Bradford Ranger District Office General Description: North Central Lagoon The Bradford Ranger District Office is located at 29 Forest Service Drive within the Allegheny National Forest. The Public Water System Name is “USDA Bradford Ranger Station” and the PWS ID is 6420303. This system has monthly, annual, and triennial monitoring requirements.

The North Central Lagoon Wastewater Treatment Facility (Facility) is located within the Allegheny Nation Forest, Corydon Township, McKean County, Pennsylvania. Specifically, the Facility is located adjacent to the Bradford Ranger Station/Administrative Site (Bradford Station), on the southwest corner of the intersection of PA Routes 59 and 321, approximately 15 miles west of Bradford, PA.

The Facility was originally constructed in 1976 to treat and dispose of two primary sources of sewage flow:

1. Sewage collected from various vault toilets and holding tanks located throughout the Allegheny National Forest recreation areas, and

2. Sewage pumped directly from the Bradford Station.

The North Central Lagoon wastewater treatment facility includes a receiving pit with coarse bar screen, a comminutor, a primary aeration lagoon, a chlorine contact tank, a holding pond, a spray irrigation pump, and a spray irrigation field. The facility also contains a small control building which houses electrical and pump controls, chemicals, and a hydro-pneumatic water tank. A duplex grinder pump station is located off-site to pump sewage from the Bradford Ranger Station to the Facility.

The system is operational year-round, spraying is permitted between March 15 and November 15. During the winter months, the Facility acts as a large holding pond. The water level in the lagoon is pumped down in the late fall, and sewage from the Bradford Station slowly fills the lagoon over the winter. No vault sewage is delivered to the Facility during this time, and no spray irrigation occurs throughout the winter.

Typical operations include adjusting control timers for proper aeration, setting irrigation pumping cycles, testing effluent to determine suitability for spraying, screening and grinding incoming truckloads of waste, and general recordkeeping. Maintenance includes cleaning and maintaining equipment, yard piping, and structures as well as general cleanliness and landscaping of the Facility.

A. Source protection – Systems should inspect the areas around their sources for any new sources of contamination.

B. Disinfection Treatment (if applicable) – Systems should perform routine maintenance on all disinfection treatment equipment.

C. Other Treatment (if applicable) – Systems should perform routine maintenance on all wastewater treatment equipment.

D. Storage (if applicable) – Systems should inspect lagoon liners for any possible holes for repair if needed.

E. Monthly Sampling – Systems are required to collect wastewater samples and verify with the laboratory that there are no contaminants present. A monthly sample must be collected at evenly spaced time intervals, from May through October.

Seasonal Startup and Shutdown Procedures

B. Fall Shutdown

Bradford Pump Station

This system is in operation year-round. The pumps require no lubrication under normal operating conditions. Conduct a daily visual inspection of the system while the pumps are in operation to determine if they are operating as designed. This can be accomplished by manually operating the mercury switches, if necessary.

Receiving Pit

1. Make sure that the receiving pit and manual bar screen are clean and free of all debris.

Comminutor Pit

1. Cover the control panel with plastic.

2. Check inside manhole to make sure the drain line is open.

Aeration Lagoon and Holding Pond

Aeration Lagoon:

1. Three days after the last load of sewage has been dumped into the lagoon, two of the aerators can be removed for the winter. Shut the circuit breaker OFF on the two aerators that are being removed.

2. The lagoon volume required for the sewage from the Bradford Ranger Station and winter precipitation necessitates lowering the lagoon three feet below normal operating level. This will be a manual operation. Lower water level to the 25th bolt on the loading dock

During the shut-down period, it will be necessary to spray 14,400 gallons three times per week for six weeks. The upper two feet of drawdown can be achieved by opening the upper draw down valve, which will drain through the chlorinator. Once the holding pond reaches normal operating level, shut the valve, and set the time clock to operate for twenty hours. Every other day, repeat the same procedure until the lagoon level has dropped to the elevation of the drawdown pipe. The last one foot of sewage will have to be drained out by opening the lagoon drain valve. An automatic chlorinator will have to be set up to add chlorine while draining the lagoon by this method. Again, fill the holding pond to normal operating level. Allow the sewage to set overnight in the holding pond before starting the spray irrigation. Repeat this procedure until there is only one foot of sewage over the bottom of the aerator dock.

3. The last aerator should be removed for the winter. Shut the circuit breaker OFF. Cover the aerators with plastic to protect them from the elements. It may be necessary to use a rowboat to remove the last aerator.

Holding Pond:

Beginning on or around September 1, keep Holding Pond pumped down to lowest level.

5. Remove the water meter at the well and store it at Ranger Station garage workshop.

Control Building

1. Remove tablets from chlorinator feed tubes (Sanuril - 115 chlorine tablets) and store in an airtight container.

Sampling, Testing and Monitoring

Sampling and testing of the treated effluent must be completed on a regularly scheduled basis and as required by the facilities NPDES discharge permit. The operator is responsible for collecting effluent samples and delivering them to the Contract Laboratory. Samples shall be collected two times per month from May through November.

Effluent samples shall be collected from the sampling port located just past the flow meter on the effluent pipe from the spray irrigation pump to the spray field. Samples shall be analyzed for the parameters listed on the DMR.

There are six test wells in the spray irrigation area that should be tested for fecal coliform bacteria every other month, starting in June and ending in October. Any positive tests will be reported to the Forest Engineer. Additionally, if there is water in the treatment lagoon monitoring wells, collect a sample from the wells and have the sample tested for fecal coliform bacteria. Directions for taking these samples are included below. Samples will be taken by the operator and run by the approved contract laboratory.

All testing and sampling shall be conducted in accordance with applicable permit limitations and in compliance with all EPA and Pennsylvania Department of Environmental Protection (PA DEP) regulations. Sampling and testing shall be conducted by a Pennsylvania certified wastewater plant operator.

All test results should be mailed to the Forest Engineer and should be added to this Manual in Appendix G.

The procedure for collecting bacteriological samples consists of the following:

1. Obtain sample bottles and forms from the approved laboratory.

2. Wash hands and wear latex gloves if possible.

3. Take samples from all approved sampling locations.

4. Avoid contamination of the sample during collection. Keep the sample bottle closed until the sample is collected. Do not touch the threads on the cap or the neck of the sample bottle and do not place the cap on the ground. Do not rinse the sample bottle before collecting the sample, as sometimes chemicals are added to neutralize residual chlorine in the sample.

5. Hold the sample bottle near the bottom, fill it ¾ full, and replace the cap immediately.

6. Label the sample bottle, fill out the collection form, and deliver the form and sample to the laboratory. Keep a copy of the form for your records.

7. Samples should be kept upright and refrigerated or kept on ice. Deliver the samples to the laboratory within 4 hours of being collected and before the contract laboratory closes for the day. Coordinate sample times with the contract laboratory. It is best to collect bacteria samples first thing in the morning and deliver them to the laboratory by noon so that all holding times are maintained. The holding time for fecal Coliform bacteria is 6 hours.

Recordkeeping and Reporting

It is important to keep records of all condition surveys, water quality testing, DMRs, data logs, routine maintenance, and equipment repairs/replacements. Ensure that updated manufacturer’s literature is added to this manual when components are added or replaced. Copies of all reports and tests should be added to this manual. Copies of state required parameter testing shall be kept for a minimum of 5 years.

Wastewater System Condition Survey

A condition survey is a physical inspection of the wastewater treatment facility. The survey should be conducted annually to assess the overall condition and operation of the facility. The survey should note any recent alterations or additions to the system or the facility equipment, recommend any corrections to system operation or equipment replacement, and note any potential facility issues.

A Wastewater System Condition Survey generally includes the following:

1. Description of site features.

2. Assessment of treatment tanks.

3. Assessment of treatment equipment.

4. Description of small equipment enclosures (not on building inventory).

5. Miscellaneous equipment and records.

6. Assessment of the collection system.

Ideally, condition surveys can be conducted semi-annually for efficient, ongoing system operation. Condition surveys conducted in the fall after shut-down can identify issues that should be corrected before start-up of the next season. Plans can be made, and parts can be ordered during the winter to prepare for early season maintenance. Condition surveys conducted in the spring before start-up can identify any damage or necessary repair from vandalism, storms, frost action, etc. All condition surveys should be added to this manual in Appendix H, including any notes, sketches, and correspondence regarding facility issues. Condition Surveys are required each Spring before start-up and are encouraged in the Fall, but not required.

Recordkeeping and Testing Results All flow and treatment records as well as wastewater testing results should be added to this manual. Laboratory testing data (Appendix H) and DMRs (Appendix I) should be added to this manual as they are received/generated.

Maintenance Log Keep an updated log of all maintenance activities performed, including the location and any problems encountered. Copies of the maintenance log should be added to this manual at the end of each operating season.

Flow Logs Flow logs showing the cumulative flow meter readings and the daily flows pumped to the spray field should be added to Appendix K at the end of each year. Insert all logs showing the total volume of wastewater received at the facility each day in Appendix K.
