Specification Feedback

The intent of this section is to inform all users that a spec feedback mechanism is in place, and is located on the MLCA Naval Engineering Division’s website. Spec feedback is a very important part of our overall continuous improvement process, and is crucial to specification development. It will allow spec writers to capture all specification-related lessons learned, and avoid mistakes or ambiguities in follow-on availabilities. All feedback will be reviewed, evaluated, and responded to in a timely manner.

If you have access to the CGWeb (Intranet), please use the following link, which will connect you to the MLCA(v) Naval Engineering website, for submitting your feedbacks:

http://webapps.mlca.uscg.mil/vdiv/specifications/feedback/default.cfm If you do not have access to the CGWeb (Intranet), you may still submit your feedbacks, using the following web link:

ASTM International (ASTM) D1330, 2000, Standard Specification for Rubber Sheet Gaskets

3. REQUIREMENTS

3.1 General. The Contractor shall clean the sewage and grey water piping systems using Coast Guard Drawing 240 WLBB 528-001 and 240 WLBB 593-001 as guidance.

3.2 Contamination prevention. The Contractor shall take all precautions to prevent contamination of personnel and spaces in accordance with all applicable Federal, state, and local regulations.

3.3 Cleaning plan. The Contractor shall establish a plan for cleaning the designated sewage and grey water piping system, listing the step by step procedures necessary to ensure that all foreign debris is removed from the piping system.

NOTICE!

Although the Coast Guard prefers hydro-blasting as the cleaning method, the Contractor may propose chemical cleaning as an alternative, providing that the proposed chemical cleaning agent conforms to DOD-STD-2187 (where applicable), is environmentally safe, and pre-approved by the COR. Due to the fact that sewage system piping has historically been difficult to clean by hydro-blasting, chemical cleaning is usually required to successfully complete the cleaning process. Provide MSDS for all proposed Chemical Cleaning Agents.

3.3.1 Procedure requirements. Ensure that the procedure includes the following:

· Methods of cleaning.

· All safety precautions required during cleaning operations.

· List of qualified personnel who will operate machinery or handle chemicals (see paragraph 4.2 (Personnel qualification) herein).

· Locations in the sewage and grey water piping where cleaning will take place, and any additional fittings necessary.

· Sequence of each location that ensures all piping sections will be cleaned and all foreign debris removed.

3.3.2 Plan submittal. Submit the written plan to the COR for approval at least two (2) working days prior to commencing cleaning operations.

3.4 Cleaning operations. Upon approval of the plan, the Contractor shall proceed with the cleaning of all horizontal and vertical runs of the piping system, as follows:

3.4.1 Valves. Replace sewage tank valve(s) with temporary spool piece(s). Visually inspect the valve(s), and submit a CFR. Upon completion of work, reinstall the valve(s).

3.4.2 Cleaning. Do the following:

· If hydro-blast cleaning, provide a high-pressure water jetting machine which can attain suitable flow pressures to remove all calcium carbonate deposits and buildup.

· Clean out piping at no more than 25-foot intervals.

· Continue cleaning until discharge water from the piping being cleaned is free of all visible scale and deposits.

· Inspect the piping interior using a bore scope in the presence of the COR, to verify that all solid deposits have been removed. Continue the cleaning process until all solid deposits are removed from the pipe walls.

3.4.3 Waste disposal. Dispose of all cleaning fluids and debris in accordance with all applicable Federal, state, and local regulations. Remove all unused chemicals from USCG property immediately upon completion of work item.

WARNING!

Do not drain any fluids (including fresh water) into any space, bilge, or exterior location.

3.5 Gasket and fastener renewal. The Contractor shall reinstall all removed valves and fittings with new gasket material conforming to ASTM D1330.

4. QUALITY ASSURANCE

4.1 Leak test. After all system components are reinstalled, the Contractor shall test all disturbed sewage system and grey water piping for leakage, as follows:

· Plug all system openings (except the highest) and fill system with water to the point of overflow. Ensure that the water level does not go down (without adding any water) for sufficient time to inspect the entire system (no less than 15 minutes).

· Closely monitor the system for leaks. Repair all leaks detected.

· Repeat test and inspection until no leaks are detected.

4.2 Personnel qualification. The Contractor shall ensure that personnel accomplishing this work are qualified and experienced in operating the pressurized water system and handling the chemicals. For each operator/cleaning technician, submit documentation of applicable experience and training obtained within the last twelve months along with the Cleaning Plan (see 3.3.2, Plan Submittal).
