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

NOTE

Although the Coast Guard prefers pressurized water as the cleaning fluid, 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 COTR. Due to the fact that sewage system piping has historically been difficult to clean by pressure washing only, chemical cleaning is usually required to successfully complete the cleaning process. The Contractor shall submit a MSDS to the COTR for all chemicals proposed for use.

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 3.8 (Personnel qualification) herein).

· Locations in the 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.
