plan for the Tampa Bay Basin was developed by the Tampa Bay Regional Planni~g Council (l'TBRPCfI), which included the upgrading and expansion of the Marshall Street Pollution Control Facility and the construction of the, new Northeast Facility as regional wastewater treatment systems. The first phase of the expansion and upgrading of the Marshall Street Facility was to a 10 mgd treatment plant, with facilities for nitrification of ammonia and phosphorous removal. Construction commenced in 1974. The new facilities' were placed into operation in August, 1978. The second phase of the program, "consisting of denitrification and filtratio~ was scheduled to begin in 1977. However, the U.S. Environmental Protection Agency recommended a delay pending completion of the 201 Facilities Plan to determine the most cost-effective method of treatment and effluent disposal. ' "",'" . . '....... The' design of the Northeast Regional Facility was started in early 1974 with design based on recommendation of the Water Quality Management Plan prepared by TBRPC. The Northeast Pacil~ lty was originally designed with a capacity of 8 mgd secondary treatment to serve the northeast area of Clearwater and Safety Harbor, and 16 mgd advanced wastewater treatment with discharge of effluent into upper Tampa Bay. The additional advanced wastewater treatment capacity 'was to be constructed to provide advanced wastewater treatment of secondary effluent from the Bast Treatment Plant and part of the City of Dunedin. Because of the delay in obtaining Federal Grants, the City, without Federal funds, constructed an interim 1 mgd secondary treatment plant with effluent disposal by an underdrained spray irriga~ tion field constructed on City property which was placed in operation in 1975. In mid-1975, the City, with plans for the advanced waste~ water treatment facility, essentially complete, was advised by BPA that effluent disposal by deep well' injection would have to be considered as an alternative to advanced wastewater treat- ment. In November 1975, an environmental assessment for the Northeast Facility was prepared, comparing the cost effectiveness of each of several alternatives for treatment and disposal of effluent. The results of this study indicated that the most cost effective alternative for effluent disposal was by deep well injection. provided that such disposal method could be determined to be both feasible and environmentally acceptable. As a result of this study, the City obtained a Grant offer from EPA in the amount of $5,775,000.00 to construct a new treatment facility with secondary treatment capabilities only. since secondary treatment would be required for any of the alternative methods of effluent disposal. At the same time, the City re- ceived a Step 1 Planning Grant to select a test site and con- struct one test injection well and appurtenant monitoring facil- ities in order to perform an intensive investigation of effluent disposal by deep well injection. At that time, it was projected that test well studies could be completed and the injection well could be in operation by the time the new Northeast Facility was operational. In early 1976, a contract was awarded for the construction of the new Northeast Facility. A site report for the deep well test was prepared, which recommended the con- struction of a test injection well and monitoring facilities at the site of the East Treatment Plant at Courtney-Campbell Cause- way in Clearwater. Plans and specifications for the construc- tion of the facility were prepared and submitted to the Depart- ment of Environmental Regulation and the Environmental Protec- tion Agency in Aguust, 1977. However, due to the number of agencies involved in the review and approval of plans and specifications, and changes in the design required by BPA, the project was not advertised for bid until May 1, 1978. Bids were taken on the project in July, 1978, and the contract was tentatively awarded by the City Commission in August 1978 pending approval by EPA. After EPA approval, final award of the contract was made on October 19, 1978, and work commenced at' the site in January, 1979. The City of Clearwater also cooperated with Pinellas County, DER and BPA in a long-range study for planning and implementation of sanitary sewerage systems through development of a Central Pinellas County 201 Facilities Plan. The purpose of a 201 Facilities Plan is to determine the most cost-effective waste- water transmission treatment and disposal system for the desig- nated planning area. The system must meet the needs of the area for 20 years and must have the least adverse environmental impact on the area for that time period. Work on the facilities plan was begun in late 1977, and a final draft of the report ,was.5ubmi~ted to the Department of Environmental Regulation and BPA in .l\pril, :Ll978.

Since the gulf, outfall is the recommended method of effluent disposal for treatment plants in Dunedin, Tarpon Springs and North Pinel1as County, as was recommended in the 201'Faci11ties Plan for that area, the BPA has initiated a site specific environmental impact statement for this outfall. However, it is not anticipated that the study will be completed before March, 1982. In July, 1979, the BPA terminated the deep well investi- gation project on the basis that findings did not sufficiently demonstrate the existence of suitable rock strata to prevent the upward migration of proposed injected effluent. Since deep well injection of effluent is no longer a viable disposal option, and effluent disposal through an outfall into the Gulf of Mexico is dependant on the out come of the Environmental Impact Statement, it is not possible at this time for the City of Clearwater to design and implement a final method of effluent disposal. The new Northeast Plant was placed into operation in October, 1979, and effluent is presently being disposed of by spray irrigation on City owned land. The City was granted a variance by the Department of Environmental Regulation in May, 1979, to temporarily discharge excess secondary effluent from the Northeast Plant through a local creek to upper Tampa Bay. The variance is allowed for a period of two years. After that time, it is anticipated that the variance will be extended with effluent being discharged through the Northeast/East Interconnecting Force Main, and the existing East Plant outfall into lower Tampa Bay until such time as the final method of effluent disposal can be designed and implemented. Under normal conditions, projects which are proposed in the 201 Facilities Plan, would be aired at a Public Hearing, which would be held to review the entire Facilities Plan. Such a Public Hearing will not be scheduled until BPA deter~ mines l~hether the existing final draft will be updated, based on the termination of the deep well study, or wait until the Environmental Impact Statement on the gulf outfall is completed. The projects proposed do not involve treatment and are not affected by the ultimate final method of effluent disposal. Therefore, in order to obtain grants at this time for these much needed facilities, EPA recommended that a separate Public Hearing be held for these facilities. Descriptions of the pro- posed work are as follows: Northeast/East Interconnectin Force Main and AlIi 'atorCr'eek Force aln These two projects would be let as a single contract since they follow the same alignment. The Northeast/East Interconnect- ing Force Main will be used for any alternative of effluent dis- posal including spray irrigation. It will transfer secondary effluent from the East Plant to the Northeast Facility for transmission to the gulf outfalt for advanced wastewater treat~ ment, or for spr~y irrigation. The approximate route of this 25,500 foot pipeline is as shown on Exhibit 1 and will be con- structed from the Northeast Plant, south along McMullen Booth Rd. to Drew Street, east to Bayshore Drive and then south to the Bast Treatment Plant. The Alligator Creek Force ~Iain will divert the flow from the large area shown on Exhibit 1, to the new Northeast Facility. The force main will parallel the route of the North~ast/East Interconnecting Force Main from Alligator "Creek to the Northeast Plant. The approximate cost of both projects is $4,170,000.00. In order to ex~edite construction " " o,f this ,proj ect, the Environmental Protect1on Agency has agreed ,",..~,.,...:,..:".to:finance 75\ of the cost,as an increase to the current, ,~'Jt~~(l.:j:;~//.'.:~ ':::J~o~theast ,:Treatment Facili ty ~rant. .

The Alligator Creek Pump Station will be constructed to pump the flows from the North Interceptor, as shown on Exhibit 1, through the Alligator Creek Force Main to the Northeast Facility for treatment. The station capacity is 6700 gpm and the approximate cost is $600,000.00. This project will also be funded as an increase to the current Northeast Treatment Facility Grant. The pump station will be constructed on the west side of McMullen Booth Road on land which has been pro- cured by the City of Clearwater. A rendering of the proposed pump station is shown on Exhibit 2. Sunset Point Road Pump Stati'on 'and 'For'ce Main The Sunset Point Road Pump Station and Force Main will pump flows collected from the northwest section of Clearwater, as shown on Exhibit 1, directly to the Marshall Street Treat- ment Facility and will provide relief for the presently over- loaded, gravity sewerage system.. The station will be located on the south side of Sunset Point Road. A rendering of the proposed station, is shown on Exhibit 3. The station will pump a peak flow of approximately 3500 gpm and the approximate cost is $740,000.00. Curlew Road Pump Station This pump station will pump wastewater flows from the north- east section of Clearwater, area shown on Exhibit 1, to the Northeast Treatment Facility. A rendering of the proposed sta- tion is shown on Exhibit 4, and the approximate cost is $500,000.00. The contract for the construction of the force main portion of this project and a temporary pump station has 'been awarded by the City Commission. Bayfront Pump Station The existing Bayfront Pump Station was constructed in 1973 to convey wastewater flows to the Marshall Street Facility from the entire beach area, including flows previously treated by the Marina Station Wastewater Treatment Facility, plus a large ~ec~ tion of the downtown area. The site of the original pump station was chosen so as not to interfere with the then existing audito~ rium facilities and the proposed loop connection to the beach. Because space was limited and the site was located directly on the City's bayfront, the station was made as small as possible with no superstructure so as to create a low profile. Th~ equipment included two pumps, each capable of pumping the peak flow from the service area and a comminutor to grind rags and small debris. The City's total investment in the station was approximately $100,000.00. Since being placed into operation, the station has suffered frequent power outages and over-voltage conditions which have damaged electrical equipment in the station and produced conditions where it would be possible for both pumps to be out of operation simultaneously, even though 100% stand-by capacity had been provided. Although comminutors, which grind rags and small debr:j.s have worked:,s atiafactorily in the City I S treatment plants, the comminutor equipment at the Bayfront Pump Station has not been able to handle the materials dis- charged from hospitals and other downtown tributary' facilities. In addition, hydrogen sulfide build-up in the long force mains on the beach area has produced odors and resulted in deteriora- tion of equipment in the wet well area of the station. Studies were made to determine the most cost-effective method of rehabil~ itation of the station and adding the equipment required to ,upgrade the facility to satisfactorily handle the material being : discharged into it. It was determined th~t additional smaller pumps should be provided because of the problems associated with' the' incoming power supply. In addition, because of the materials . ; tributary to' the' pump station ~n the wastewater, mechanica~lr :. ." "'~' ';.' :, cleaned screens should be provlded to remove rags and debrls. :,~>::..:~ ,'(::,:,.,\;':;', H,ow.ev~r" a. superstructure is required to install this type of ~X.,fji':~;::'.~;:::,~;~~:'~:},"~<e,q~'~~m~~t'." ."It, would ~ot be practical or economical to install ~~if:~~Wt4dl~iAji~t;;;;J;I~~;x';r,ii~;.;;,;.'d;, < '" '",. i( ~'~I>~".$'''''1'.t~(\''':'y:t.\~l';'''''~I)...,."t~.~;~.,..'o-~'\~~'''''''''' ~4 '.~~.". ..w~' >~ .~'i~"'1it,,~~i :J1t:,~tt~:rJi'!-!lJ~!l.~.:t{;~\{~il~.'t..~~/.~~.;~~: ':,'.~/': ., ;,::q'~'~. .r'...~>~ \:.~.,:l~~' : r.'
