1. The contractor shall provide procurement, handling and management functions associated with the objectives set forth in the following sections. The service provided will be in two phases: Phase I - Removal of old coolant, cleaning machine internals associated with the coolant, and recharging the machine with virgin coolant; and Phase II – Continual maintenance of the machine coolant as outlined.

2. Additionally, the contractor shall:

a) Utilize coolant manufactured by Houghton International, specifically HOCUT 795. Extensive studies and on-site testing of coolants have been conducted by Norfolk Naval Shipyard (NNSY) Industrial Engineers. HOCUT 795 is a water-soluble coolant that possesses superior coolant superior coolant qualities, as well as an ability to inhibit the growth of bacteria and fungi. Exclusive utilization of this product will enable the shipyard to consolidate the current use of various coolants and products.

b) Provide knowledgeable and experienced coolant management personnel to fulfill the contract objectives and duties, including machine-operating skills necessary to drain, circulate and recharge coolant reservoirs.

c) NNSY Shop 31 shall monitor the need for waste containers. The Government will provide bulk containers as well non-bulk Performance Oriented Packaging (POP) as approved by the Government for collection, storage, and disposal of non-bulk hazardous waste if required. Contractor shall identify personnel to be trained by Code 106 as Environmental Coordinators (ECs), primary and alternate at no expense to the contractor. The trained ECs will process non-hazardous and hazardous waste as directed by Code 106 OSHE Program Manual Chapters II-38 and II-45. Copies of these manuals are available upon request.

d) For both Phase I initial sampling and Phase II sampling, the contractor’s ECs will provide sampling request forms to Code 106 as directed by Shop 31. Sampling shall be performed in the bulk container provided by Code 106. The purpose of this sampling is to ensure the “waste stream” has not changed.

SERVICES:

I. COOLANT CLEANING (One Time requirement) A. Contractor shall provide services and resources to: machines located in the following buildings: 163, 171, 202, 234, 510 & 1505. List attached.

1. Remove used coolant from 202 pieces (+/-10%) of Industrial Plant Equipment located at the NNSY IN Portsmouth, VA as listed in Enclosure (1). The approximate quantity of liquid is 7,828 gallons (+15% variance). The contractor shall be responsible for removing waste liquid, coolant and applicable materials as they are generated. Regulated/hazardous waste must be properly packaged and labeled so that it can be turned over to NNSY Code 106 via the EC for proper disposal.

2. Utilize the cleaning procedure as outline in Enclosure (2) to remove swarf and debris from machine sumps, return trenches, oil pans, chip conveyors, filtration units. The contractor will use CIMCLEAN 30 or equivalent as the primary cleaning agent.

3. Charge machine coolant system completely with virgin coolant (5-7% HOCUT 795) manufactured by Houghton International. The contractor shall circulate the coolant thought the machine system to ensure proper operation. NNSY will provide familiarization training on the machine coolant systems.

NOTE: Removal of used coolant, cleaning and recharging of new coolant must be accomplished within eight (8) hours on each machine to prevent rust formation on critical machine components.

B. The coolant cleaning portion of this service is a one-time requirement that must be accomplished within a four (4) week period – start to finish. The contractor will coordinate with the shop representative to schedule a machine cleaning and coolant change-out. The shop reserves the right to request a change of the schedule based upon unforeseen workload requirements.

II. COOLANT MAINTENANCE

A. Provide services and resources to maintain coolant levels in 202 pieces of Industrial Plant Equipment (+-10%) previously cleaned per Section I. Any additional machine added to the coolant maintenance program would need to be cleaned to meet the criteria previously discussed. Additional machines added to the contract require sampling as described in the Scope of Work. The contractor will be responsible for proper monitoring and maintenance of machine coolant and concentration levels as specified in the proposed weekly monitoring schedule listed in Enclosure (3). Listed below is a minimum expectation of services to be provided.

1. Develop and utilize the weekly monitoring procedure as specified. This procedure will be applied to each machine on a weekly basis as a minimum.

2. Develop metrics to track coolant performance as outline in Enclosure (3). The lab results will be provided to NNSY representatives (Code 930/906) on machines that do not meet the acceptable coolant recycling / recharging criteria as listed below:

COOLANT RECYCLING CRITERIA

Bacteria

None

Fungi

None

COOLANT RECHARGING CRITERIA

Bacteria

Fungi

3. When the coolant recycling standards fall out of the specified acceptable range Contractor will be responsible for removing the old coolant and providing replacement coolant or recycling the old coolant using the coolant recovery machine located in Shop 31.

NOTE: The contractor shall be responsible for the maintenance and upkeep of the coolant recovery system (machine ID 181-046991) located in Building 171-1-F06, employed to accomplish coolant recycling duties.

4. Develop and utilize a clean-out data sheet for each machine similar to the sample provided in Enclosure (4). The date sheet shall list the following information:

a. Date service was accomplished.

b. Whether tramp oil was removed and approximate quantity.

c. Initial refractometer reading.

d. Whether water or concentrate was added in order to achieve 5-7% coolant concentration.

e. Final refractometer reading.

f. Service representative signature who performed the work.

NOTE: The contractor will ensure the monitoring results listed in the data sheet are attached to each machine for inspection purposes.

5. Remove all waste liquid 7 materials generated during the execution of the duties associated with this contract.

B.

1. NNSY will provide the contractor mutually agreed upon lockable storage space for coolant / supplies on the first floor of Building 171 adjacent to the coolant recovery system and a satellite accumulation area for the hazardous waste is applicable.

NOTE: The contractor will be responsible for maintaining these areas in a neat and orderly fashion.

2. NNSY will notify the contractor within 24 hours of contaminating coolant with phenolic, rubber, etc. to request coolant change-out. (Not to Exceed six (6) requests or 200 gallons per year). Contractor will complete the coolant change-out within 24 hours of notification.

3. Contractor will provide 500 gallons (minimum) of premixed coolant (5-7%) to shop personnel for emergent coolant use during peak work operations & weekends.

4. Contractor will meet with applicable NNSY representative to discuss and resolve Coolant maintenance issues on a monthly or as-needed basis.

5. Contractor will be responsible for circulating the coolant for one (1) hour bi-weekly on equipment designated by NNSY as low usage (Not to Exceed 15% of total machines listed).

6. All coolant inventory (HOCUT 795) and related products will be provided and owned by the contractor.

Cleaning Procedure

1. Remove all swarf and debris from sump; return trenches, oil pans and filtration units.

2. Add one (1) gallon CIMCLEAN 30 or HOCUT SYM-C (or equivalent metal working cleaner. MUST BE APPROVED BY SHOP 31 PRIOR TO USE) per 50 gallons of dirty coolant.

3. Circulate for four (4) hours through ALL coolant lines. Brush all trenches and filter elements, scrub machine, oil pans and exposed surfaces.

4. When physical cleaning is complete, drain the metal working cleaner from the system.

5. Fill to capacity with fresh water to remove all traces of cleaner.

6. REMOVE ALL RINSE WATER.

7. If rinse water is exceptionally dirty, rinse a second time. Lack of thorough cleaning will cause coolant to become rancid and require re-clean and fresh charge of coolant.

8. Charge system with virgin premixed coolant 5-7% HOCUT 795.

9. Circulate through system to ensure proper mix.

10. Contractor shall turn in all waste described in Code 106 OSHE Program Manual Chapters II-38 and II-45.

Weekly Monitoring Procedures using Houghton International HOCUT 795 Coolant

1. Skim Tramp Oil etc. from coolant

2. Check refractometer

3. If refractometer is above 7% concentration, fill sump with water to capacity.

4. If refractometer is below 5% concentration, fill sump from Charge Buggy with1-% premix to capacity (1% premix subject to change).

5. Recheck refractometer and record readings.

6. If below 5% again, add concentrate ONLY.

7. Recheck refractometer and record all readings on data sheet.
