WIDETT CIRCLE TERMINAL WASTEWATER TREATMENT AND REUSE FACILITY OPERATIONS AND MAINTENANCE

Description of Services

These specifications define the conditions and requirements for the operation and maintenance (O&M) of the existing wastewater Treatment and Reuse facility (Facility) located at the Widett Circle. Environmental Subcontractor shall furnish labor, parts, and equipment necessary to operate, service, maintain, and repair the Facility, appurtenances and associated equipment. The Facility unit operations and primary system components are listed in Table ES6-1 where available.

From the MWRA meter, water is manually added to the system at Tank # 109, the clean rinse tank. The water progresses through the several stages of the train wash, gray rinse detergent brushes, detergent arches and into the detergent recovery tank also known as Tank # 102. This tank serves both the train wash and closed loop systems. Water may be reused in the wash process or introduced into the closed loop flow.

If the water is entering the closed loop process it is transported from this same Tank # 102 through filters F101B and F102B, into Tank # 103 (where its Ph is adjusted up by the addition of Caustic Soda to a base level required by the ultra filter for process purposes) through Tank # 104, then transported to Tank #105. From Tank #105 the water may flow to any one of three separate destinations, which include the following:

The Overflow to Tank # 101

The Ultra Filter

The evaporator

When more water is pumped into Tank #105 than can be accommodated, the overflow flows through a system of pipes through the foundation of the building into OW 101 located approximately 700 feet away at column 20.

Water is continually drawn off Tank #105 and fed through the Ultra Filter. Having passed through the Ultra Filter the water is either returned to Tank # 105 as “concentrate” or transported as “permeate” to Tank # 106.

Water heavy with contaminants is drawn off near the bottom of Tank # 105 and transported to the evaporators. At the evaporators, waste products from the train wash process are concentrated and the water is vaporized and boiled off into the atmosphere.

Water from Tank # 102 (also called detergent recovery tank in its train washing capacity) may, if it does not follow the route described in section 7.1.1 of this Schedule 3.8 (Environmental Services) above, reenter the train wash process. In the train wash process water from the train wash remaining on the trains, drains onto the floor as the train moves through the building. This water is collected through a system of drains and is transported to OW 101 previously mentioned above in Section 7.1.2.1 of this Schedule 3.8 (Environmental Services). From OW 101, water is transported through Tank #101, through filters F-101A and F-102A. The water is pumped past the coalescer units (currently by-passed) and on to the same Ph adjustment area mentioned in section 7.1.1 of this Schedule 3.8 (Environmental Services) and continues on as previously described.

From Tank # 106, the water is transported to a second Ph adjustment area where Sulfuric Acid is mixed in to lower the base mixture required for Ultra Filtration. The water then passes through carbon beds (currently by-passed), resin beds (currently by-passed) and finally into the clean rinse Tank # 109 where it is mixed with water from the MWRA (if the level of water in the system is low) and is ready for re-use in the train wash process.

Summary of Work

Facility operation and maintenance shall include operating, monitoring, testing, and maintaining unit operations, appurtenances, and associated equipment including pumps, oil/water separators, filtration systems, equalization and process tanks, ultrafiltration unit, carbon adsorption units, chemical feed systems, piping, valves, storage tanks, and electrical controls and instrumentation. Environmental Subcontractor shall record data and maintain logs of monitoring, testing, and operation and maintenance activities performed under these specifications. Environmental Subcontractor shall conduct sampling and laboratory analysis required for normal operations and maintenance. Environmental Subcontractor is responsible for proper and legal handling and offsite disposal of wastes generated during Facility operation and maintenance. Environmental Subcontractor shall handle, transport, and dispose of wastes in accordance with EPA and MassDEP rules and regulations and provide testing, manifesting, and reporting services specified in Section 2 (Stormwater Inspections and Catch Basin Cleaning) of this Schedule 3.8 (Environmental Services).

The Operator acknowledges and agrees that the Operator shall be responsible for the maintenance, repair and operation of the Widett Circle wastewater treatment and reuse facility systems, as in effect on the Agreement Services Commencement Date, in accordance with the provisions of Section 4 (Onsite Subsurface Disposal System Servicing) of this Schedule 3.8 (Environmental Services) and the costs of all such services are included in the Annual Fee.
