Request for Proposal

LNG Tank Exterior Painting

Norwich Public Utilities (NPU) is requesting proposals from qualified contractors to repaint NPU’s 55,000 gallon LNG (liquified natural gas) storage tank located at 10-12 Wisconsin Avenue, Norwich, CT. Included in the work is the proper removal and disposal of lead and PCB’s, as described in the attached Remediation Specifications.

The NPU LNG storage tank is cryogenically designed to store LNG inside at -260 degrees F and at 60-65 psig. The tank is a double containment tank, with one tank inside another.

The inner tank, constructed of aluminum, is a pressure vessel, designed to hold LNG at a maximum pressure of 90 psig. The outer tank is a carbon steel support tank. Between the two tanks is an annular space which varies in width from 8 ½” around the outside to 12” at the tank ends. The annular space is filled with perlite granular insulation and then highly evacuated.

In compliance with Occupational Safety and Health Administration (OSHA) requirements, an environmental assessment of the existing tank was performed and the presence of hazardous Polychlorinated Biphenyl (PCB) and Lead levels were detected on the tank surface. Using lead-based paint chip sampling, the paint on the LNG tank and cradle was identified to have greater than 0.50% lead content by weight and is therefore classified as Lead-Based Paint (LBP). Additionally, all painted metal surfaces returned >50 PPM on PCB-containing materials.

Below is brief summary of the project specifications, personnel certifications, and qualifications required to be considered for the project.

A. The Contractor shall provide plans and calculations detailing the proposed method of containment and ventilation. The plans shall include an elevation view of the containment enclosure clearly showing any encroachments on the surroundings.

B. The plans shall contain details of the method of sealing joints, the entrance/exit openings, air intake points (including filters, louvers, and baffles), type/placement of lighting systems, and connections to the structure. Methods of attachment that require welding, drilling, bolting, or any methods requiring alteration of the structure or part of it, are not allowed.

C. If the containment will be attached or connected to the LNG Tank structure in anyways, the Contractor shall analyze the Structure to determine its ability to safely support the proposed containment system and equipment. The following calculations are required:

a. The maximum dead and live load imposed on the LNG structure by the containment system.

b. The maximum allowable load for any floors/platforms.

c. The calculations shall include an analysis of the stresses in all affected members and applicable load rating capacities.

D. Any containment system attached or connected to the LNG Tank Structure shall be analyzed to determine the amount of stress applied to the structure as a result of wind loads on the containment. The Contractor shall calculate an “allowable wind speed” which will be used, in the field, to determine the threshold for dismantling the containment system.

1.5.4.2 MATERIAL REǪUIREMENTS

A. All tarps, drapes and plastic sheeting materials used for containment or ground cover shall be fire-retardant and impermeable to air and water. All materials shall be in good condition.

1.5.4.3 LIGHTING

A. Light at the work substrates within the containment enclosure shall be maintained by the

Contractor at a minimum of 30 fc as measured by a light meter. Such lighting shall be maintained throughout the surface preparation, painting, and inspection activities. The use of explosion-proof lighting is mandatory.

B. The Contractor shall maintain, as fully operational and functional, all existing lighting systems including navigation lights, aerial lighting, and roadway or parking lot lighting and signage.

LNG TANK PAINTING

C. If existing lighting will be concealed, the Contractor shall install temporary lighting and a temporary lighting plan shall be required to be included in the Contractor’s submittals for review and approval by the Owner C Engineer in advance of the work.

1.5.5 FIELD OPERATIONS

A. All debris and abrasive, which have accumulated, as the result of surface preparation shall be vacuum cleaned at a frequency specified in the Contractor’s containment submittal, or more frequently if directed by the Engineer. Prior to removal or relocation to another point along the structure, all debris must be removed from the containment materials and equipment. The level of cleanliness shall be such that wind or physical contact during handling and transportation does not dislodge debris or dust.

1.5.6 VENTILATION

A. When negative pressure is required within a containment system, the designed system shall maintain a minimum negative pressure as measured by 0.76 mm (0.03 in.) of water column relative to external ambient air. Air velocity within the enclosure shall meet the minimum requirements of 30 m/min (100 ft/min) cross draft and 18 m/min (60 ft/min) downdraft. Submittals shall include a description of the dust collection and filtration equipment, including the equipment data sheets and airflow capacity.

1.5.7 HANDLING OF HAZARDOUS WASTE AND REPORTING RELEASE PROGRAMS

A. The Contractor shall submit a plan to the Engineer detailing all aspects of waste management including an Emergency Response Contingency Plan. The plan shall detail the methods for the collection, handling, sampling, testing, site storage, and disposal of wastewater, lead paint, and related debris. The Contractor and the Owner are the co-generators of the waste. The Owner will provide the EPA identification number and the

Contractor is responsible for all other waste management.

1.5.7.1 WASTE SAMPLING, TESTING AND CLASSIFICATION

A. All waste streams generated as part of the work shall be tested by TCLP for all eight

RCRA metals, PCBs, pH, flash point, ignitability, reactivity, corrosivity, and percent solids to determine proper disposal. The Engineer shall be the final authority on what shall be tested for possible contamination. Four samples representative of each waste stream shall be collected and tested in accordance with EPA SW846 Method 1311.

B. The Engineer must be notified of the date and time of sample collection prior to sampling activities. The Contractor, in the presence of the Engineer, shall perform sampling for testing and a State certified laboratory shall perform testing. Chain of custody must be adhered to for sample removal. TCLP test results certified by the testing laboratory shall be provided to the Engineer. The following information must be contained in the laboratory report as a minimum:

b. Identification of the waste stream analyzed

c. Number of samples collected and tested

d. Dates of sampling and testing

e. Defined laboratory test procedures

f. The names and signatures of sampling technicians and laboratory technicians

g. Summary of test results

C. The Contractor shall provide the Engineer with an original signed copy of the report no later than 14 days after the samples have been collected.

D. Non-hazardous waste shall not be mixed with hazardous waste. DEEP requires that a mixture of non-hazardous waste with hazardous waste must be treated as hazardous.

E. All debris cleaned and collected from abutments and other areas of collection shall be disposed of properly. Debris which include, but not limited to, sand, gravel, bituminous materials and bird excrement shall be packaged and stored separately from waste generated as a result of surface preparation. A representative sample of the debris shall be analyzed to determine its classification prior to disposal.

1.5.7.2 WASTE HANDLING, PACKAGING, AND STORAGE

A. Lead paint and related debris must be collected daily and placed in DOT approved containers of good integrity (i.e., no dents, holes, missing lids or locking mechanisms, etc.)

B. The Contractor shall inspect drums weekly and the results recorded in an on-site logbook accessible to the Engineer. Containers shall be closed and clearly labeled to identify the contents. Hazardous wastes must be labeled with the words “HAZARDOUS

WASTE,” the name of the waste, the hazards associated with the waste, and the date when accumulation began in the container. The hazardous waste label shall also include the generators’ name, address, and EPA identification number.

C. Containers shall be stored in a safe and suitable location at the job site. Storage shall be in a manner that protects the public and the environment, i.e., on a level impervious base, away from waterways, etc. Storage area(s) shall be approved by the Owner C Engineer prior to generating wastes.

D. Storage areas shall be labeled with the words “HAZARDOUS WASTE” Appropriate security (i.e., fencing, locked gated, etc.) must be maintained at the site to avoid injury, theft or vandalism with regards to hazardous waste. Once a container in the work area is full, it shall be moved to the secure storage area within 3 days. If a suitable location for hazardous waste storage does not exist on-site, the Contractor shall find an alternate storage site. The alternate storage site shall only be allowed with documented permission by the Engineer and DEEP. Evidence of improper storage and handling

LNG TANK PAINTING

shall be cause for immediate shutdown until corrective action is taken.

E. Storage of hazardous waste on site is limited to 90 days with the start date of initial accumulation in each container. The Engineer is to be informed one week in advance of the planned date(s) when hazardous waste is to be removed from the job site.
