1.0 INTRODUCTION

1.1 Site Description

The project consists of six structures at the Rincon Forest Fire Station located at 16971 Highway

76 in Pauma Valley, California. The Site is depicted on the Vicinity Map (Figure 1), Site Plans

(Figures 2 through 4), and in the Site Photographs.

1.2 Objective

The work procedures and requirements described herein are provided for: 1) the removal of regulated asbestos-containing materials (RACM – i.e., cementitious exterior tiles) and deteriorated (peeling/flaking) lead-containing paint (LCP); 2) the handling of universal wastes; and 3) the disturbance of intact LCP during demolition activities at the Site.

1.3 Background

Geocon completed an asbestos, LCP, and universal waste survey of the Site on June 27, 2017.

The findings are presented in Geocon’s Asbestos, Lead-Containing Paint, and Universal Waste Survey

Report, dated July 28, 2017.

Chrysotile asbestos at concentrations greater than 1% was identified in the following materials used in the barracks/mess hall/garage:

Approximately 250 square feet of nonfriable cementitious exterior tiles (RACM); and

Approximately 3,500 square feet of nonfriable floor tile systems (non-RACM).

Asbestos sample group identification numbers, material descriptions, locations, approximate quantities, friability assessments, and photo references are summarized in Table 1. Sample locations are presented on the Site Plans.

Samples representing suspect LCP sampled during our survey exhibited total lead concentrations ranging from less than (<) 4.4 to 150,000 milligrams per kilogram (mg/kg). Additional composite analysis of seven samples with total lead concentrations greater than 1,000 mg/kg exhibited a representative Toxicity

Characteristic Leaching Procedure (TCLP) lead concentration of 110 milligrams per liter (mg/l). Lead is assumed to be present in all paints at the Site.

Deteriorated white LCP identified on the garage interior (approximately 20 square feet) and the shed electrical panel (approximately 40 square feet) would be considered a California and Federal hazardous waste based on lead content. As such, the deteriorated paints must be removed and disposed of prior to demolition.

Geocon Project No. A8575-06-21 -2- July 28, 2017

Paint sample identification numbers, paint descriptions, locations, approximate peeling/flaking quantities, and photo reference are summarized in Table 2. Sample locations are presented on the Site Plan, Figure 2.

Fuel tanks (liquid and propane) were observed at the Site. A total of approximately 26 fluorescent and sodium lighting fixtures were observed in the barracks/mess hall/garage, exterior areas, and hose rack.

Various household chemicals (lubricants, solvents, refrigerants, cleansers, paints, etc.) were observed in the

Barracks/mess hall/garage and shed. An inventory of observed universal wastes and suspect hazardous materials is presented in Table 3.

California Department of Toxic Substances Control (DTSC) hazardous waste regulations contained in Title 22, CCR, Division 4, Chapter 30.

Removal of RACM and activities performed in conjunction with demolition of non-RACM flooring will disturb asbestos with the potential to result in worker exposure to airborne asbestos fibers.

The General Contractor and sub-contractors, hereafter collectively referred to as the “Contractor,” shall take necessary precautions to prevent or minimize the release of asbestos fibers into the air or into surrounding environments. The Contractor shall inform all workers and supervisory personnel who will be at the Site of the potential hazards of asbestos and of necessary precautions and housekeeping procedures to reduce the potential for exposure in areas where asbestos is known to be present.

Geocon Project No. A8575-06-21 -3- July 28, 2017

The Contractor shall be responsible for compliance with the Cal/OSHA asbestos standard as contained in Title 8, CCR, §1529. This regulation establishes requirements, including initial personal air monitoring, whenever any information, observation, or calculation indicates potential employee exposure to asbestos. If eight-hour time-weighted average (TWA) exposures exceed the permissible exposure limit (PEL) of 0.1 fibers per cubic centimeter (f/cc) of air, the Contractor shall stop work and implement more stringent and additional requirements, such as engineering controls and increased respiratory protection in asbestos work areas. The Contractor shall also perform Cal/OSHA pre-job notification as required in Title 8, CCR, §341.9.

The requirements specified in this document pertaining to training, medical surveillance, hygiene facilities, containment, methods of compliance, etc. are based on the presumption that the Contractor, through the use of work practice controls, will be able to maintain exposures to airborne asbestos fibers below the Cal/OSHA worker 8-hour TWA PEL of 0.1 f/cc and the 30-minute excursion limit of 1 f/cc.

The Contractor shall possess negative exposure assessments (NEAs) for similar work performed within the past 12 months, or perform initial personal air monitoring.

If worker exposures are found to exceed the Cal/OSHA worker 8-hour TWA PEL or the 30-minute excursion limit, work shall cease and work methods shall be revised.

1.4.2 Lead

Contractors performing lead-related work activities necessary to facilitate demolition are required to comply with the following regulations:

Cal/OSHA lead standard for the construction industry contained in Title 8, CCR, §1532.1;

California DPH lead regulations contained in Title 17, CCR, Division 1, Chapter 8;

Because this is not a lead abatement project designed to reduce lead hazards for a public or residential building, the only DPH regulatory (Title 17) condition that applies to the demolition work is the requirement for use of containment as defined in the United States Environmental Protection Agency (USEPA) Department of Housing and Urban Development (HUD) “Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing.”

Respiratory Protective Equipment Standard (Title 8, CCR, §5144);

Hazard Communication Standard (Title 8, CCR, §5194);

US DOT, Title 49 CFR, Parts 171 through 180; and

California DTSC hazardous waste regulations contained in Title 22, CCR, Division 4, Chapter 30.

Geocon Project No. A8575-06-21 -4- July 28, 2017

Deteriorated LCP removal and other activities performed in conjunction with demolition will disturb

LCP with the potential to result in worker exposure to airborne lead. The Contractor and shall take necessary precautions to prevent or minimize the release of lead in the form of dust, fumes, or mists from

LCP into the air or into surrounding environments. The Contractor shall inform all workers and supervisory personnel who will be at the Site of the potential hazards of lead and of necessary precautions and housekeeping procedures to reduce the potential for exposure in areas where lead is known or suspected/assumed to be present.

The Contractor shall be responsible for compliance with the Cal/OSHA lead standard as contained in

Title 8, CCR, §1532.1. In addition to Cal/OSHA pre-job notification requirements, this regulation establishes other requirements, including initial personal air monitoring, whenever any information, observation, or calculation indicates potential employee exposure to lead. If 8-hour TWA exposures exceed the action level of 30 micrograms of lead per cubic meter (g/m3) of air, the Contractor must continue to conduct periodic air monitoring at specified intervals, institute medical surveillance, and initiate a comprehensive training program. If the Cal/OSHA 8-hour TWA PEL of 50 g/m3 is exceeded, more stringent and additional requirements become effective, such as engineering controls, increased respiratory protection, regulated work areas, and warning signs in lead work areas, in addition to

California DPH lead-related construction certification for all workers and supervisors disturbing lead.

The requirements specified in this document pertaining to training, medical surveillance, hygiene facilities, containment, methods of compliance, etc. are based on the presumption that the Contractor, through the use of work practice controls, will be able to maintain worker 8-hour TWA exposures to airborne lead below the Cal/OSHA action level of 30 g/m3. The Contractor shall provide respiratory protection and perform initial personal air monitoring for workers performing “trigger tasks” as defined in Title 8, CCR, §1532.1(d). If worker exposures are found to exceed the action level, additional and more stringent requirements will become effective as detailed in the Cal/OSHA lead-in-construction standard. Work shall cease and work methods shall be revised to reflect those requirements in the event that employee exposures exceed the action level. Respiratory protection shall be required until airborne lead levels are demonstrated to be below the Cal/OSHA action level.

Geocon Project No. A8575-06-21 -5- July 28, 2017

1.4.3 Universal Waste

Contractors performing universal waste and potential hazardous materials removal activities necessary to facilitate building demolition are required to comply with the following regulations:

6.3.2 Decontamination

Personal protective equipment shall be chosen and worn in conformance with 29 CFR 1926.95, 1926.96, and 1926.102. The eye protection should be goggle type with side shields, and vented. In the event of leakage, protective gloves should be worn at all times during the handling of any potential

PCB-containing materials.

Workers shall first remove disposable protective clothing and deposit in waste receptacles before using the hand-washing facilities. Before removing their respirators and entering the clean change area, employees shall wash hands, forearms, face, neck, and exposed skin.

All workers handling known or suspect PCB-containing materials will have access to washing facilities equipped with soap, warm water and towels. Employees shall wash hands (up to forearms), neck and face prior to breaks (including meal breaks) and prior to leaving the work site at the end of the day. Employees will not be permitted to smoke, eat or apply cosmetics nor any other type of “hand to mouth activity” during work associated with PCBs prior to washing hands, face and neck.

Contractor shall provide storage facilities in the clean change area for employees' street clothes, cleaned reusable personal protective equipment (e.g., goggles, respirators), and personal items.

Also, provide an adequate supply of clean disposable protective work clothing, replacement filters for respirators, and disposable towels.

Contractor shall provide the hand washing facilities with a suitable supply of clean potable water to permit each employee to wash hair, hands, forearms, face, and neck. Also, provide clean disposable towels and labeled waste bags and containers for depositing used disposable protective work clothing and towels.

7.0 WASTE DISPOSAL

7.1 Asbestos

Friable asbestos-containing waste (if generated) shall be managed for disposal as a California hazardous waste. Hazardous wastes shall be immediately removed from the property by a waste hauler with required licenses from state and local authorities with jurisdiction.

Asbestos waste shall be double-contained by: 1) wrapping components in two layers of 6-mil polyethylene sheeting, 2) wrapping or bagging waste in 6-mil polyethylene bags and placing in containers lined with 6-mil polyethylene sheeting, or 3) placing in 6-mil polyethylene bags

(double-bagged). Containerized asbestos-containing waste shall be transported out of the regulated area through the equipment area. Asbestos-containing waste containers shall be properly labeled in accordance with Title 8, CCR, §1529(k)(8).

Nonfriable asbestos-containing waste is nonhazardous in California.

Geocon Project No. A8575-06-21 -15- July 28, 2017

When drums, bags, or wrapped components have been removed from the work area, they shall be loaded into an enclosed or covered container for transport. If large dumpsters are used for asbestos waste disposal, they shall have doors or tops that can be closed and locked to prevent vandalism or other disturbance of asbestos debris. Bags of asbestos-containing waste shall be placed, not thrown, into these containers to avoid splitting.

Disposal must occur at an authorized facility in accordance with the regulatory requirements of

NESHAP and applicable State and local regulations. The Contractor shall obtain permits required for transport and disposal of hazardous waste and asbestos-contaminated waste, and provide copies of all waste disposal documentation to the DGS or their designated representative.

7.2 Lead

The Contractor is responsible for providing waste receptacles required for disposal. The Contractor shall locate disposal facilities that will accept LCP debris/waste materials removed from the Site. Solid wastes that are not classified as hazardous shall be disposed of in a State-approved landfill. Hazardous wastes shall be immediately removed from the property by a waste hauler with required licenses from state and local authorities with jurisdiction. The Contractor shall obtain permits required for transport and disposal of lead-containing/contaminated debris/waste, and provide copies of waste characterization/waste disposal documentation to the DGS or their designated representative.

The Contractor shall follow all Federal and State regulations for handling, characterizing, containerizing, and disposing of lead-containing/contaminated waste materials per the requirements of Title 22, CCR and the Resource Conservation and Recovery Act (RCRA).

Debris is to be treated as hazardous lead waste if results of laboratory analysis indicate a lead concentration at or above any one of the following criteria for lead content:

Total Threshold Limit Concentration (TTLC) - 1,000 mg/kg;

Soluble Threshold Limit Concentration (STLC) - 5.0 mg/l; or

Toxicity Characteristic Leaching Procedure (TCLP) - 5.0 mg/l.

For a waste to be managed as non-hazardous, the landfill may also require that the waste pass the acute fish toxicity test in of Title 22, CCR, §66261.24(a)(b).

Geocon Project No. A8575-06-21 -16- July 28, 2017

7.3 Universal Waste

The Contractor is responsible for providing waste receptacles required for universal waste recycling transportation or disposal. The Contractor shall locate recycling contractors and facilities that will recover/recycle air conditioner refrigerant and accept fluorescent light tubes removed from the Site.

The Contractor shall locate disposal facilities that will accept mercury (broken light tubes) and

PCB-containing debris/waste materials removed from the Site. Hazardous wastes shall be immediately removed from the Site by a waste hauler with all required licenses from State and local authorities with jurisdiction. The Contractor shall obtain permits required for transport and recycling/disposal of universal waste and hazardous waste, and provide copies of waste characterization/waste disposal documentation to the DGS or their designated representative.

The Contractor shall follow Federal and State regulations for handling, characterizing, containerizing, and disposing of broken fluorescent light tubes, PCB-containing light ballasts, and associated contaminated debris waste materials per the requirements of Title 22, CCR, RCRA, and TSCA.

Spent fluorescent light tube shall be considered hazardous wastes and labeled as such for temporary onsite storage, transportation, and disposal or recycling. Fluorescent light tubes shall be disposed of as a hazardous mercury waste at a permitted land disposal facility or recycled.

Known or suspect PCB-containing materials must meet the packaging requirements of 49 CFR Parts

171-180 (40 CFR 761.60). When packaging PCBs, the interstitial space in the container must be filled with sufficient absorbent materials to absorb any liquid PCBs remaining in the components. Fluorescent light ballasts containing PCBs in their potting material must be disposed of in a TSCA approved disposal facility as a bulk product waste. Any discharges or spills shall be cleaned up and reported. Known or suspect PCB-containing ballasts shall be managed, labeled, and disposed of as California Hazardous

Waste. A California hazardous waste manifest shall be prepared by the Contractor and used for each shipment of PCB ballasts and PCB-contaminated items or materials. Fluorescent light ballasts labeled as

“No PCB's” may be disposed of as non-hazardous construction waste.
