The contractor shall establish work area boundaries that will:
- Establish a decontamination zone to allow only authorized access to the work areas including personnel decontamination area and staging area.
- Ensure that unauthorized people do not enter the work area.
- Protect people in the vicinity of the work area from potential dangers that may exist in the work areas.
- Ensure contaminants are contained within the work areas.
The contractor should notify the local emergency medical services, police and fire departments in writing of the type and scope of work being performed and request that these departments make an inspection prior to beginning the work.
Universal and hazardous materials and waste may be accumulated and temporarily stored on UNC property, but storage should not exceed 30 days except for extremely hazardous materials, for which arrangements should be made to remove the material from the premises as soon as is practicable. The contractor will provide locked storage for hazardous materials and waste with a clearly marked and labeled section specifically devoted to hazardous waste. Satellite Accumulation Rules should be followed until a total of 55 gallons of waste is accumulated. Once that threshold has been crossed, less than 90 day storage requirements must be implemented. The contractor will clearly identify the storage areas with proper signage and secure the area.
The hazardous and universal waste accumulation area will be pre-approved by UNC and the designer before wastes are stored there. The areas will be open for inspection by UNC Environment, Health and Safety (UNC EHS) or designer upon request. Hazardous waste accumulation area shall be locked when not in use.
The contractor is responsible for keeping the staging area secure. Waste materials will be protected from the weather and stored off the ground. The contractor will complete inspections of the waste storage area on a weekly basis and complete a daily inspection log. The contractor will keep the inspection forms in a project logbook on-site and provide copies to UNC EHS and/or the designer upon request. The contractor shall confirm that containers are secure and not leaking, and wastes are segregated into compatible groups and is properly labeled.
The contractor shall maintain an adequate quantity of spill response supplies to contain, at a minimum, 115% of accumulated waste. If a spill or leak is detected, the contractor shall immediately contact UNC-EHS. The spill or leak should be contained as soon as it is safe to contain. The contractor should clean the spilled material and contain it according to federal, state and local regulations and guidelines. UNC-EHS will assist the contractor in completing the required paperwork, including reporting and regulatory agency notification, as required.
The contractor shall provide temporary connection to existing building utilities or provide temporary facilities as required herein or as necessary to carry out the work.
The contractor shall employ qualified tradesmen for installation of temporary services and facilities. The contractor shall work with UNC to locate, modify and/or extend temporary services and facilities where they will serve the project adequately and result in minimum interference with the performance of the work.
The contractor shall supply hot and cold water to the decontamination units. Hot water shall be supplied at a minimum temperature of 100 degrees Fahrenheit.
After completion of use, connections and fittings initially installed by the contractor shall be removed by the contractor without damage or alteration to existing water piping and equipment.
Refer to the UNC Design and Construction Guidelines for further information including Chapter V – Technical Design and Performance Standards – Division 15, Mechanical Systems.
The contractor shall lock and tag out electrical and Heating, Ventilation, and Air Conditioning (HVAC) equipment in the work area.

The contractor is responsible for connection of power panels and providing temporary electrical services to the work areas.
The contractor shall provide temporary facilities as required herein or as necessary to carry out the work. The contractor shall contact UNC Electric Systems for the location of the temporary service equipment, the appropriate size of any CT cabinets (if required), and associated costs for the service. Temporary service is generally provided just inside the construction site fence at an agreed point of delivery as approved by UNC Electric Systems.
Standard temporary service is typically overhead but may be installed underground depending on the construction site. UNC Electric Systems’ preferred temporary service is single-phase 120/240 volt furnished from an overhead transformer. Overhead or underground three-phase 120/208 volt, 120/240 volt and 480 volt services can be made available. UNC discourages the use of single-phase 120/240 volt service due to the associated cost.
Temporary services of 200 amperes and under are metered with self contained meters and require a standard meter base supplied by UNC Electric Systems. Temporary services over 200 amperes require current transformers for metering and require a CT cabinet supplied by the contractor.
The contractor is responsible for coordinating and acquiring all local inspections and filing an application for services with the Energy Services Business Office. The filing date must allow adequate time for UNC Electric Systems to provide the desired service.
The contractor shall provide a structure sufficient in strength and height to accept the appropriate overhead or underground supply conductors and to comply with appropriate local and NEC codes for height, voltage, clearance and utilization of power.
The contractor shall employ qualified tradesmen for installation of temporary services and facilities. The contractor shall locate, modify and extend temporary services and facilities where they will serve the project adequately and result in minimum interference with the performance of the work.
Ground Fault Protection: The contractor shall provide receptacle outlets equipped with ground fault circuit interrupters (GFCI), reset button and pilot light, for plug-in connection of power tools and equipment. All GFCIs shall be located outside the containment area. All powered equipment shall be connected to a GFCI.
The contractor shall provide a weatherproof, grounded temporary electric power service and distribution system of sufficient size, capacity and power characteristics to accommodate performance of work during the construction period.
The contractor shall install temporary lighting adequate to provide sufficient illumination for safe work and traffic conditions in every area of work. The contractor will not be allowed to utilize the existing lighting at the site during abatement of asbestos-containing materials. All light fixtures shall be cleaned and removed under the containment or wrapped with two layers of six mil polyethylene sheeting. Maintain a level of at least 75 foot candles in all construction areas. During the final visual inspection, the temporary lighting shall be maintained at level of at least 150 candle foot. Any deviations in the lighting requirements must be approved by UNC EHS and/or the Project Designer. If adequate lighting is not provided during the work process, during visual inspection by UNC EHS, project designer or IH firm, in and/or during air monitoring, the project will be shut down at the contractor’s expense until lighting is provided. There will be no additional time allotted to the contractor for the project in the event these circumstances arise. Reference OSHA 29 CFR 1926.56(b).
The contractor shall provide services of an electrician, on a standby basis, to service electrical needs during the abatement process.
The contractor shall provide additional power service and distribution service, consisting of individual, dedicated 15 amp 120 volt circuits to electrical drops with receptacle outlets
equipped with ground fault circuit interrupt protection, color coded for the exclusive use of the industrial hygiene firm. A minimum of 5 drops per work area is required. Refer to the UNC Design and Construction Guidelines for further information including Chapter V – Technical Design and Performance Standards – Division 16, Electrical – Section 16050 – General and Section 16441 – Service and Distribution.
The contractor is responsible for maintaining secure entry/exit locations at the facility while work is being completed.
The contractor shall maintain a logbook in the clean room area of the decontamination system. Anyone who enters the regulated area must record name, affiliation, time in, and time out for each entry.
Access to the regulated area shall be through a single decontamination system. Other means of access (doors, windows, hallways, etc.) shall be blocked or locked so as to prevent entry to or exit from the regulated area. The only exceptions to this rule are the waste pass-out air lock that shall be sealed except during the removal of containerized waste from the regulated area, and emergency exits in case of fire or accident. Emergency exits shall not be locked from the inside; however, they shall be sealed with polyethylene sheeting and tape.
- The Hazardous Materials Management Program maintains UNC’s chemical inventory system and hazardous materials use permits. Chemical inventory reports can be generated and sorted by location and chemical-specific parameters such as hazard class, toxicity and physical state. This information may used by the contractor to evaluate recent potential sources of contamination within a lab.
- Hazardous waste generated on campus is processed through the UNC-EHS’ Chemical Waste Program. A representative of UNC-EHS must observe waste sampling, review all testing data and waste determinations and must sign all manifests. The waste shall be accepted, transported and disposed by one of the pre-qualified waste disposal contractors
listed in Section 1, 1.14 – Hazardous and Universal Waste Disposal. The contractor is responsible for fees associated with transportation and disposal of hazardous and universal waste materials.
- The contractor is responsible for certifying, by documentation, items which are decontaminated and disposed are clean and free of hazardous materials. If such decontamination is completed to remove only a certain amount of hazardous materials to a level appropriate for a specific disposal option, this must also be documented by a proper waste determination.
- The UNC-EHS also tracks the use of radioactive materials and equipment on campus. A health physicist is assigned to every research project that uses isotopes and assists the
researcher in moving materials between locations. The health physicist also coordinates terminal radiation surveys.
- The Biosafety Program tracks the use of biohazardous materials and assists the professors with relocation of such materials.
- Radioactive materials currently stored in the building will be relocated by UNC-EHS prior to the contractor beginning work. UNC-EHS will complete testing to confirm a radiation hazard does not exist in the known storage locations of radioactive material. The contractor shall utilize a radiation meter during the completion of the work to protect workers from potential radioactive materials that may be discovered during completion of the work. UNC-EHS must be notified immediately of any positive findings.
Decontamination of Potential Biological/Pathogenic Materials (optional)
The contractor will disinfect all biosafety laboratory suites and biosafety cabinets (e.g., biosafety cabinet work surfaces, etc.) wiping them thoroughly with a 10% bleach solution. Arrangements should be made for more rigorous disinfecting procedures for Biosafety Level II and III suites involving paraformaldehyde vapor procedures or other equivalent methods pre-approved by the UNC-EHS Biological Safety Office.
A mercury survey will be performed by UNC, the results of which will be provided to the contractor and will be the basis for determining which labs and areas require decontamination.
This initial survey will indicate areas of greater probability of finding mercury, but all areas must be tested during the removal of plumbing and case work. Although this survey will serve as the initial scoping document for mercury abatement activities, the contractor must be aware that during the performance of the contract, particularly during demolition activities, other areas of mercury contamination may be identified, which will be the responsibility of the contractor to properly decontaminate.
This section covers the demolition, use, handling, storage, transport, accumulation, and disposal of mercury spills and mercury-contaminated building and laboratory materials. The contractor should be aware that elemental mercury, and its compounds- e.g., organic and inorganic mercuric salts, are inhalation and contact toxins that require special handling and disposal precautions. Mercury compounds are regulated by numerous statutes and regulations, particularly regarding workplace exposure avoidance and prevention of releases to the environment.
The contractor is advised that mercury spills may contaminate asbestos-containing building materials that may be removed by the contractor. The presence of mercury above hazardous waste action levels on asbestos-containing materials requires that the material be managed as a hazardous waste. The contractor is responsible for properly accumulating, storing, and disposing of mercury-characteristic and other hazardous wastes at an EPA permitted and UNC approved Treatment, Storage, and Disposal Facility (TSDF). The contractor is required to subcontract an approved UNC-Chapel Hill hazardous waste disposal contractor for disposal of hazardous waste generated under this contract. The contractor shall notify UNC and designer when UNC owned hazardous materials, not specifically identified in this contract, are discovered. Methodologies for removal and/or decontamination of the newly identified hazards will be presented to the owner and designer for approval prior to the initiation of mercury abatement activities.
Personal protective equipment for workers should be clearly specified in the site specific health and safety plan for the project. A minimum of Level C protection is recommended. Most of the protective measures detailed in Section 6.00 of the Asbestos Abatement Specification have general application to decontamination of mercury spills and demolition activities in the presence of mercury. Exceptions are the use of respirators fitted with mercury vapor cartridges and chemically impermeable gloves (nitrile or rubber) to prevent mercury compounds from contacting the skin.
Removal of mercury-containing intrinsic items
Manufactured or intrinsic items containing elemental mercury will be identified by the inspector and reconfirmed and removed by the contractor. Examples of intrinsic items containing mercury include: manometers and pressure gauges (e.g., Stokes McCleod gages), thermometers (laboratory and duct insertion), pumps, switches (e.g., MERCOID switches, etc.), thermostats, and fluorescent tubes (see Section 13.0A). The contractor will segregate these items from other mercury-containing waste and manage them as hazardous and/or universal after they are removed. The contractor will arrange to have intrinsic items shipped to a recycler for recovery of mercury by retort. All shipping paperwork must be signed by an UNC-EHS representative.
UNC “Controlled Materials” are defined as any material that poses a human health threat or damage to the environment. Disposal options should be thoroughly investigated for these materials and may involve recycling or reuse or disposal. Irresponsible discharges to the environment or improperly managing waste should be avoided. It is imperative that the use, handling, storage, transportation, and disposal of hazardous and recyclable materials and waste from UNC facilities and the UNC campus are consistently managed following the guidelines outlined in federal, state, local, and UNC regulations. This ensures the safety of UNC personnel and visitors and averts liability or penalties to UNC from the reckless or improper disposal or management of waste generated during the performance of the contract or during transport off campus.
The contractor shall have a mercury spill kit, mercury vacuum or other appropriate equipment on-site in the immediate location of work activities. The contractor shall clean visible mercury discovered or accidentally spilled while completing work. If mercury is detected visually or with mercury vapor detection equipment, the contractor shall immediately notify UNC-EHS and initiate cleanup activities.
Mercury action levels and regulatory exposure limits
- Air Survey Action Level (ASAL): 250 ng/m3 (0.000250 mg/m3)
- the concentration of mercury in the initial air survey above which action must be initiated to both identify the source and to remove or decontaminate it. Areas below the ASAL during the initial survey must also be tested during the removal of plumbing and case work. The ASAL is established at 1/100 the TLV (defined below) to provide a substantial margin of protection for building occupants and workers and to ensure that all sources of mercury are discovered. Please note that the ASAL is 4 times less than the concentration of mercury vapor allowed after decontamination is attempted to offset the limited ability to detect less volatile mercury compounds (i.e., inorganic mercuric salts) that may be present at concentrations also requiring decontamination. The contractor should include methodologies for removing these inorganic compounds in proposed decontamination procedures.
- OSHA Permissible Exposure Limit (PEL) for mercury: 100,000 ng/m3 (0.1 mg/m3)
- Maximum allowed worker exposure over an 8-hour time weighted average.
- NIOSH 8-Hour Time Weighted Average (TWA): 50,000 ng/m3 (0.05 mg/m3)
- Maximum recommended worker exposure over an 8-hour period.
- OSHA Permissible Exposure Limit for Methylmercury- 10,000 ng/m3 (0.01 mg/m3)
- Maximum allowed worker exposure to this toxic organomercury over a 8-hour TWA. Methymercury is the metabolic product of mercury and is typically accumulated in bacterial sludge in wet sink traps.
- Threshold Limit Value (TLV): 25,000 ng/m3 (0.025 mg/m3
- Established by the American Conference of Governmental Industrial Hygienists (ACGIH) this is the timeweighted average concentration of mercury in the air for a normal 8-hour work day and 40-hour work week. Workers may repeatedly be exposed to this concentration without experiencing adverse health effects.
- Agency for Toxic Substances & Disease Registry (ATSDR) Indoor Air Quality: 1,000 ng/m3 [0.001 mg/m3]
- This is the recently established maximum concentration for residential indoor air quality published by an agency of the Center for Disease Control and Prevention (CDC).
- Post Decontamination Air Clearance Level (PDCL): 1,000 ng/m3 (0.001 mg/m3)
- This is the concentration of mercury vapor at the surface of a item or area, which has been decontaminated, below which the item or surface requires no further decontamination and, therefore may be disposed as a non-regulated solid waste for recycling or reuse.
- Toxicity Characteristic Leaching Procedure (TCLP): 0.2 mg/L
- Mercury concentration in a TCLP extract (EPA Method SW 1311) of a solid waste equal to or above which the material must be managed as a mercury-characteristic hazardous waste.
- Total Mercury Concentration Clearance Level: 4.0 mg/kg [4 ppm]
- the total concentration of mercury in a digest of a solid waste equal to or above which the material must be managed as a hazardous waste. The level was established to afford an estimate of the TCLP extraction efficiency and is 20 times the TCLP action level. Typically this test is run in lieu of TCLP, when limited sample is available.
- North Carolina Wastewater Discharge Limit: 0.0002 µg/L
- The concentration of mercury in wastewater below which it may be safely and compliantly discharged to the sewer. Wastewater with concentrations equal to or greater than 0.0002 µg/L will be disposed of as hazardous. It may not be discharged to storm drains, the municipal sewer, sanitary drains in the building, or dumpsters, nor may it be poured on the ground or directly released to the environment in an uncontrolled fashion. Demonstrated decontamination procedures have not generated significant quantities of hazardous wastewater, however, if large quantities are produced, the contractor will investigate wastewater treatment options to remove or extract specific contaminants preventing it from being discharged to the sewer.
- Reportable Spill Quantity
- EPA’s reportable spill quantity for mercury is approximately 33.6 milliliters (approximately 2-3 tablespoons of liquid). Any quantity equal to or greater than this must be reported to the EPA and state authorities as an uncontrolled release of mercury to the environment. Reporting of any spill to the EPA and state authorities must be coordinated through UNC-EHS. Notify UNC-EHS as soon as possible after a spill has occurred. Reported releases subsequently require formal planning procedures or remedial site investigation and formal clean-up activities, which includes removal, remediation, and/or disposal of contaminated material, i.e. soil, etc.
The contractor will comply with all regulations and conditions of UNC permits and licenses applicable to the project. Included are wastewater discharge permits and satellite accumulation requirements for hazardous waste, etc.
The contractor assumes responsibility and liability for compliance with all applicable regulations especially those affecting the health and safety of contractor employees, subcontractors, and all others at UNC during the performance of the work. This responsibility includes the protection of UNC employees and visitors located near the worksite. Prevention of damage to UNC property, supplies, and equipment from accidents, improper storage or misuse of hazardous materials shall also be avoided.
Hazardous materials and waste may be accumulated and temporarily stored on UNC property per the provision of UNC’s hazardous waste permit, but should not exceed 30 days, except for extremely hazardous materials, for which arrangements should be made to remove the material for the premises as soon as is practicable. The following conditions should be met to ensure that hazardous substances are properly managed:
- Hazardous waste containers should be in good condition, compatible with the material being stored in it, properly labeled at all times, and free of leaks.
- Adequate secondary containment should be provided for those wastes where accidental discharges or leaks could cause an environmental release.
- Hazardous waste accumulation areas will be pre-approved by the owner and designer before wastes are stored there. The areas will be open for inspection by the owner or designer upon request. Hazardous waste accumulation areas shall also be inspected at least daily by the contractor or its environmental oversight subcontractor and shall be locked when not in use. Wastes in containers that are leaking will be immediately transferred to a reliable container and any spilled material properly cleaned up.
The contractor should coordinate waste disposals with one or more of the UNC approved vendors listed below (as listed on the UNC website). The contractor is responsible for the disposal fees of hazardous and universal waste disposal.
Do not ship any Hazardous or Universal Wastes without EHS notification and approval. EHS must be notified to ensure that the proper paperwork, with the correct EPA ID number, addresses, and emergency contact information is used. An EHS representative MUST sign all paperwork for recycling or disposal shipments Universal or Hazardous Waste, including Bulbs.

The contractor is required to submit a Draft Solid Waste Management Plan fourteen days prior to beginning work activities. The draft should be submitted simultaneously to the designer and the UNC Office of Waste Reduction and Recycling (OWRR) in order to expedite plan review. Once OWRR has communicated requested changes, the contractor has five business days to submit a Final Solid Waste Management Plan (SWMP) (UNC Specification 01505). Any deviance from the final SWMP must be approved by OWRR. In accordance with Specification 01505, each month the contractor must submit documentation (weight tickets, manifests, etc.) of the disposal, recycling, re-use, and salvage of all materials and a summary with each Payment Application. Failure to do so may delay payment. See UNC Design and Construction Guidelines for additional information concerning recycling of non-hazardous materials.
- Cover Sheet entitled “Project Testing Summary Report,” stating the project name, contractor project number and UNC project number
- Test Completed
- Location of Test Including Room Name and Number
- Test Results
- Date Samples Sent to Laboratory (if applicable)
- Date Sample Results Were Received From Laboratory (if applicable)
- Copy of the Laboratory Results (if applicable)
The contractor shall provide 3 typewritten copies of each report to UNC-EHS and the designer within one week of the test date.
At the conclusion of each phase of environmental demolition, the following individuals will walk the site together to review the completed work and check for deficiencies:
- Environmental Abatement designer
- Environmental demolition contractor
- Construction manager
- EHS representative
- General contractor/CM responsible for subsequent renovation work
The architect and the environmental abatement designer will attest in writing that all hazardous material has been abated or secured according to the specifications and no remaining hazardous material will be disturbed in this space by subsequent construction activity in this space. If all hazmat has not been addressed, the architect will prepare a punch list of deficiencies to be corrected at the contractor’s expense. While fixing the punch list items, the contractor is expected to use the required protective measures necessary to complete the work as outlined by the abatement designer.
If the construction manager or the EHS representative disagrees with the clearance assessment of the architect and consultant, additional testing may be required. If this testing reveals residual contamination, the cost of this testing and additional testing shall be born by the architect and the consultant. Additional abatement expense shall be absorbed by the environmental demolition contractor.
The next phase of construction can begin in the designated work space after all parties agree on the clearance and the architect and consultant sign a document to release the space.
- Monitoring the contractor’s work involving the identification and decontamination of mercury for compliance with the federal, state and local regulations and the provisions of this specification. Included shall be the oversight of activities for properly characterizing, handling, storing, and transporting wastes.
- Monitoring air quality of the worksite and contiguous occupied spaces of the building for hazardous vapors, fire and explosion hazards, fumes, dust, aerosols, and odors, etc. The EHSM will assist in the identification and resolution of complaints from contractors, UNC employees and visitors regarding same.
- Provide the Construction Manager and his technical authorities with documentation of monitoring and test results impacting the progress of the work and the quality of the workplace environment, as well as test results intended for hazardous waste characterization.
- The EHSM will be physically present for the following activities/phases of the project related to mercury (similar specifications may be required for other hazardous materials besides mercury and asbestos):
- Air Monitoring during mercury abatement procedures including surface decontamination and sanitary pipe removal described below.
- Mercury testing and surveying to delineate the extent of previously identified mercury spills during the initial survey and/or newly discovered mercury spills that are uncovered during the demolition and removal of laboratory casework, etc. Testing must be performed during the dismantling and removal of laboratory plumbing and casework off floor at all times.
- Characterization of mercury-containing hazardous wastes using the project surface vapor concentrations outlined in Mercury Safety, specifically those in that exceed the PDCL.
- Mercury exposure monitoring involving the evaluation of the breathing zone air during all decontamination and demolition activities.
- Air-monitoring and sampling during all other work activities, i.e. nuisance dust sampling, fume hood sampling, etc.
