Scope of Work

Midpeninsula Regional Open Space District will be performing a demolition project of various buildings at their Estrada Property. To meet requirements of the NESHAP regulation, the removal of asbestos-containing materials is required to be completed prior to demolition. The contractor awarded the project shall ensure that all applicable aspects of these specifications, as well as Federal, State, and local regulations are followed by either their own firm, or their sub-contractors as applicable for the site work to be completed.

Project Requirements

The Contractor performing work must be registered with the Division of Occupational Safety and Health (DOSH) as an asbestos abatement contractor. Contractor must hold the C-22 asbestos abatement license.

The site assessment identified propane tanks and liquid acid car batteries, both classified as hazardous materials under California regulations. Propane tanks, containing liquefied petroleum gas (LP-Gas), are subject to stringent storage and handling requirements to prevent leaks and explosions. California Code of Regulations, Title 8, Section 471 mandates that LP-Gas be odorized to detectable levels before transportation or delivery to ensure safety. Similarly, liquid acid car batteries, primarily composed of sulfuric acid and lead, are considered hazardous waste when discarded. The Department of Toxic Substances Control (DTSC) requires that spent lead-acid batteries be recycled or disposed of following specific guidelines to mitigate environmental and health risks. Proper management of these materials includes compliance with handling and disposal protocols as outlined in California's hazardous waste regulations.

SUBMITTAL REQUIREMENTS

A copy of the contractor’s prestart submittal shall be provided to the onsite project monitor and shall include the items listed in the attached Asbestos General Requirements at Sections 2.2, 2.31a, 2.31b, 2.31c, and 2.5.

Contractor will be responsible for providing water and electricity at work areas for this project. Neither will be available onsite.

Pre-Cleaning

No pre-cleaning of asbestos-containing materials is required for this project.

Safety / Security

The contractor is responsible for the safety of all employees and following all applicable regulations, namely Cal/OSHA. A tailgate safety meeting shall be held on the first day of the project by the crew supervisor to discuss all safety hazards on the project. A sheet signed by all attendees and the presenter with the topics discussed shall be provided to the FACS onsite project manager.

Safety meetings shall be held at least weekly or in the event that job hazards change on the project or if an accident occurs on the project.

Contractor is responsible for the security of their equipment onsite and work area.

Occupancy

The contractor will have sole access to the work area.

Personal Air Monitoring

The contractor is responsible for the collection of personal air samples during the abatement of asbestos-containing materials in accordance with Cal/OSHA requirements.

11. Once a clearance visual inspection has been passed by the FACS onsite project manager, the contractor shall remove all containment barriers and regulated area.

Waste Disposal

Contractor is responsible for providing a waste receptacle on site for the storage of all asbestos-containing materials. Waste bins to remain onsite past a work shift must be covered/enclosed with a hard-top lid and lockable to keep waste secured. The waste bins must arrive onsite clean of debris.

Waste bins shall be load-worthy and the contractor is responsible for any costs associated with load loss.

Plywood or similar material shall be installed below the feet / casters of the waste bin to prevent damage to ground surfaces.

The waste bin shall be lined with one layer of 6-mil poly prior to loading of waste. This liner does not count as one layer of packaging for waste. All waste must be double-bagged in 6-mil poly waste bags or “burrito-wrapped” in two separate layers of 6-mil poly. Waste bags shall be sealed in a “goose neck” fashion and “burrito-wraps” shall have staggered tape seals to create a leak-tight container. All waste shall be wet inside waste bags but may not contain “loose” water. Air within waste bags shall be evacuated using a HEPA-vacuum when sealing.

All waste packages shall be labeled in accordance with Cal/OSHA and DTSC requirements as necessary for waste being disposed. Hazardous (regulated) and non-hazardous asbestos waste materials may not be mixed within the same waste container / bin. Contractor shall provide either drums or boxes to segregate wastes in the event all waste will be hauled in the same waste hauler.

All waste must be manifested, even if considered to be non-hazardous. Contractor shall provide at least 24-hour notice of waste manifest needing to be signed to allow coordination with District’s personnel for signatures.

Clearance

At the conclusion of abatement, the crew supervisor shall perform own visual inspection of the regulated work area to ensure all materials have been abated and the work area is clean of all dust and debris. Once they pass their own visual inspection, they may request a visual inspection from the FACS onsite project manager. To pass a final visual inspection, all materials need to be abated, the work area must be dry, and no dust or debris may be present. Once FACS onsite project manager passes the final visual inspection, contractor shall fold poly drop sheets in on itself and remove regulated area signage.

Encapsulant, Bridging/Penetrating - A liquid material which can be applied to asbestos-containing

Asbestos Gen. Requirements - Page 4 of 54 material to control the possible release of asbestos fibers from a material either by creating a membrane over the surface (bridging encapsulant) or by penetrating into the material and binding its components together (penetrating encapsulant).

Encapsulant, Lock-down - A liquid product designed to mist the air within a contained area after the containment has passed visual clearance by the HMS, Inc. Project Manager. Lock-down encapsulant is designed to bind asbestos fibers together and to create a tacky surface causing non-visible asbestos fibers, settling out of the air, to adhere to containment poly.

Equipment Decontamination Enclosure System - That portion of a decontamination enclosure system designed for controlled transfer of materials and equipment into or out of the work area, consisting of a clean room, washroom and holding area.

Equipment Room - A contaminated area or room which is part of the worker/equipment decontamination enclosure system with provisions for storage of contaminated clothing and equipment.

Exterior of Containment HEPA Filtered Pressure Differential Unit - An air-purifying unit positioned outside, rather than inside the regulated work area. The face, or filter portion of the unit is integrated within the work area, and the remainder of the unit (housing, wheels, rivets, control panel, etc.) is located outside of the work area. This allows filters on the air intake to be changed from within the regulated area but access to the machine itself is available to those outside the area. Pressure differential units which pass

DOP testing across the HEPA filter, but fail at rivets, control panels, wheels, etc. may be used in this fashion as long as the failure point of the unit can remain on the exterior of containment while the face of the unit and filters are inside containment.

(typically constructed of 6 mil transparent polyethylene or polyvinylchloride plastic), two inward projecting long sleeves, an internal tool pouch, and an attached, labeled receptacle for asbestos waste. The glovebag is constructed and installed in such a manner that it surrounds the object or material to be removed and contains all asbestos fibers released during the process. Glovebags must meet the specification requirements for glovebags as listed in 8 CCR 1529. All workers who are permitted to use the glovebag technique must be highly trained, experienced and skilled in this method. All techniques and procedures employed by the contractor shall be approved by the HMS, Inc. Project Manager.
