Hazardous Building Materials Survey — Building 3041 Hangar Renovation

December 1, 2012 1 Helix Design Group, Inc.

Survey Summary

On October 31 and November 1, 2012, Jon A. Havelock, CSP, CHMM, and Mike Webb of Med-Tox Northwest (MTNW) conducted a renovation specific hazardous building materials (HBM) survey of Building 3041 located at Joint Base Lewis-McChord (JBLM), Washington.

The survey included asbestos, lead-based paint (LBP), and other potential HBM such as chlorofluro carbons (CFC), polychlorinated biphenyl (PCB) light ballasts, and mercury-containing fluorescent tubes and/or thermostats that will be impacted by replacement or repair of the existing fire suppression system. This survey was performed for the following renovation items:

The overall and prioritized project scope was reviewed. Per the Statement of Work the scope will consist of the following:

• The new exterior building envelope Scope of Work will consist of the following: the demolition the existing roof and wall system materials to the existing framingIstructure. Provide new- furring/framing (if required), insulation, sheathing (if required), weather barrier, metal roofIwall panels, new windows and doors (inclusive of renovated or new hangar doors).

• The building's fire suppression system(s) Scope of Work is as follows: the existing wet fire suppression system at the non-hangar (2-story wing) areas will be demolished and replaced (the risers shall remain). The existing deluge system at the hangar bays will remain but any/all deficiencies will be addressed.

• The building renovation will address the user's interior space planning upgrades and new interior finishes throughout the interior of the building.

This work is inclusive of the complete renovation of the existing toiletIshower rooms.

• The buildings heating, ventilation, and air conditioning (HVAC) & plumbing systems will be addressed as follows: the existing steam heating system will be demolished and replaced with a hot water system in the non-hangar areas A gas fired radiant heat system will be provided at the hangar bays. The existing above grade plumbing pipe will be demolished and replaced with new. The below grade waste piping shall remain providing it is sound and functioning properly.

• The building's communications system and light fixtures: the buildings communications system will be reviewed and brought up to JBLM standard as required. All light fixtures shall be replaced

• The building electrical system up-grade: the condition of the existing electrical systems will be evaluated; (wiring, distribution panels, devices, etc.) and replacedIupgraded as necessary to meet JBLM standards.

December 1, 2012 2 Helix Design Group, Inc.

Specific user requested renovations to the existing building spaces will also be performed.

This survey consisted of a visual inspection, touching of suspect materials, and sample collection with analysis. As-built drawings were available and reviewed as part of this survey report; additionally, Prezant Associates, Inc. (Prezant), performed a limited asbestos survey of the building in 1993; see Appendix A. Copies of the Asbestos Hazard Emergency Response Act (AHERA) building inspector certificates and State of Washington Department of Commerce (WDOC) lead-based paint accreditation are included in Appendix B.

Building Information General and Structural Building 3041 is an aircraft hangar with a 27,386 square foot (SF) footprint that was constructed in 1964. On both sides of the hangar are support and office wings with a lower roof line and are two stories.

Construction is slab-on-grade concrete with a metal framework and exterior insulated metal panels. Metal panels consist of the exterior corrugated metal siding with a 1-inch layer of fiberglass and then a sheet metal finish on the building interior. No glues or suspect asbestos papers were observed inside the system in the limited areas where the entire component was visible.

Roof systems are sloped with rigid insulation and built-up roofing systems.

Personnel and small equipment doors throughout the building are metal, some newly installed and others likely original. Large fire doors are constructed with wood internal framing and metal skin; these were drilled and determined non-asbestos fire doors.

Hangar doors are constructed out of metal and have fiberglass insulation on the interior.

Windows are aluminum framed and originally without glazing/putty and for the most part, remain as originally installed. There are, however, repair windows installed with glazing/putty, which is located on the building exterior.

Photographic documentation of the building and its major systems described herein are provided in Appendix C.

Heating/Mechanical/Plumbing System Heating in the offices and maintenance rooms on the side of the hangar consists of radiant fin tubing mounted on the walls. There are also gas fired overhead radiant heaters in the hangar, but these are newer systems.

The boiler room has a newer boiler which supplies radiant hot water to heating systems throughout the building. Much of the boiler room piping is new with fiberglass insulation

December 1, 2012 3 Helix Design Group, Inc.

systems; however, a small amount of older fiberglass insulation with asbestos insulating cement fittings remain.

Prezant identified asbestos-containing pipe fitting insulation in 1993; much of this remains in the building.

Architectural Finishes Ceilings Ceilings throughout the building primarily do not have architectural finishes except for paint coatings; however, there are a few offices with new acoustical ceiling tiles (ACT).

Walls The hangar is constructed with steel framing and insulation panels on the outer walls.

Exterior finishes consist of corrugated metal panels over the insulation panels.

According to as-built drawings, the insulation was an asbestos-faced insulation product.

MTNW inspected for the asbestos facing, but none was observed. There are also two concrete demising walls that run north and south and separate the hangar area from the support shops and offices.

Stairwell walls on the north and south sides of the building are constructed out of cement masonry unit (CMU); paint schemes are the same throughout. First and second floor room configurations and restrooms are mainly divided with CMU walls.

Observation of penetrations in CMU walls throughout the building did not reveal evidence of vermiculite insulation; however, due to occupancy, destructive investigation was not performed.

There are a few gypsum wall board (GWB) finish systems, but these are the exception.

Floor Systems Construction of the hangar building is concrete slab-on-grade throughout; second floor offices and support spaces are constructed with steel framing and concrete slabs. The hangar bay has epoxy floor coating in much of the hangar area.

Newly installed 12- x 12-inch floor tile can be found throughout many of the first and second floor offices; however, older asbestos-containing floor tile remain underneath much of the new tile.

All restrooms have one-inch ceramic floor tiles for floor finishes. Many offices have carpeting.

Asbestos Summary The AHERA regulation, 40 Code of Federal Regulations (CFR) 763, is the primary governing regulation when performing asbestos surveys. This regulation was originally enacted for school buildings, but has since been applied to public and commercial

December 1, 2012 4 Helix Design Group, Inc.

buildings by the Asbestos School Hazard Abatement Reauthorization Act (ASHARA) in 1994 and by the Occupational Safety and Health Administration’s (OSHA) worker protection regulations in 1995, specifically 29 CFR 1926.1101(k).

Puget Sound Clean Air Agency (PSCAA) also requires compliance with AHERA’s survey and sampling requirements. This applies to any renovation or demolition activities where suspect asbestos-containing material (ACM) may be disturbed. PSCAA is a local agency that receives statutory authority from the U.S. Environmental Protection Agency (EPA) to enforce environmental regulations.

AHERA divides suspect ACM into three categories; “surfacing materials” (i.e., sprayed fireproofing, popcorn ceiling texture, etc.), “thermal system insulation” (TSI) (i.e., pipe or building insulation, etc.), and “miscellaneous materials” (i.e., flooring material, roofing, construction mastics, etc.). Building 3041 was surveyed for these materials as they relate to the hangar upgrade project and sampled as required (total of 61 samples). For a complete listing of suspect materials sampled, see Appendix D.

Sampling locations are indicated on the drawings in Appendix E. Table 1 below lists asbestos-containing materials identified in the building that will be impacted by this renovation or require communication of hazards to construction workers during the project. Additionally, contractors shall incorporate findings from the previous survey in any site work plans or hazard communication programs:

present. Five samples were collected and analyzed for asbestos content; no asbestos was detected.

Thermal System Insulation Pipe fitting insulation (Prezant, PF-1, PF-2 & PF-3). Prezant identified pipe fitting insulation materials in 1993 and sampled fittings in the boiler room and hangar bay. All nine samples collected contained between 10% and 15% Amosite asbestos. Most of the insulation on mechanical systems that are accessible to passing personnel and equipment has been replaced and was visually determined fiberglass with polyvinyl chloride (PVC) covering and fiberglass batt insulation underneath. Much of the original insulation systems are present in higher elevations and in rooms where the location does not present a damage hazard.

Pipe insulation mag (Prezant, PI-1). Located in the boiler room, Prezant had collected three samples; all of them contained both Chrysotile and Amosite asbestos. This material is no longer present.

Pipe insulation (Prezant PI-2). This white insulation was sampled in room 109, the hangar, and room 216 and most likely was fiberglass. Three samples were collected and no asbestos was detected.

Exterior insulation panels (MTNW). MTNW reviewed as-built drawings as part of this project and noted exterior insulation was specified as rigid insulation or cement asbestos board faced insulation. Currently installed insulation was visually determined non-asbestos fiberglass and no suspect facing was present.

Miscellaneous Materials 9- x 9-inch vinyl asbestos floor tile and mastic (Prezant, FT-1, FT-2, &

FT-5). Nine samples were collected and analyzed for asbestos content with <1% to 5% Chrysotile asbestos identified. MTNW observed floor tile underneath non-asbestos tile and carpeting and has assumed it is this material.

12- x 12-inch vinyl asbestos floor tile and mastic (Prezant, FT-3 & FT-4).

Prezant collected six samples of 12-inch floor tile and analyzed them by PLM with results of 0% to 2% Chrysotile asbestos. Transmission electron microscopy was performed on three of the samples with results ranging from 1% to 10% Chrysotile asbestos. MTNW observed floor tile underneath non-asbestos tile and carpeting and has assumed it is this material.

Gypsum wall board systems (Prezant). GWB is present in small quantities on the second floor of the maintenance wings. Textures were not observed on any of the GWB systems and all indications point to typical system application of joint compound (seams and nail/screw heads). Prezant collected three

December 1, 2012 7 Helix Design Group, Inc.

samples in 1993 (WB-1) and analyzed for asbestos content; no asbestos was detected.

Window putty (Prezant). Original, or what appears to be original exterior windows are aluminum metal-framed and have metal framing holding the glass in place. Where windows have been replaced, the metal is missing and window putty has been used to hold the glass in place (WP-1). Prezant collected three samples of the putty in 1993 and had them analyzed for asbestos content; all three samples contained asbestos content albeit, none greater than one percent. <1% to 1% Chrysotile asbestos is present in the window putty.

Metal siding screw head gasket (HM-01). Exterior metal siding is held in place with sheet metal screws which have this black gasket material. Four samples were collected, one from each side of the building, and analyzed for asbestos content; no asbestos was detected.

Soft – gray window/door/siding caulking (HM-02). This caulking is located on windows, doors, and siding on the exterior of the building and has the appearance of being a newer caulk material. Three samples were collected and analyzed for asbestos content; no asbestos was detected.

White window frame caulking (HM-03). Aluminum framed windows have a metal trim and this caulking is located where the two terminate on the perimeter of the window system. Three samples were collected and analyzed for asbestos content; 2% Chrysotile asbestos was detected in all three samples.

Concrete stem wall coating/paint (HM-04). This material is located on the exterior stem wall and runs the perimeter of the building except for where the hangar doors are located. Three samples were collected and analyzed for asbestos content; no asbestos was detected.

Metal siding coating/paint (HM-05). Exterior wall covering consists of corrugated sheet metal over an insulated panel. Inspection of the siding did not reveal evidence of galbestos siding material. Four samples of the coating/paint were collected, one from each side of the building, and analyzed for asbestos content; no asbestos was detected.

Screw head caulking (HM-06). Located on a select few of the exterior screws holding the corrugated metal panels in place, this material appeared to have been added where leaks may have occurred. Three samples were collected and analyzed for asbestos content; no asbestos was detected.

Horizontal foundation caulking (HM-07). On the exterior of the building along the bottom of the concrete stem wall is a reveal that has this caulking material. Three samples were collected and analyzed for asbestos content;

no asbestos was detected.

December 1, 2012 8 Helix Design Group, Inc.

Gray – hard caulking (HM-08). This caulking material is located on the building exterior at protruding metal framing on doors and windows where the metal siding terminates. Three samples were collected and analyzed for asbestos content; 2% to 3% Chrysotile asbestos was detected in all three samples.

Window frame/glass gasket (HM-09). Glass in the aluminum windows has this gasket material between the glass and the aluminum frame. Med-Tox collected four samples of the material (one sample from each floor on the north and south sides of the building where the windows are located) and analyzed them for asbestos content; no asbestos was detected.

CMU grout and paint coating (HM-10). Most walls in the office and maintenance rooms are constructed with CMU which are painted white and without textured finishes (except for restrooms, see HM-11). Three samples were collected of the grout and paint coatings and analyzed for asbestos content; no asbestos was detected. MTNW inspected openings and holes for vermiculite insulation inside CMU walls and did not visually observe evidence of it being present.

1-inch ceramic floor tile grout (HM-12). In previous reports, this material was assumed asbestos-containing. It is located in the building restrooms. Med- Tox collected two samples and analyzed them for asbestos content; no asbestos was detected.

Ceramic masonry unit grout (HM-13). All of the buildings restrooms have walls constructed with this ceramic masonry unit tile on the bottom four feet of the wall with typical CMU on the upper portions of the walls. Two samples of the grout were collected and analyzed for asbestos content; no asbestos was detected.

Black sink undercoating (HM-14). One stainless steel sink located in the first floor break room on the north side of the building had this soundproof coating spray applied to the underside of the sink. One sample was collected and analyzed for asbestos content; no asbestos was detected.

CMU/door caulking (HM-15). Every door installed in the CMU walls has this caulking where the door frame and CMU meet. It is painted white but is a gray caulking material. Three samples were collected and analyzed for asbestos content; 5% Chrysotile asbestos was detected in two of the three samples.

Brown 4-inch cove base and adhesive (HM-16). This newer floor finish material is throughout the offices and maintenance areas where 12-inch floor tile is present. Three samples were collected, including multiple layers of new and old adhesive underneath, and analyzed for asbestos content; no asbestos was detected.

Beige with streaks 12- x 12-inch floor tile and adhesive (HM-17). Some of the offices and support areas in the building wings have this flooring finish

material on concrete substrates and on asbestos floor tile. Three samples were collected and analyzed for asbestos content; no asbestos was detected.

Blue carpeting with tan adhesive (HM-18). Carpeting installed in some of the wing support office areas is glued with this tan adhesive. Three samples were collected and analyzed for asbestos content; no asbestos was detected.

In many locations this carpeting is installed over asbestos floor tile and mastic.

Gray 4-inch cove base and adhesive (HM-19). This newer floor finish material is throughout the offices and maintenance areas where 12-inch floor tile is present. Three samples were collected, including multiple layers of new and old adhesive underneath, and analyzed for asbestos content; no asbestos was detected.

Gray floor caulking (H-20). Concrete floor expansion joints in the east side of the hangar bay are sealed with this gray caulking. One sample was collected and analyzed for asbestos content; no asbestos was detected.

Black floor caulking (H-21). Concrete floor expansion joints in the west side of the hangar bay are sealed with this black caulking. One sample was collected and analyzed for asbestos content; no asbestos was detected.

Gaskets (MTNW). Various gaskets were observed on mechanical and fire sprinkler piping. These are assumed asbestos-containing.

Fire doors (MTNW). Personnel doors and large rolling fire doors are present in the building and are scheduled to be replaced as part of this project. The smaller personnel doors have a varied history of replacement and many are newer within the last decade. However, due to occupancy and fire rating, none of the doors were destructively investigated and therefore are assumed to contain asbestos insulation.

Table 2 below lists all suspect asbestos-containing materials that have been determined non-asbestos; materials with detectable but less than 1% asbestos content are identified in the material descriptions above.

Lead-Based Paint Summary Lead was commonly used in most paint products until 1978, when it was banned from residential paints at concentrations greater than 600 parts per million (ppm); however, commercial applications with lead were still utilized and are still available. Lead is poisonous to the human body and presents a potential health hazard during any kind of disturbance (such as maintenance, including grinding, welding, and cutting) and if improperly disposed, where lead can enter drinking water supplies.

December 1, 2012 11 Helix Design Group, Inc.

EPA defines lead-based paint as a concentration of 1.0 milligram per centimeter squared (mg/cm2) or greater by X-Ray fluorescence (XRF) or 0.5 percent by weight or greater by total lead analysis (equivalent to 5,000 ppm). This EPA action level triggers requirements for protection of the environment, maintenance workers, and building occupants. It also triggers training and certification requirements for inspectors, project designers, contractors, supervisors, and workers. Although the training requirements only apply to certain residential structures and/or child occupied facilities at this time, they could apply to this type of property sometime in the future.

OSHA worker protection regulations have not defined a minimum concentration for regulating lead, and has clarified that lead at any detectable concentration shall be considered regulated (29 CFR 1926.62).

Lead in Painted Surfaces Interior and exterior painted surfaces were tested for LBP using bulk sample collection and chemical analysis. A total of eight (8) paint chip samples were collected. Analytical results are provided in Table 3.

Waste Designation Survey The Toxicity Characteristic Leaching Procedure (TCLP) procedure is used to simulate the transfer of lead from lead-containing waste into the ground water system upon co-disposal of the lead-containing waste and municipal solid waste in unlined solid waste landfills. The TCLP attempts to simulate rain or ground water leaching, or both, of lead

December 1, 2012 12 Helix Design Group, Inc.

from the buried waste. In order for the procedure to yield an accurate predictor of the subsurface (in-ground) leaching process, a representative sample of the volume of the waste must be selected and submitted for leaching and analysis. The result of the sampling, leaching, and analysis process is used to determine the waste handling and disposal protocols to be followed and to document compliance with applicable laws, regulations, and requirements. WAC 173-303 Dangerous Waste Regulations defines hazardous waste as it relates to lead by toxicity as 5.0 milligrams per Liter (mg/L) by

TCLP.

A visual inspection of the survey area was conducted to separate the major components of the structures to be demolished into two categories:

• Recyclables. It is anticipated that many of the metal items (i.e., metal piping, tanks, door frames, doors, handrails, flashing, aluminum window frames, etc.) and un-painted clean concrete materials in the survey area will be recycled or reused. These items were not tested for waste pre-designation. Additionally, glass is recyclable and not included in the waste designation survey.

• Potential Wastes. As the project is defined, the primary waste items with paint coatings that are not recyclable include painted CMU and concrete.

Paint chip sampling identified trace levels of lead in these materials.

Combined with the entire CMU block or concrete wall, the lead content is not significant and would not result in a hazardous waste.

• Assumed hazardous waste. Paint, if removed from building components is assumed hazardous waste due to the lead content.

Other Hazardous Building Materials

PCB Light Ballasts and Fluorescent Light Tubes

Older fluorescent light ballasts have small capacitors that may contain high concentrations of PCBs. Nearly all ballasts manufactured before 1979 contain PCBs.

All ballasts manufactured after July 1, 1978 that do not contain PCBs are required to be clearly marked "No PCBs". Unmarked ballasts or ballasts without a date code should be assumed to be PCB ballasts. PCBs are toxic chemicals according to the EPA.

While there is only a small amount, about one ounce, of PCBs in each light ballast capacitor, there are a large number of ballasts in the United States. About half of the one billion ballasts, estimated as currently installed, were manufactured before 1979 and usually contain PCBs. Ballasts manufactured after 1978 may contain a PCB replacement called Di (2-ethylhexyl) phthalate (DEHP), a probable human carcinogen.

In any case, ballasts should not be disassembled for disposal but collected and sent to a certified recycling/disposal facility. Table 5 provides a summary of these items in the building:

December 1, 2012 13 Helix Design Group, Inc.

Many of the lights in Building 3041 are newer and will not have PCB or DEHP ballasts.

PCB in Caulking and Paint

PCB were used in paint and caulk formulations as drying oils (resins) and plasticizers or softening agents (liquids). Concrete surfaces and equipment, as well as marine or waterproofing applications, used at Federal installations and in the manufacturing and industrial sectors may have painted surfaces contaminated with PCBs.

PCBs were tested in representative caulking, paints, and sealants on the interior and exterior of Building 3041. Table 5 below provides a summary of PCB sample results.

Laboratory Analytical Methods

Asbestos-Containing Materials Bulk samples were analyzed by Polarized Light Microscopy (PLM) dispersion staining EPA Method 600/R-93/116 by Seattle Asbestos Test (SAT). SAT is accredited through the National Voluntary Laboratory Accreditation Program (NVLAP) of the U. S.

Department of Commerce. This accreditation does not constitute endorsement, but rather a finding of laboratory competence. The NVLAP participant number is 200768-0 (certification in Appendix F). Copies of the laboratory analytical reports are provided in Appendix G.

Lead-Based Paint Bulk paint chip samples were submitted to EMSL Analytical Inc. (EMSL) for analysis. A total of eight (8) paint chip samples were analyzed for lead using atomic absorption spectroscopy (AAS) to determine the presence and percentage of lead. Procedures for analyzing metals are found in the ASTM D-3335-78 and EPA Method Manual SW-846, Method 6010B.

Analytical results are provided in Appendix H. EMSL’s laboratory certification is attached in Appendix I.

Comments and Recommendations

Asbestos-Containing Materials We recommend that this survey report be placed on-site during renovation and/or selective demolition and copies provided to the contractor(s) bidding and performing work. The Washington Industrial Safety and Health Administration (WISHA), OSHA and PSCAA require that the report be on-site and available for review during the entire project duration.

Additional destructive investigation and sampling will be required prior to and during renovation activities including, but not limited to the following:

1. The majority of pipe insulation is present throughout the building and visible due to the lack of ceiling finishes. Perform destructive investigation inside wall and ceiling cavities to verify asbestos pipe fitting or insulation is not hidden or present if work will impact these types of areas. More specifically, restrooms have concealed pipe chases that, according to as-built drawings, likely have asbestos pipe insulation and contaminated debris.

2. Entry doors were not destructively investigated due to building occupancy and potential fire rating. During renovation, inspect every door and door jamb scheduled for demolition for suspect asbestos insulation material before removal.

3. Electrical systems were not sampled due to being energized and in use. If suspect ACM electrical components are observed during construction, do not disturb before evaluation and/or sampling by an AHERA accredited building inspector.

4. Only materials expected to be impacted by this renovation were investigated as part of this survey. This investigation did not include subsurface materials that may contain asbestos.

Materials in this report with asbestos content less than 1% will require special handling during removal and/or demolition as detailed in WISHA Regional Directive 23.30, specifically, section b.2 “wallboard systems with less than 1% asbestos content”. A copy of this directive is available at:

Lead-Based Paint All painted surfaces were tested and found to contain at least trace levels of lead in paint, therefore requiring compliance with 29 CFR 1926.62 and WAC 296-155-176 during any disturbance of painted surfaces. This requirement will apply to all construction trades, unless painted surfaces are removed during demolition activities, which is typically cost prohibitive.

Based on paint chip sampling, paint wastes will likely fail waste designation if disposed as a single waste stream. MTNW recommends sampling painted construction debris by TCLP during construction and once the waste stream has been determined.

The interior concrete demising walls have high levels of lead in the paint coatings; these systems will remain in place as part of this project but most likely will be impacted by renovations. Peeling paint or core drills of this system will likely fail waste designation and depending on the project scope, may require disposal as a hazardous waste.

PCBs PCB-containing paint and caulking, will require removal or disposal of the components as a PCB containing waste. Hangar floor caulking and asbestos caulking on the exterior windows and doors are EPA bulk product waste and will require notification to EPA as part of remediation efforts. Paints with PCB content less than the EPA definition of PCB bulk product waste does not require notification prior to disposal as demolition debris with PCB content. Reportedly, asphalt surrounding the building has been in place for the life of the building. Sampling of soils from PCBs leaching out of the paint and caulking should not be necessary.

During demolition, the abatement contractor should be tasked with dismantling light fixtures, checking for PCB-free labels, and recycling the light tubes. Ballasts without PCB-free labels are considered PCB-containing and must be disposed as a hazardous waste; all other light ballasts can be recycled.

JBLM will need to obtain or provide the EPA/State identification number for legal disposal of PCB light ballasts if found to be present. The contractor will need to provide the hazardous waste manifest used to track disposal in accordance with 40 CFR 761.50, 40 CFR 761.62, and WAC 173-303.

Additionally, PCB work procedures for proper removal and protection of workers should be provided to contractors bidding and performing the work in accordance with WAC 296-155 and WAC 296-841.

Other Hazardous Building Materials No other suspect hazardous building materials were observed that will affect the scope of this renovation.

Limitations

A good faith effort has been made to identify ACM, LBP, and other HBM for the hangar renovation project. This survey was performed for this specific project and not complete demolition of the building. Additionally, the building was occupied during the survey.

Additional destructive investigation and sampling may be required depending on inaccessible mechanical system spaces and/or mechanical/electrical system routing.

Sampling was performed consistent with the level of care and skill ordinarily exercised by professionals currently practicing under similar conditions in the area. No other warranty, expressed or implied, is made.

This report has been prepared for the exclusive use of Helix Design Group, Inc,. and its’ designates for this project only. The analyses, conclusions, and recommendations presented in this report are based on conditions encountered at the time of our study and our experience and judgment. MTNW cannot be held responsible for interpretation by others of the data contained in this report; any use of this report shall include the entire document. This survey is not intended for use as abatement plans and/or specifications which MTNW recommends for regulatory compliance.
