Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the procedures for cleaning and flushing hydronic piping systems to remove deleterious substances.

• Cleaning and Flushing: Remove organic soil, hydrocarbons, flux, pipe mill varnish, pipe compounds, iron oxide, and similar substances. Removal of tightly adherent mill scale is not required.

• Delivery, Storage, and Handling: Detergent must be handled and stored according to manufacturer's recommendations to protect equipment, environment, and persons.

• Environmental Requirements: All chemicals used must be acceptable for discharge into the sanitary sewer.

• Submittals: Specific submittals are required, including product data for cleaning detergent and water treatment chemicals, and information on the chemical supplier. These must follow Section 01 33 00 SUBMITTAL PROCEDURES.

• Materials: The cleaning compound/detergent shall be an alkaline phosphate or non-phosphate detergent/surfactant suitable for system wetted metals. It should not contain corrosion inhibitors other than sodium sulfite (oxygen scavenger). Trisodium phosphate is suggested.

• Water Treatment: Sodium sulfite, sodium lauroyl sarcosinate, and dipotassium phosphate are used for water treatment.

• Execution - Protection: Do not exceed the service factor amperage on the pump motor.

• Execution - Special Techniques:

  • Maintain water temperature at 120°F using the existing steam heating system.
  • Bypass terminal units by closing service valves and opening bypass valves, or using three-way valves.
  • Fill the system with water and detergent solution to the manufacturer's specified concentration and heat to 120°F.
  • Circulate the solution for a minimum of 48 hours, maintaining 120°F, while periodically cleaning strainers.
  • Flush each terminal device after ensuring strainers are clean.
  • Drain the system and flush thoroughly with fresh water until the water runs clear.
  • Treat the water to specific chemical parameters: Sodium sulfite (30-100 ppm), Sodium lauroyl sarcosinate (30-100 ppm), and pH (8.5-9.5).
  • Retest chemical levels one day, one week, and four weeks after initial treatment, conducting additional treatment if necessary.
  • Prepare and submit a report documenting water system volume, pH, and sulfite concentration levels.
  • Provide Material Safety Data Sheets (MSDS) for treatment chemicals and permanently locate a copy in each mechanical room.
  • Provide a plastic sign (minimum 12"x12") in each mechanical room stating the system volume and required chemical parameters.

Not explicitly stated in this section, but implied to be on-site at Camp Lejeune.

• Chemical acceptability for sanitary sewer discharge.
• Specific chemical concentrations and pH levels for water treatment.
• Reporting requirements for water treatment and chemical levels.
• Provision of MSDS and informational signage.

This document is the "Contractor Environmental Guide" for Marine Corps Base Camp Lejeune, dated September 2023. It provides comprehensive guidance to contractors on environmental regulations, policies, and procedures applicable to work performed aboard MCB Camp Lejeune and MCAS New River.

This guide is crucial for any contractor planning to perform work at MCB Camp Lejeune. It outlines:

• Environmental Management System (EMS): Explains the installation's EMS and contractor responsibilities.
• Specific Environmental Areas: Details requirements for Air Quality, Environmental Emergency Planning and Response, Cultural Resources, Hazardous Materials/Waste Management, Asbestos, Lead-Based Paint, Natural Resources, Stormwater, Solid Waste/Recycling/Pollution Prevention, Potential Discovery of Undocumented Contaminated Sites, Permitting, and Temporary Construction.
• Training Requirements: Mandates general environmental awareness and EMS training for all personnel.
• Points of Contact: Provides essential contact information for various environmental programs and emergency situations.
• Regulatory Compliance: Emphasizes the contractor's responsibility to comply with all Federal, State, and local environmental laws and regulations.

Contractors must review this guide to understand and adhere to all environmental requirements to ensure compliance and avoid potential penalties.
