Reporting requirements must be in accordance with Section 02 65 00 UNDERGROUND STORAGE TANK REMOVAL.

1.16 MATERIALS TRANSFER SAFETY

Remove liquids and residues from the tanks using explosion-proof or air-driven pumps. Bond to the tank and ground pump motors and suction hoses to prevent electrostatic ignition hazards. Use of a hand pump will be permitted to remove the last of the liquid from the bottom of the tanks. If a vacuum truck is used for removal of liquids or residues, the area of operation for the vacuum truck must be vapor free. locate the truck upwind from the tank and outside the path of probable vapor travel.

Discharge the vacuum pump exhaust gases through a hose of adequate size and length downwind of the truck and tank area. Vacuum truck operating and safety practices must conform to API RP 2219. Collect tank residues in drums, tanks, or tank trucks labeled according to 49 CFR 171 and 49 CFR 172 and disposed of as specified. Disconnect and drain fittings and lines of their contents after the materials have been transferred and the tanks have been exposed. Do not spill contents into the environment during cutting or disconnecting of tank fittings. Transfer materials drained into DOT-approved drums for storage and/or transportation. Only non-sparking or non-heat producing tools shall be used to disconnect and drain or to cut through tank fittings. Electrical equipment (e.g., pumps, portable hand tools, etc.) used for tank preparation must be explosion-proof. Following cutting or disconnecting of the fittings, plug openings leading to the tanks.

1.17 HOT WORK

Hot work will not be permitted on or within the tanks or anywhere else not previously specified as a hot work area, except as outlined herein. Prior to conducting hot work, a hot work permit must be prepared by the person to be conducting the hot work and reviewed and signed off by the Contractor's qualified person. An additional hot work permit may need to be obtained from local authorities or in the case of military or other federal installations, the fire marshal. An example format for a hot work permit must be included in the AAPP/SSHP. Describe compliance with the following procedures. After tank interiors have been decontaminated, hot work may be conducted only when the tank is inerted, and to the extent necessary to

SECTION 01 35 29.13 Page 10 begin dismantling the tanks. After decontamination of tank interiors, hot work must not be performed unless monitoring indicates atmospheres within and immediately surrounding the tanks are less than 8 percent oxygen inside the tank and less than 10 percent of the LFL outside the tank; continuous monitoring must continue until the hot work is completed. The hot work prohibition includes welding, cutting, grinding, sawing, or other similar operations which could be expected to potentially generate combustion-producing temperatures or sparks, or which could produce potentially hazardous fumes or vapors. Designate an individual at each hot work site as a fire watch. This person's sole responsibility is to monitor the hot work and have immediate access to the fire extinguisher located at each hot work site. A new permit must be obtained at the start of each work shift during which hot work will be conducted.

1.18 TANK PURGING FOR PERMIT-REQUIRED CONFINED SPACE ENTRIES

Purge tanks for confined space entry. Reduce the flammable vapors to less than 10 percent of the LFL and the oxygen content be between 19.5 percent and 23.5 percent. Do not attempt confined space entry into the tanks unless absolutely necessary, as for example, to remove sludge from the tank. Flammable vapors may be exhausted from the tank by any of the methods from API RP 1604 listed below, or any method approved by the Contracting Officer. Specify the purging method to be used within the

APP/SSHP.

1.18.1 Ventilation by Eductor-Type Air Movers

Properly bond and ground the eductor-type air mover to prevent the generation and discharge of static electricity. When using this method, the fill (drop) tube must remain in place to ensure ventilation at the bottom of the tank. Tanks equipped with fill (drop) tubes that are not removable must be purged by this method. Use an eductor extension to discharge vapors a minimum of 12 feet above grade or 3 feet above adjacent roof lines, whichever is greater. If this is not possible, propose and get approved alternative methods prior to purging. Noise levels generated by these devices as a result of high airflow may exceed OSHA PELs. Evaluate noise levels and provide appropriate hearing protection.

1.18.2 Ventilation by Diffused Air Blowers

When using this purging method, the air-diffusing pipe is properly bonded and grounded to prevent the discharge of a spark. Fill (drop) tubes must be removed to allow proper diffusion of the air in the tank. Air supply must be from a compressor that has been checked to ensure that Grade D breathing air is being supplied. Air pressure in the tank must not exceed 5 psi gauge to avoid tank failure.

1.18.3 Commercial Emulsifiers and Volatile Fuel Encapsulators

These products are completely miscible in water, aid in the elimination of flammable vapors, and are biodegradable. Determine prior to using this method, regulatory requirements for treatment and disposal of the water.

Standing outside the tank, rinse the tank with a 3-to-6 percent solution of the product using a pressure sprayer through a tank opening. Measure explosive concentrations at several levels (top, middle, and bottom) within the tank. If readings are greater than 10 percent of the LFL, rinse the tank again. When LFL readings are acceptable, pump the water in the tank for disposal.

SECTION 01 35 29.13 Page 11

1.19 TANK INERTING (NO ENTRY)

Following the removal of tank contents but prior to removal of the tank(s) and tank preparation activities, inert the tank(s) only by introducing an inert gas, carbon dioxide (CO2) or liquid nitrogen (N2), to remove flammable vapors. Before inerting, plug all openings in the tanks with threaded or expansion type plugs except the vent tube and the opening to be used for introducing the inert gas. Within 30 minutes prior to initiating any activities (e.g., excavating, preparation, removal, opening, demolition, transportation, or other similar activities) involving a tank which has been inerted, the inerted nature of the tank (oxygen levels less than 8 percent) must be verified.

a. Do not use CO2 fire extinguishers for inerting the tank interiors. If a compressed gas (e.g., CO2 or N2) is introduced into the tank the following requirements must be met to prevent the buildup of static electricity:

(1) Bond together and ground the UST and the compressed gas supply tank.

(2) Supply the compressed gas only at low flows.

(3) Release the liquid or gas at the tank bottom so that static electricity is not generated by liquid falling to the bottom of the tank. Slowly fill the tank from the bottom up.

b. If used, introduce dry ice, which evolves CO2 gas as it evaporates, in the amount of at least 3 lbs per 100 gallons of tank capacity. Prevent skin contact with dry ice by wearing heavy cloth gloves.

c. Introduce sufficient quantities of inert gas (CO2 or N2) into the tanks to lower the oxygen content to less than 8 percent. Do not exceed 5 psi pressure inside the tank. Prior to proceeding with additional activities on the tank (e.g., excavating), the oxygen content of the tanks must be monitored to confirm that it is less than 8 percent.

Conduct additional oxygen level monitoring at least hourly while activities involving the tanks are underway but prior to decontamination of tank interiors; at least daily during periods in which the tanks are not being disturbed but prior to decontamination of their interiors; or as directed by the Contracting Officer. If monitoring of tank interiors indicates that oxygen levels are not remaining below 8 percent, introduce additional inert gas and initiate more frequent oxygen monitoring.

d. During inerting procedures, use an extension vent tube a minimum of 12 feet above grade or 3 feet above any adjacent (within 75 feet) roof lines, whichever is greater to discharge tank vapors. If this is not possible, propose and get approved alternative methods prior to inerting. Conduct continuous combustible gas/oxygen monitoring shall be conducted at the vent and inert gas introduction holes.

1.20 TANK ATMOSPHERE TESTING

Monitor the air within the storage tanks to ensure the space is either adequately purged and safe for personnel entry, or to ensure the tank has been adequately inerted and the oxygen content is less than 8 percent. In both instances, perform monitoring at the top, bottom, and middle areas of the tanks to ensure stratification has not occurred. Report monitoring

SECTION 01 35 29.13 Page 12 results to project personnel to ensure safe operations. Record data as specified in paragraph EXPOSURE MONITORING/AIR SAMPLING PROGRAM.

1.20.1 Monitoring to Ensure Purging

When monitoring to ensure purging, both oxygen content and LFL readings are required. Prior to obtaining LFL readings, monitor the oxygen content of the space and verify that the combustible gas indicators are operating within the oxygen limits identified by the CGI manufacturer. Do not permit personnel to enter spaces with oxygen levels are less than 19.5 percent, except in emergencies, and then only when equipped with the proper PPE and when following permit-required confined space entry procedures. Monitor toxic air contaminants as specified in paragraph EXPOSURE MONITORING/AIR

SAMPLING PROGRAM.

1.20.2 Monitoring to Ensure Inerting

Monitor inerted tanks to ensure oxygen readings remain below a maximum allowable percentage of 8 percent by volume.

1.21 TANK LIFTING

Lift tanks using equipment with a rated capacity greater than the load to be lifted. Lift tanks by lifting eyes or by straps under the ends of the tanks. Do not lift by the manhole flange or by removing the bungs. Direct personnel to remain away from the ends of the tanks and position tanks , whenever possible, with the ends oriented away from occupied or traveled areas, due to potential for rupture. During transportation, secure the tanks to prevent movement.

1.22 TANK DEMOLITION

Demolish excavated tanks before being removed from the site unless they are transported directly to a state certified tank destruction facility.

Demolition will not be permitted until a decontamination of the interiors and exteriors is complete. Demolition must involve opening the tanks sufficiently to permanently prohibit further use as containers of liquids.

Tanks must be inerted and tested before they are opened. Submit plans and procedures in the APP/SSHP, including a list of materials and supplies, for safely and effectively demolishing the tanks.

1.23 TANK CLEANING

conform to API Std 2015 for safety practices and procedures for the cleaning of the storage tanks. Conduct opening of the tanks to permit decontamination utilizing only methods approved in the APP/SSHP.

Decontaminate the interior and exterior of the tank prior to removing it from the work site unless the tank is being transported directly to a state certified tank destruction facility. Submit plans and procedures in the SSHP, including materials and supplies, for safely and effectively opening the tanks, cleaning surfaces of the interior and exterior of the tanks, and disposing of the decontamination fluids. Volatile organic solvents are not permitted to be utilized for decontamination procedures. Personnel must not enter any of the storage tanks as a part of this project, except when following permit-required confined space entry procedures. Collect and dispose of decontamination fluids. Upon completion of this project, written certification must be made that the tank was properly decontaminated prior to being removed from the site.

SECTION 01 35 29.13 Page 13

1.24 SITE CONTROL MEASURES

1.24.1 Work Zones

Initial anticipated work zone boundaries (exclusion zone, contamination reduction zone, support zone, all access points and decontamination areas) are to be clearly delineated on the site drawings. Base delineation of work zone boundaries on the contamination characterization data and the hazard/risk analysis to be performed as described in paragraph: HAZARD/RISK ANALYSIS. As work progresses and field conditions are monitored, work zone boundaries may be modified (and site drawings modified) with approval of the Contracting Officer. Clearly identify work zones and marked in the field (using fences, tape, signs, etc.). Submit and post a site map, showing work zone boundaries and locations of decontamination facilities in the onsite office. Work zones must consist of the following:

1.24.1.1 Exclusion Zone (EZ)

The exclusion zone is the area where hazardous contamination is either known or expected to occur and the greatest potential for exposure exists.

Control entry into this area and exit may only be made through the CRZ.

The CRZ is the transition area between the Exclusion Zone and the Support Zone. The personnel and equipment decontamination areas must be separate and unique areas located in the CRZ.

1.24.1.3 Support Zone (SZ)

The Support Zone is defined as areas of the site, other than exclusion zones and contamination reduction zones, where workers do not have the potential to be exposed to hazardous substances or dangerous conditions resulting from hazardous waste operations. Secure the Support Zone against active or passive contamination. Site offices, parking areas, and other support facilities must be located in the Support Zone.

1.24.2 Site Control Log

A log of personnel visiting, entering, or working on the site must be maintained. Include the following: date, name, agency or company, time entering and exiting site, time entering and exiting the exclusion zone (if applicable). Before visitors are allowed to enter the Contamination Reduction Zone or Exclusion Zone, they must show proof of current training, medical surveillance and respirator fit testing (if respirators are required for the tasks to be performed) and fill out a Certificate of Worker or Visitor Acknowledgment. Record this visitor information, including date, in the log.

1.24.3 Communication

Provide and install an employee alarm system that has adequate means of on and off site communication in accordance with 29 CFR 1910 Section .165.

The means of communication must be able to be perceived above ambient noise or light levels by employees in the affected portions of the workplace.

The signals must be distinctive and recognizable as messages to evacuate or to perform critical operations.
