Ohmsett Basin Discharge Operational Procedures

1. REQUIREMENT

Contract E17PC00014, Task Order E17PD00117, Section 2.4.1.12.E. Detailed Operations Manuals. These manuals detail required routine activities and are to be used as references by the Contractor in operating the systems described. These manuals also guide the routine operations and maintenance of the facility.

The Contractor shall update the manuals as needed when major changes occur.

Contract E17PC00014, Task Order E17PD00117, Section 2.4.3.2. Contractor shall formalize an agreement with the Township of Middletown Sewerage Authority (TOMSA) to discharge excess clean tank water, due to seasonal precipitation, to TOMSA’s water treatment system. ARA-Ohmsett finalized an agreement with TOMSA that is substantively based upon the original proposed agreement designated Version 5: March 5, 2019, and includes updated provisions as described herein.

This manual also covers operational and regulatory practices associated with discharging the main test tank water to the Sandy Hook Bay. A discharge of this nature would be required for larger volumes of accumulated stormwater in the test tank, and in the case of total tank emptying to affect periodic tank refurbishment and upgrades. Accordingly, as required by our New Jersey Pollutant Discharge Elimination System, Discharge to Surface Water (NJPDES-DSW) permit (referenced below), the New Jersey Department of Environmental Protection (NJDEP) was provided with a digital copy of this revised document. This document was submitted to the NJDEP Division of Water Quality, Central Enforcement Office by May 7, 2020, as required. In the future, changes of substance to this document will also require submittal of the updated document to the NJDEP.

Any significant discharge of the Ohmsett test tank water to the environment or non-Ohmsett systems such as TOMSA, will be proceeded by notification to the appropriate authorities, namely, the NJDEP (see NJPDES permit reference below), TOMSA, and Naval Weapons Station (NWS) Earle Base Environmental.

2. APPROACH

2.1. GENERAL

Periodically, the Ohmsett Facility must remove water from the test basin (tank) for two different reasons.

The first involves complete draining of the tank to affect inspections, maintenance, repairs, upgrades, and modifications. A discharge of this nature occurs on a scheduled basis, usually once every five years. The second involves incremental removal of excess water, usually due to precipitation, to maintain a proper water level for operations, testing, and training. Further description of these operations is as follows.

2.1.1. Tank Emptying for Maintenance

Total emptying of the tank for maintenance and major upgrades is usually done on a five-year rotation.

The tank is emptied to the Sandy Hook Bay as permitted and regulated by a NJPDES-DSW Permit #NJ0005762, issued March 31, 2022, effective July 1, 2022, and expiring June 30, 2027. Discharge to the Sandy Hook Bay is accomplished through a controlled process system that includes a staged array of fixed and portable pumps, fixed and portable piping and hoses, and the permanent diatomaceous earth (DE) and cellulose filtration system. In addition to these Ohmsett-based systems, compliance with regulated effluent standards may require a temporary system for polishing treatment of water prior to discharge.

Polishing treatment may include, but is not limited to, further filtration of particulate, ion exchange resin treatment for metals, and/or granular activated carbon (GAC) adsorption treatment for residual organic contaminants. Discharge through any treatment would proceed at a flow rate limited by the residence time of any applied treatment. Usually, this flow rate proceeds at approximately 300 gallons per minute (gpm). Verification of compliance with regulated (NJPDES-DSW) water quality limits will be through third-party, New Jersey-certified laboratories. Effluent limits and monitoring requirements are provided in Part III, Limits and Monitoring Requirements of the referenced NJPDES-DSW Permit. A table of the specific analytical requirements is provided in Appendix A of this document which shows the Part III requirements of the NJPDES-DSW Permit.

Ultimate discharge of water to the bay will be at a point on the old trestle section of the NWS Earle pier approximately 1000 feet to 1500 feet from mean low tide line, and at the approximate coordinates of 40d 26’ 20.1” N Latitude, 74d 03’ 37.3” W Longitude. This temporary discharge point, when actively established, is known as DSN-001A.

2.1.2. Discharge to TOMSA (sanitary sewer) to Adjust for Storm Water

Ohmsett historically discharged to TOMSA when seasonal precipitation caused the tank water level to rise above the operational limits for testing or training activities. This discharge would be initiated as precipitation would dictate. More recently, routine discharge of Ohmsett tank water to the sanitary sewer has come under closer review and scrutiny by TOMSA. In response, ARA developed a new procedure, the Standard Operating Procedure (SOP): Periodic Water Level Control Discharge of the Ohmsett Test Tank to the Sanitary Sewer, dated March 7, 2019, provided in Appendix B of this document. Consequently, the TOMSA discharge has been limited to 20 gpm, as required by TOMSA, and will take place through a supplemental granular activated carbon (GAC) adsorption system. To this end, a new more robust and corrosion resistant system for this discharge has been constructed. It will provide a more reliable and more operationally workable GAC polished water discharge at a rate of 20 gpm to TOMSA unless special authorization is received. The discharge SOP and agreement with TOMSA have been updated appropriately. It is anticipated that this new system, and the proposed flowrate, should be acceptable to TOMSA. A conceptual representation of this proposed discharge system is included in Appendix C.

2.1.3. Discharge to the Sandy Hook Bay to Adjust for Storm Water

Discharge of excess tank water to the sanitary sewer is accompanied by the risk that TOMSA could, at any time, either limit discharge flowrate or ask for cessation of discharge entirely. This could be due to any number of operational factors at TOMSA, all of which would be out of ARA-Ohmsett’s control. Since this outside variable could severely impact operations at Ohmsett, an alternate mode of excess storm water discharge needs to be held in option. That option is to transfer excess water from the test tank to on-site holding storage, which would usually consist of two to four transportable frac tanks held in reserve. Once a workable volume of water is collected, discharge of the test tank water to the Sandy Hook Bay would proceed as in Section 2.1.1 above. Concurrently, the water stored in the frac tanks would be transferred back to the test tank until the frac tanks are empty. Discharge would then continue until the optimal test tank level is attained. In this way, water stored in the frac tanks would not be discharged directly to the bay, but it would be discharged through full treatment with the rest of the tank water. Reporting and effluent quality testing would proceed as per the NJPDES-DSW (Section 2.8).

2.1.4. Operator and Staff Responsibilities

Any person involved with operations, monitoring, or oversight of Ohmsett test basin water discharge to the Sandy Hook Bay or to TOMSA, as described in this section, must be thoroughly familiar with the descriptions, instructions, and provisions of this section. More specifically, any operator, supervisor, or manager who is directly involved in this discharge operation must be knowledgeable of, and compliant with the following.

3. OPERATING PROCEDURES

3.1. GENERAL

Discharge of the Ohmsett test tank water is accomplished by diverting effluent flow from the DE filtration system through a secondary, temporary filtering and GAC adsorption system (secondary treatment) as appropriate. Other secondary treatment provisions may include ion exchange resin, or specific filtration as needed. Effluent from the secondary treatment system is then transferred through a series of hoses overland to a point on the old trestle portion of the NWS Earle pier approximately 1000 to 1500 feet into the Sandy Hook Bay.

3.2. PRE-DISCHARGE OPERATIONS

In the days prior to discharge, the test tank water should be recirculated through the DE filter system to meet the effluent limits stated in the NJPDES-DSW permit. The appropriate filtration and/or adsorption media should be employed in accordance with the Ohmsett Filtration Manual. Filtration operating parameters such as pressure and pressure differentials, flow rates, type and mass of media used, and cycle times will be recorded as a function of time. Intermediate operational analyses should be performed to indicate treatment progress using the Ohmsett on-site laboratory. This will provide reliable data on a timely basis to be used in guiding the operation of the filtration system. Additionally, physical and chemical analysis may be performed at an independent New Jersey-certified laboratory to appropriately document the quality of the test tank water prior to discharge. The Central Bureau of Water Compliance and Enforcement should be notified two weeks prior to the anticipated discharge.

3.3. PLACEMENT OF DISCHARGE HOSE

The discharge hose used to transfer test tank water to the Sandy Hook Bay is typically six-inch, lay-flat hose equipped with cam and groove couplings. Refer to the Operating Manual for Liquid Transfer for the U.S. Department of the Interior, Bureau of Safety and Environmental Enforcement, Ohmsett Facility, dated September 30, 2020, for general procedures in the use and handling of this type of hose. All transfer hoses used for this discharge should be clean and free of oil or debris.

For this application, the discharge hose will be routed from the six-inch standpipe located on the northwest side of the test basin to the influent side of the secondary filtration system (typically GAC adsorption) if such a system is used (see Section 3.5). The hose will then be routed over the ground to the base of the NWS Earle pier complex. Once on the pier, the hose will be routed out onto the “Old Trestle” (wooden portion) of the pier to a point approximately 1000 to 1500 feet offshore. The approximate coordinates are 40o 26.1’ 20” N Latitude, 74o 3’ 37.3” W Longitude. This position should be far enough offshore to account for tidal changes and ensure that discharge water is always contacting receiving waters. Care must be taken to minimize exposure of the hose to vehicular traffic and to minimize disruption to routine activities in the area. When not in use, the hose should be left uncoupled and coiled off roadways. When in use, traffic cones should be employed to route vehicular traffic around hoses.

When handling open hose, care should be exercised so as not to introduce debris from the surrounding ground.

At the discharge point (DSN001A) on the Old Trestle, the six-inch hose run will be terminated by a specially designed collar that is fitted with a 1/2-inch sample port. The sleeve will be clamped to a bracket that is, in turn, fixed to the wooden gunwales of the pier. This configuration allows for the safe placement of the terminus point, easy visual monitoring of effluent flow to the bay, and a readily accessible sample point.

3.4. DISCHARGE PUMPING

Discharge of the test tank water to the Sandy Hook Bay takes place through P-1, the main pump of the DE filtration system. An inline flowmeter is employed at the most effluent point in the system prior to the discharge hose to the pier. Pumping through this system is initiated through the following general steps.

1. The DE filtration system is started and run in the On-Stream Operational Mode. In this mode, test basin water is circulated by P-1 through the DE filter and back to the head (south end) of the test tank.

2. When all systems are ready, the 12-inch valve that diverts flow through the transition fitting and into the temporary six-inch hose discharge system is slowly opened. At the same time, the 12-inch valve that regulates flow back to the head of the test basin at the south end of the tank is slowly closed to increase head to the north end discharge.

3. The process of opening the valve to the hose discharge system and closing the valve at the head of the test tank is continued in a coordinated fashion (radio communication is necessary) until the appropriate flow is established through secondary treatment if employed, and to the discharge hose to the pier.

4. The radio-coordinated process of balancing these flows continues until the operational discharge pressure at P-1 is within the range of 25 to 30 psi. Typical flow rate ranges from 200 to 300 gallons per minute with secondary treatment connected (see below).

P-1, the DE filtration system, should be continually manned and the operating parameters monitored in accordance with the above procedure. Initial and periodic soundings, along with start and measurement times, should be made in the main test basin to monitor the overall discharge rate.

Inspection of the entire discharge hose run should be manually inspected at least twice a shift. The discharge integrity at DSN001A should also be manually inspected twice a shift.

3.5. SECONDARY TREATMENT SYSTEM

If filtration alone cannot provide test basin water quality that meets effluent standards as provided in the permit regulated Discharge and Monitoring Requirements (Table 1), a secondary mode of treatment would be required. Depending upon the regulated analytes present in the effluent, their respective concentrations, and the regulated discharge requirements, secondary modes of treatment could include specialized filtration, adsorption media such as GAC, ion exchange resin contactors, flocculation/precipitation, or others. During previous discharges to the Sandy Hook Bay, it had been necessary to use ion exchange contactors with GAC polishing to remove zinc from the water prior to discharge. A more recent discharge event required the use of full treatment GAC adsorbers to lower the concentration of chlorine-produced oxidants. Flow rates for these systems typically range from 200 to 300 gpm.

It is important to note that if secondary treatment is required, and whatever mode of treatment is chosen, it will be applied as a self-contained modular system in-line after the Ohmsett filtration operation.

Modular systems of this type are readily available as self-contained systems that can be leased through reputable firms competitively. In addition to the equipment, most firms offer ancillary services such as consultation, analytical services, and disposal services associated with the operation of these modular systems. Effluent from any secondary treatment system would be discharged through the discharge hose to the Navy trestle as described in this Section 3.3.

3.6. EFFLUENT SAMPLING

At least one round of effluent water samples will be collected and analyzed in accordance the facility NJPDES/DSW Permit. All effluent water samples will be taken at the sample port located on the discharge collar just prior to discharge to the Sandy Hook Bay surface water. As previously stated, this point is known as DSN001A. The gathering, handling, transport, documentation, and analysis of all effluent samples will be performed by a third part laboratory certified in New Jersey for the analyses being performed. All monitoring will be conducted in accordance with the NJDEP Field Sampling Procedures Manual. Results will be reported in the next quarterly Discharge Monitoring Report (DMR).

3.7. DISCHARGE TERMINATION

In the case of complete test tank emptying for maintenance (typical five-year cycle), discharge should continue at a controlled flow rate until a vortex appears at the surface of the test basin water in the vicinity of the filtration system inlet. This phenomenon will take place when the water level in the test basin is approximately 8 to 12 inches in height. At that point in time, the flow rate should be reduced while maintaining pump P-1 discharge pressure at 22 psi. Discharge can continue at this lower rate until backpressure and prime start to diminish to P-1. This occurs when the level of water left in the test basin is approximately two or three inches. At this point, the pump rate at P-1 should be throttled back until the pump can be shut down.

The remaining two to three inches of water may then be removed using a suitable immersible pump, either air driven or hydraulically driven, in the filter inlet sump at the north end of the tank. This represents a low, or drainage point in the tank which will assist in final water removal. Water pumped in this way will be directed through the 10,000-pound GAC adsorbers prior to final discharge to the bay. Flow rate to the GAC should be limited to 50 to 150 gpm as operationally appropriate. During this actively monitored phase of the operation any residual oil, grease, or solid residue will be prevented from entering the pump. This may be done using sorbent materials (pads and boom), physical raking, or selective pumping with a smaller pump. Residual fluids and solids removed in this manner will be held for disposal through a qualified licensed disposal organization

In the case of incremental test tank emptying to achieve an operational water level, discharge would continue to the predetermined level in the tank. At that point, the discharge would be terminated.

After any discharge event all hoses should be uncoupled, drained in a controlled fashion, and carefully rolled and stored. The Central Bureau of Water Compliance and Enforcement should be notified upon completion of the discharge event.

3 INSPECTION AND MAINTENANCE

4.1 PRIOR TO DISCHARGE

The DE filtration system should be run on normal on-stream filtration mode and should be monitored for proper operation. Additionally, the system should be checked for leaks at all fittings, valves, joints, seams, flanges, or any other part of the system where leaks may occur. The discharge transition fitting should be checked for integrity and proper fit. The six-inch hoses should be clean and in good condition. All couplings should be rechecked for proper condition and fit.

The hose route should be checked to be sure that hose lengths and fittings are not in danger of being damaged, that the route does not interfere with safe operations in the area, and that placement and securing of hoses and fittings minimizes uncontrolled movement due to hydraulic impulse and momentum. The appropriate analyses must be performed on the test basin water to ensure compliance with discharge effluent quality and limits.

4.2 PREPARING THE SECONDARY FILTRATION SYSTEM FOR OPERATION

Twelve to 24 hours prior to discharging basin water, the secondary treatment system vessels (if used) are to be filled with test tank basin water. Prior to use, establish flow through the vessels returning flow to the test basin to ensure conditioning and flushing of system media.

During the first 30 minutes of discharge, the entire discharge system, as listed above, should be inspected and monitored for leaks or malfunction. Also, during discharge, the entire system from the DE filtration system to the discharge point at DSN001A should be inspected on a walking tour every 60 minutes.

5 EMERGENCY PLAN

5.1 GENERAL

In general, response procedures associated with emergency situations that may occur during discharge should focus on the following:

• Elimination of immediate threat to human health and safety

• Elimination of immediate threat to the environment

• Assurance of effluent quality (this may necessitate the interruption or termination of the discharge event)

• Notification of the appropriate emergency response forces if necessary

• Notification of the appropriate regulatory and management personnel

Discharge of the Ohmsett test basin water is not part of the public infrastructure; nor do other critical processes, either private or public, rely upon it. Therefore, prudence would dictate that the most conservative course of action in an emergency would be to cease discharging.

5.2 VULNERABILITY ANALYSIS

5.2.1 Power Supply

Power to the Ohmsett facility is supplied by Jersey Central Power and Light (JCP&L), the local power utility, and is beyond the control of Ohmsett. A decrease or interruption in power would directly affect electrically driven equipment at the site. Ohmsett maintains several portable battery-powered light sources and a gasoline engine powered, 6 KVA, 120/240 VAC, single phase generator. This equipment would provide light to aid personnel in response operations.

P-1, the main pump used in the DE filtration system, is electrically driven and would stop operating in the event of a power failure. However, this would not serve as a threat to human safety or the environment since discharge to the Sandy Hook Bay would cease.

5.2.2 Communication

Discharge of the test basin water to the bay is a self-contained, fully manned operation. Therefore, short of regional or national emergency, an interruption in communication outside of the facility would not adversely affect the discharge operation. Internal communication is either by direct verbal contact, using battery powered two-way radios, or via cell phones.

5.2.3 Equipment

Most of the major equipment at Ohmsett is powered electrically. The effect of power failure upon discharge operations has been described above.

Other areas of equipment failure that could affect the discharge operation are leaks or uncontrolled discharge of effluent water due to failure in seals, gaskets, packing, fittings, or hoses. These types of failures are minimized by a rigorous routine maintenance program carried out by facility personnel, and comprehensive inspection of the discharge system prior to startup and during operation. Failure that does occur would be discovered immediately since the entire operation is fully manned during active discharge operations. Furthermore, the system used for discharge is completely contained on a single site. Failure that involves shutdown would result in a cessation of discharge to the Sandy Hook Bay.

5.2.4 Supplies

Since the described discharge is a single, self-contained, discrete event with a well-defined duration in time, all supplies necessary for continuance of a successful operation are stocked on site prior to startup.

Therefore, the vulnerability of the operation to an interruption of supplies is very low.

5.2.5 Personnel

During discharge operations, a group of four to six Ohmsett personnel, constantly man the discharge system during all active discharge operations. Given the number of personnel available, their level of training and experience, and the availability of this manual and other established procedures; the level of vulnerability to the discharge operation is minimized.

5.2.6 Security

The Ohmsett facility resides on a U.S. Naval Base. All discharge operations take place within the physical confines of that base. The base is fully secured and patrolled 24-hours per day. Additionally, as stated earlier, the discharge event is fully manned on a full-time basis. Therefore, the level of vulnerability due to security breech is minimized.

5.3 EMERGENCY OPERATIONS PLAN

All personnel involved with all operations associated with discharge of the Ohmsett test basin to the Sandy Hook Bay will familiarize themselves with the following emergency contacts:

NWS Earle Fire Department (fire, emergency, spills, injury)

First Aid Squad

Riverview Medical Center (hospital) ................................................... 98-732-741-2700

Poison Control Center ..................................................................... 98-1-800-962-1253

Security

Waterfront Security Guard .......................................................................Ext. 7011

Waterfront Complex Front Gate ...............................................................Ext. 7322

Security (general) .....................................................................................Ext. 7104

5.3.1 Power Failure

In the event of an interruption of, or reduction to, power, P-1 will cease operation and discharge from the test basin will stop. Additionally, all switching to P-1 should be opened, and all valves should be positioned in the On-Stream Operational Mode. If necessary, battery powered lights should be used for visibility, and the six KVA generator should be deployed.

5.3.2 Communication Failure

Verbal communication should be established with security via battery powered two-way radios, cell phones, and/or through use of a messenger is necessary. The status of general communication to the facility should be monitored.

5.3.3 Equipment Failure

In the event of failure of P-1, the response procedure should be the same as a power failure. P-1 and the filtration system should be switched to the On-Stream Operation Mode.

Any leaks or discharge of effluent water should be addressed by diverting flow away from the area or system in question, then troubleshooting and repairing the leak before flow is re-established. This may require switching to the On-Stream Operation Mode, as stated above, or shutting down all pumping operations.

Spill of regulated or hazardous substances, such a petroleum liquid, should be responded to by immediately stopping the discharge or leak if this can be done quickly and safely. Then, according to the NWS Earle DPCC Plan, operational personnel must leave the area and immediately notify the fire department via the 24-hour base fire and emergency phone number, ext. 7133. Operational personnel should then remain available to assist fire, spill, and emergency forces as requested.

5.3.4 Interruption of Critical Supplies

This should not be an issue in this operation. However, in the rare event that an interruption in critical supplies could affect the safety of the discharge operation, or the environmental quality of the effluent, the entire operation should be interrupted until the matter can be rectified. This could involve diverting effluent flow by switching to the On-Stream Operation Mode as described earlier.

5.3.5 Security Breech

Any problem with security, such as intrusion by unauthorized personnel, should be referred immediately and directly to 911.

Ohmsett Facility DOI-Bureau of Safety and Environmental Enforcement (BSEE) Applied Research Associates (ARA), contracting operator

Standard Operating Procedure:

Periodic Water Level Control Discharge of the Ohmsett Test Tank to the Sanitary Sewer

1. Background

Routine and effective operations in the Ohmsett Facility test tank require that the tank water level be maintained at 8 feet ± 5%. An inch of rain (or equivalent precipitation) in the open tank equates to approximately 1.3 inches of rise in the water level. This increase is due to the large amount of work space and containment that drains to the tank. Evaporation rates from the tank surface are not sufficient to offset this rain accumulation. Therefore, significant periods of precipitation most often result in an unacceptable height to the tank water level regardless of the season. To counter this net gain in water level and allow the Ohmsett Facility to continue to operate, it periodically becomes necessary to discharge water from the tank. It is therefore proposed that the Ohmsett Facility be permitted to discharge excess water to the Township of Middletown Sewerage Authority (TOMSA) on a contingency basis as a function of significant precipitation events. Such a discharge would be fully monitored and documented, and would proceed only upon prior notice to and permission from TOMSA. The following is the standard operating procedure.

Each entity shall provide written notice to the other regarding changes to the contact list. Such notice shall be provided within a timeframe that maintains the transfer of information required under this SOP.

All documentation and notifications, including intent to discharge, shall be transmitted via the most recent e-mail addresses provided by TOMSA and Ohmsett. All discharge notifications shall include the planned start time of discharge, the overall intended time period of discharge and an estimate of the volume of discharge. Notice of discharge from the Ohmsett tank shall be provided to TOMSA by Ohmsett at least one business day prior its start. Other relevant parameters such as pre-discharge water analyses (see below) will also be reported. TOMSA will also be notified when a discharge event is complete and will be provided a final volume of water discharged over the event period.

3. Source and Discharge Location Part of maintaining water quality in the Ohmsett test tank includes routine filtering through a diatomaceous earth (DE) and supplemental media filter system in a closed loop to and from the tank. Tank water enters the filtering system through a twelve-inch inlet in a sump at the north east corner of the test tank. Filtration takes place at a volume flow rate range of 1,500 to 2,000 gpm. The effluent from this operation will be the source of filtered water for discharge to TOMSA during tank level lowering events. The final reduced flow and metered discharge (see below) will be directed to the sanitary sewer manhole and pump station located in the ground just north and west of the test tank. The pump discharges to TOMSA MH#5-103, the northern most manhole on Cedar Avenue in Leonardo.

4. Discharge Specification

Discharge to the sanitary sewer will be conducted through a pipe tapped from the discharge flow of the Ohmsett tank water filtration system. Ohmsett will strictly adhere to discharge flow limits of no more than 20 gpm instantaneous flow rate, and a total cumulative daily discharge volume of no more than 25,000 gallons.

A discharge event will take place only after analyzed water quality is within the limits set forth in TOMSA’s Rules and Regulations.

Discharge will be conducted through a totalizing flow meter with digital data recording capability.

In addition to monitoring discharge flow rate and flow totalizing via a meter, total discharge from the tank will be confirmed by physical sounding of the Ohmsett test tank before and after a discharge event. It is of note that an inch of water in the tank equates to approximately 27,000 gallons of water.

TOMSA reserves the right to suspend acceptance of discharge from the Ohmsett tank if it believes that the discharge has had or will have a negative impact on its conveyance and/or treatment facilities.

5. Analysis and Documentation

Prior to notification of the intent to discharge to TOMSA, the following analyses will be conducted at the Ohmsett Facility to assure water quality:

• Tank water will be visually inspected prior to discharge. The surface water over the tank water inlet to the filter system will be actively cleared using high pressure water fan(s) and surface oil that may be present will be skimmed and removed.

• A tank water grab sample of appropriate volume will be taken from a sampling point just down-stream of the filter and prior to the discharge point to TOMSA.

The grab sample will be tested in the Ohmsett laboratory for total petroleum hydrocarbon (TPHC) by non-dispersive infrared spectrometer (NDIR) and chemical oxygen demand (COD) by thermal/catalytic digestion.

• The grab sample will also be analyzed in the Ohmsett laboratory for turbidity, salinity, density, and pH.

• In the event of dispersant testing prior to the intent to discharge, the Ohmsett laboratory will conduct interfacial tension (IFT) analyses* on samples of tank water prior to dispersant testing and after dispersant removal from the tank water.

Tank water analytical data produced by the Ohmsett laboratory will be reported to TOMSA as part of the notification to discharge as provided above. If a discharge period extends beyond 72 hours, an additional set of Ohmsett laboratory analyses will be conducted and reported for each additional 72 hour period.

Additionally, once a quarter, a tank water grab sample will be analyzed through an outside certified laboratory for pH, salinity, oil and grease, COD, and metals (Al, As, Cr, Cd, Fe, Hg, Ni, Mo, Ag, Se, Pb, and Zn). This quarterly test also will satisfy a BSEE contractual requirement for quarterly tank water analysis. This quarterly data will be made available to TOMSA.

Ohmsett will submit a monthly report to TOMSA for billing and historical purpose. This monthly report will include discrete discharge period water volumes with accompanying Ohmsett laboratory analytical report, the start and end time and date for each discharge, total volume discharged each calendar day, cumulative monthly water discharge volume, and quarterly certified analytical data as appropriate.

Documentation of these Ohmsett laboratory data, as well as documentation from the certified quarterly laboratory reports will be archived at Ohmsett for a period of five years. The date and time of discharge, flow rate, water temperature, and cumulative discharge for 24 hour periods will also be documented and archived for five years.

Compliance with all applicable regulations and with any imposed reporting requirements will be strictly observed.

*IFT between tank water and USP Grade mineral oil is used as a reliable surrogate test for the presence of the surfactant systems used in dispersant. Pre-dispersant testing of IFT is compared to post dispersant testing of IFT in tracking the removal of surfactants from the test tank water.

6. Billing

TOMSA will bill Ohmsett for the discharge from the test tank and domestic sanitary sewer waste from its administration buildings. Neither discharge is metered as part of the Navy’s discharge to TOMSA. Ohmsett will be billed as follows:

1. Domestic use will be billed at a fixed rate of 5 units per quarter where a unit is based on the square footage of the office space

2. Basic service fee applied to the tank discharge account includes up to 15,000-gal discharge per quarter. Total tank discharge in excess of the 15,000 gal/ quarter will be billed at a rate per 1,000 gallons.

The rate billed will be the prevailing rate at the time of discharge as set by TOMSA’s Board. The current rates per quarter are domestic sewer $80/ unit, basic service fee for tank discharge is $80 with $5.33/ 1000 over the 15,000 thresholds.

Bills will be sent to the address provided on the application for sewer service completed by Ohmsett unless TOMSA is notified in writing otherwise.

APPENDIX C. DISCHARGE SYSTEM TO TOMSA

System for Discharge of Excess Storm Water to TOMSA

April 21, 2020

Design Objectives

• Discharge flowrate of 20 gpm to the sanitary sewer of TOMSA

• Pre-discharge water treatment using diatomaceous earth (DE) filtration followed by liquid phase

GAC adsorption

• Minimum impact to other operations of the facility

• Modular approach to maximize ability to nominally increase flow capacity, and provide the flexibility to adapt to a more permanent operational configuration in the future

• Ability to discharge on a 24-hour basis

Operational and Process Limitations

• Access and geometric limitations for reliable flow from the effluent of the existing Ohmsett DE filter, and limited space in the filtration building

• DE filter effluent high flow (1500 – 2000 gpm), but low energy (4 to 10 psi, varies with filter DP)

• Need for adequate capacity of GAC unit(s) for pressure, flow rate, and resistance to corrosive saltwater effluent

• Limited interior space with controlled environment (weather and temperature) that is proximal with the discharge point manhole

• Manhole wastewater sump pump that is not corrosion resistant

• Provision to routinely interrupt process to meet operational requirements of the facility, and varying load associated with rain events

Design Parameters and Response

• Filter effluent take-off at the 6-inch standpipe located at the northwest corner of the test tank.

This location provides ready access, ease of installation or modification, proximity to the ultimate discharge point to the sanitary sewer, and an adequate flow regime. Additionally, the standpipe and flange provide ready support for a small platform to hold a pump, meter, and piping.

• Use of a corrosion resistant pump to convert a flooded, high volume, low pressure flow to a low volume (10 gpm) higher pressure (15–25 psi) feed for a downstream, in-line GAC vessel system prior to discharge.

• Piping of flow from the standpipe, using an existing overhead utility race, to the north side of Building R26.

• Use of an existing former oil-water separator building located at the north side of R26 as a climate controlled enclosure for the GAC vessels and ancillary piping and equipment. This building is also adjacent to the discharge manway.

• Use of stainless steel, 55-gallon, 150 # GAC, converted open-head drums as GAC vessels. These vessels are corrosion resistant, and pressure rated to allow for a 5 gpm/vessel throughput per vessel. Due to their compact size, they also provide for modular incorporation into a system and flexibility in series and/or parallel piping. They are also open-head vessels that will allow for GAC change-out as necessary.

• Replacement of the manhole wastewater sump pump with a corrosion resistant model.

• System provisions for drainage, and freshwater flushing.

Figures F0016-20-03A, -03B, and 03C provide conceptual sketches of the planned system (Attachment A).

In general, the existing 6-inch standpipe flange will be used to support an integrated pipe and bracket system that will support a ½ HP centrifugal corrosion resistant pump, a flow meter, a PVC globe valve for throttling, and associated piping and fittings. This system will be removable, self-supporting, and will provide ample flooded flow to the suction of the pump. This system will be connected to a downstream pipe race terminating at the GAC adsorbers that will be in the former R26 oil-water separator enclosure.

The calculated overall head of the system (Hazen-Williams and Crane, tech. paper 410) beyond the pump is approximately 35 feet. The chosen pump will provide added energy to maintain a flowrate of 10 gpm through a flow meter, metering valve, pipe system, and two or four GAC adsorbers units, with ultimate discharge to the sanitary man hole north of Building R26.

The four GAC units are each 55-gallon, modified stainless steel drums packed with 150 # of media. Each drum can support 5 gpm at the calculated system pressure range of 15 to 25 psig. In this way, the drums may be set up in parallel or in series as required. To achieve 20 gpm, at least two drums in parallel will be needed. Higher flow rates may be achieved by placing more drums in parallel. Each drum represents a 2 to 3 psi drop (per Darcy’s relation) per drum and carbon bed.
