Results of the bacteriological testing shall besatisfactory with the State Department of Health.

d. Release of water from structures and pipelines, aftertesting and disinfecting have been completed, shall be as directed by theDepartment.

2. Preliminary Cleaning and Flushing: Prior to both testing anddisinfecting, all hydraulic structures shall be cleaned by thoroughly hosingdown all surfaces with a high pressure hose and nozzle of sufficient size todeliver a minimum flow of 50 gpm; all pipelines shall be thoroughly flushedor blown out, as appropriate.

3. Testing and Disinfecting of Aeration Tower; The aerationtower shall be tested and disinfected simultaneously. The Contractor shallnotify the Department at least two working days before beginning the testingand disinfection of the aeration tower.

DIVISION Fll ' TESTING AND DISINFECTION

chlorination system with a chlorine feed rate sufficient to produce achlorine dose of 4 ppra. During the testing period no visible leakage shallbe allowed. If leakage occurs the Contractor shall repair the leaks to thesatisfaction of the Department. Afterwards, the aeration tower shall beretested and disinfected.

Mortar-lined pipingshall not be tested before the mortar lining has attained an age of 14 days.The test shall be made by closing valves when available, or by placingtemporary bulkheads in the pipe and filling the line slowly with water. Careshall be taken to see that all air vents are open during filling. After thepiping or section thereof has been filled, it shall be allowed to stand undera slight pressure for a sufficient length of time to allow the mortar liningto absorb what water it will and to allow the escape of air from any airpockets. During this period, bulkheads, valves, and connections shall beexamined for leaks. If any are found, corrective measures satisfactory tothe Department shall be taken. The test shall consist of holding the testpressure on the piping for a period of 4 hours for water tests and 3 hoursfor air tests. The test pressure shall be as shown on the standard PipingSchedule. Testing shall be performed with pipe joints exposed unlessotherwise permitted by the Engineer. All visible leaks shall be repaired asdirected by the Engineer.

Care shall be takento prevent the strong chlorine solution in the line being treated fromflowing back into the line supplying the water.

c. Retention Period; Chlorinated water shall be retained inthe pipeline long enough to destroy all non-spore-forming bacteria. Thisperiod shall be at least 24 hours. After the chlorine-treated water has been

MaximumEmissions

Compound (Ibs/day)

Total VOC's 2.0Benzene 0.02Chloroform . 0.51,1-Dichloroethene 0.2

Acceptance of the performance shall be determined byair phase samples taken by the Department after tvo weeks of continuousoperation and after sixty days of continuous operation. Samples will betaken at the air inlet to the blower and at the effluent of eachindividual contactor. These samples vill be analyzed at the Department'sexpense by a suitable laboratory chosen by the Department. The Contractormay take an additional set of samples for analysis at his discretion, atno cost to the Department.

In the event that the performance criteria is not metat either of the two sampling dates, the Contractor shall modify orreplace, at no cost to the Department, all or part of the emissionscontrol facility in order to meet the performance criteria.

b. Relative Humidity; Before air enters the activatedcarbon contactors, it shallBeheated to reduce the airstream relativehumidity to a typical operating relative humidity of 50 percent. Inaddition, the heater and its controls shall permit the Department toselect output relative humidities ranging from 40 to 100 percent. Theheating system and its controls are-further specified in Division F30.3.

Acceptance of performance shall be determined byrelative'humidity measurements taken by the Department after two weeks ofcontinuous operation. Test criteria shall be to reduce the airstreamrelative humidity to 40 percent and maintain it within between 36 and 44percent relative humidity for one hour.

In the event that the performance criteria is not met,the contractor shall modify or replace, at no cost to the Department, allor part of the heating system in order to produce an operating systemmeeting the performance criteria.

c. Carbon Changeout; In accordance with Division F27.3.a,the activiated carbon changeoutshall be required when any one or anycombination of the said emissions conditions are reached or exceeded. Theminimum activated carbon changeout period under the VOC input conditions

F27-3
