AMENDMENT 0003

RFIs

What is anticipated for the duration for the guard to demobilize from a phase and move in to the previously completed phase? 1-2 weeks? Trying to anticipate our demobilization and phasing between areas.

Answer: Phase one contractor will not be impacted. Phase two contractor will not be impacted.

Phase three contractor may have to work around some occupants, but should be minimal impact.

Please confirm that the facility elevators may be used for both manpower and material distribution. Is there existing wall protection padding that can be used? Is it anticipated that if the elevators are allowed to be utilized, any service required during that phase of the project would be the responsibility of the contractor?

Answer: The elevators may be used during construction. Contractor will be required to provide padding. If elevator requires service, the govt will service, but repair or service timeline may affect contractor's ability to use during construction.

Please confirm that outside the south end of the hanger may be used for staging during the first phase. This area would be anticipated to be required to be fenced. It was understood that for phases 2 and 3, the staging would move to the north side of the hanger.

Answer: South end of hangar ramp space will be available to contractor as a material/equipment laydown area during Phase 1. During Phase 2 & 3, this area will move to the north end of the hangar.

Please confirm that there will be access from the flight line adjacent to the hanger for cranes and equipment to get materials up to the roof level.

Answer: Access to the flight line adjacent to hangar facility is allowed to move material and equipment up to the roof level. Crane heights 100' and above requires FAA approval and is a 45 day lead time once they receive the request. Request will be processed through the govt.

What size is the tail door? The plans label the door as #221AA but that number does not appear in the door schedule.

Answer: See note on sheet A1-02 which indicates door number to see in door schedule. In the Door Schedule the size is listed as 14' wide x 13' high, which was taken from original drawings and will need to be field measured before ordering.

There are 3 hollow metal doors (per door schedule 134-1, 134-2, 134-3) located within the hangar door. Are these 3 doors required to be ADA compliant, thus no bottom chord on the hangar door, at these 3 locations.

Answer: Not ADA compliant and no bottom chord at these doors.

How are the liner panels secured to the inside of the hangar door (bolt, weld, other).

Answer: The hangar flat sheet steel door covering for both the interior and exterior face are specified in spec Section 08 34 16.20 Bi-Parting Bottom Rolling Hangar Door, this includes the attachment methods.

Are the liner panels the full height of the door?

Answer: Yes, the flat sheet steel door covering are full height of doors both sides.

HAZMAT Questions

With regards to the Asbestos and Lead Removal the following are our responses to them:

I need the Asbestos, Lead and Hazardous Materials Survey Report, dated April 24, 2015; there are questions regarding the spray-applied fire-proofing along the hangar doors.

Answer: Attached is the Hazardous Material Survey Report dated April 24, 2015.

There appears to be another wall surface beneath the corrugated asbestos panels. Is this wall to be left in-place, as-is, after the asbestos panels are removed?

Answer: Per the plans for the Hangar door pockets and associated roof as indicated on sheet A2-01, and sections 5/A4-01, 6/A4-01, & 5/A5-04 the existing walls and roofs at the asbestos panels are to be removed leaving only the steel structure which the new construction will be supported on.

There is lead-based paint in areas, but is removal of this paint a requirement or are these lead results just included as information for anyone who may be working on or around these materials?

Answer: The information is included for information for anyone who may be working on or around these materials where the lead-based paint will remain. Refer to the demolition notes for specific areas or items to be removed per the contract document that have lead-based paint.

Also refer the hazardous material drawing AB0-01 through ABO-04, and specification Section 02 83013.00 20 Lead In Construction where these items are to be removed.

ELECTRICAL

Specification Section 261116.12- Secondary Unit Substations with Switchboard Secondary, Section 2.5, A. 1. States "Switchgear shall be arc-resistant, complying with IEEE C37.20.7, Type 2C". Is Arc-Resistant type actually required for this project?

Answer: Specification 261116.12, paragraph 2.5 A.1 should be deleted. Arc resistant switchboards will not be required.

1. Drawing E3-02

a. Note #11 – This note is not used on the drawing, should it be? If so, location?

Answer: Note #11 marker should point to monitor location at west wall of 138, south of grid line "H".

2. Drawing E3-03

a. Notes #7 & 12 - Should these devices be remove and relocate or do the existing devices not require any work?

Answer: Note #7 - existing cable tray to remain. Minor changes may need to be performed to avoid conflicts with new mechanical. For bidding, assume (3) separate 5' lengths will be shifted 24" to avoid conflicts.

Answer: Note #12 - the existing power pole to remain. New devices installed in existing pole.

b. Note #14 - Nothing listed – should there be a discovery allowance for this note?

Or will this be an approved change order once the work required is identified and defined?

Answer: For pricing purposes, assume 6 telecom outlets in E106A, 6 in E124, and 4 in E131, evenly distributed around room. Locations to be verified with gov’t.

3. E3-04

a. Note #8 & 17 – Same as #2 above Answer: Note #8 - existing cable tray to remain. Minor changes may need to be performed to avoid conflicts with new mechanical. For pricing, assume (1) 5' length will be shifted 24" to avoid conflicts.

Note #17 – Only work required beyond the work described above is the connection of the new cable tray to the existing.

4. E3-01 through E3-07

a. Special systems Note 3.B, 4.B & 5.B. There are no locations for the flat panel display devices shown on the Specialty System drawings on the entire project. Is this correct or are there device locations? If so, location(s)?

Answer: There are no B type panel display boxes. Type A only.

5. E7-02

a. Detail #2 – The upper left side of this detail (next to Comm W224D Room) shows a new rack, TGB, Cable Tray, etc. However, there is no room number designation or location to where this equipment is to be located. Please clarify this location/room number.

Answer: It appears this room is a leftover from a previous design option. Please disregard the work shown on drawing E7-02, detail #1, in location shown above W155 and to the left of

COMM W224D.

b. Detail #4 – ½ shaded triangle – 4-Port Outlet – indicates a required fiber to each drop. Is this correct and fiber IS required? There are only (7) seven of these location shown throughout the entire project.

Answer: Detail #2 – Yes, this is correct, and fiber is required.

6. E2-01

a. Note #16 – Per the rooms where Note #16 is located, there is typically only (1) one new circuit to the room. How are 50% of the receptacles designed to shut off automatically when the space is unoccupied? Per 90.1-2010, Section 8.4.2, we will need to know the design, given the exceptions and safety concerns per office/room location requiring this energy efficiency. 8.4.2 – Automatic Receptacle Control Function – can be local. Therefore; do you want local control at each receptacle (a controller can be plugged into each outlet) or does an additional circuit need to be added to each room? Specifically, which outlets in these rooms will require to be shut-off? Which receptacles will require 24-hr operational power?

Answer: The intent of the design was to have circuiting similar to lighting circuits: circuit is run to the space, then divided into un-switched leg to the uncontrolled receptacles, and switched leg through the room controller, controlling the switched receptacles. For pricing purposes: switch one duplex receptacle at the quad receptacle locations, and switch one receptacle at duplex receptacle locations (split duplex). The owner will need to address the exact locations of receptacles that will fall under the exceptions to 8.4.2.

7. E2-02

a. Who is responsible for furnishing the following noted pushbuttons? If electrical, do you have desired specification requirements for each?

i. Note #7 – EM Shut off – Test Bench Electrical – momentary contact switch.

ii. Note #8 – up/down P/B for Hangar Cable Reel Electrical – 2 button momentary contact switch.

iii. Note #18 – EM Shutdown P/B – HVAC Electrical - momentary contact switch.

iv. Note #15 – Shutdown - 400HZ Control Station Electrical – on/off sustained contact.

8. E2-03

a. Is there any work required in Room FLAM E131B? There is nothing shown, however, sheet Note #16 indicates all work to be Class I, Div 2.

Answer: No work in this space.

9. E2-06

a. Where is transformer TC2E, which feeds Panel C2E, located at?

Answer: Install in electrical room E200B adjacent to Comm E200A.

MECHANICAL:

Section 237313 – Modular Indoor Central-Station Air-Handling Units – Revisions as Listed Below The physical size of air handling units is critical to the project as shown on the drawings. These instructions are intended to allow flexibility in the space required. Access Doors (2.2.C.3) are to be full height up to a maximum of 60 inches. They may be as short at 36 inches if required to swing and avoid duct or pipe conflicts. They may be 12” wide if the specified 18” is not practical.

The unit casing (2.2.A) is to be galvanized. Factory primer is not required as the units will not be painted.

Nebraska Air National Guard – Building 600 Hazardous Materials Survey Report

April 24, 2015 14-00429 Page 1

1.0 SURVEY OVERVIEW

The Nebraska Air National Guard Building 600, located at 2433 NW 24 th

St. in Lincoln, Nebraska, was inspected for asbestos-containing materials (ACMs), lead-based painted building components, lead-containing materials and miscellaneous hazardous materials by representatives of AMI Environmental. The building is a two story structure with a hangar area, and totals approximately 83,000 square feet. The survey area was inclusive of all accessible interior areas and exterior surfaces of the building with the exception of the roof.

The survey was initiated by Major Otte of the Nebraska Air National Guard Lincoln, NE, division.

The asbestos inspection was conducted by Mr. Ben Milliken on February 24

& 25 th

, 2015.

Mr. Milliken has completed the requisite training for accreditation as an asbestos inspector at a state-approved training provider, as required by the Toxic Substances Control Act (TSCA

Title II) and is licensed in the State of Nebraska to conduct asbestos inspections. Mr.

Milliken’s United States Environmental Protection Agency (EPA) and State of Nebraska building inspector numbers are ME69401E0C8BB34D9 and 1188, respectively.

The lead inspection was conducted by Mr. Chuck Epperson on February 24

, 2015. While there is no licensing requirement for the lead survey performed, Mr. Epperson has completed the requisite training for RMD’s LPA-1 Lead Paint Inspection System.

Mr. Milliken conducted the miscellaneous hazardous materials inspection. There are no formal licensing requirements for this discipline.

2.0 SURVEY METHODOLOGY

2.1 Asbestos-Containing Materials

2.1.1 Applicable Definitions

The EPA and the Occupational Safety and Health Administration (OSHA) define ACMs as any material that contains greater than one percent asbestos, as determined by visual area estimation (microscopic analysis).

By definition, friable ACMs contain more than one percent asbestos, release fibers more readily and, when dry, can be crumbled, pulverized or reduced to powder by hand pressure. In contrast, non-friable ACMs contain more than one percent asbestos but, when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure.

Some materials contain one percent or less asbestos. While these materials are not ACM’s by definition, they are still regulated by OSHA, but to a lesser degree.

2.1.2 Bulk Sampling

The asbestos inspection was performed in accordance with EPA’s National Emission

Standard for Hazardous Air Pollutants (NESHAP), 40 CFR 61.

April 24, 2015 14-00429 Page 2

A total of 79 asbestos bulk samples were collected for laboratory analysis from 23 suspect materials identified during the asbestos inspection and return visits. The samples were submitted to an EPA accredited laboratory, EMSL Analytical, Inc. (EMSL), located at

200 Rout 130 North, Cinnaminson, New Jersey. EMSL was instructed to perform

Polarized Light Microscopy (PLM) analysis, utilizing dispersion staining techniques (ref:

EPA Method 600/M4-82-020) on the samples. The lab was instructed to “stop on first positive,” meaning it is unnecessary to continue analyzing samples in the same homogenous material group(s), since the material has been determined to contain asbestos greater than one-percent.

Of the 79 samples submitted, 18 contained multiple layers, for a total of 97 heterogeneous applications requiring analysis. Heterogeneous applications are individual layers of different materials contained within a single bulk sample, each of which must be analyzed individually to determine its asbestos content (e.g. vinyl floor tiles and mastic; cove base and mastic; and drywall and joint compound).

Please refer to Table 1 in Appendix A for a complete listing of all suspect materials identified and sampled for asbestos.

2.1.3 Quantification Method Analysis

EPA regulations allow materials determined to contain less than 10 percent asbestos utilizing a visual estimate quantification method, such as PLM analysis, to be treated as non-asbestos containing if the material is re-analyzed using one of two quantification methods and determined to contain one percent or less of asbestos. The two acceptable quantification methods are point count analysis and TEM Chatfield analysis.

Quantification methods are more time-consuming and more expensive analytical procedures that are occasionally used to more accurately determine the amount of asbestos in certain samples. Because of their higher cost and the acceptable accuracy of the less expensive visual estimation method, laboratories do not typically perform quantification analyses unless specifically requested.

The quantification method known as point counting analysis is used for most ACM types, except floor tile. The organic matrix composition of floor tile precludes the use of point count analysis to more accurately determine asbestos amounts within a sample. Therefore, TEM Chatfield analysis—which effectively removes all organic materials, leaving only asbestos behind—is necessary to provide a more precise percentage of asbestos content in floor tile.

2.1.4 Survey Limitations

At the discretion of the inspector, samples were not collected from materials that are not accessible and/or require dismantling or damage to the finished surfaces (such as walls and ridged ceilings). Suspect ACMs that are not accessible may include thermal system insulation on mechanical lines inside finished interior walls and ceilings, or materials in areas not accessible due to occupancy privacy and related concerns. These applications should be identified at the time of renovation or demolition. Sampling of these materials

April 24, 2015 14-00429 Page 3 may not be necessary if these materials are presumed to be asbestos-containing or if the materials discovered within the concealed spaces are determined, by a licensed asbestos inspector, to be homogenous to other materials that were sampled.

There were no limitations encountered during the survey. The roof was not sampled at the request of the escort.

2.2 Lead-Based Painted Building Components and Lead-Containing Materials

2.2.1 X-Ray Fluorescence Testing

A portable X-ray fluorescence (XRF) instrument was used for determining the presence and concentration of lead in the facility.

Portable XRF instruments expose painted surfaces, porcelain, glazed block, vinyl and other possible lead-containing materials to X-rays or other high energy radiation—such as gamma rays—which causes lead to emit X-rays with a characteristic frequency. The intensity of this radiation is measured by the instrument’s detector, and is then converted into a number that represents the amount of lead in the paint per unit area, usually milligrams per square centimeter (mg/cm2).

A total of 144 readings, including 12 calibration readings, were collected from suspect paints, coatings and materials to determine the concentration of lead present.

2.2.2 Classification of XRF Results

XRF results are classified as positive, negative or inconclusive. A positive classification indicates lead is present at or above the standard (determined by the EPA to be 1.0 mg/cm2 or higher using XRF). A negative classification indicates lead at or above the standard is not present on the sample. An inconclusive classification indicates the XRF test result cannot determine with reasonable certainty whether lead is present at or above the standard.

Please refer to Table 2 in Appendix A for a complete listing of paints, materials and components identified as containing lead levels exceeding the EPA’s action level of 1.0 mg/cm2.

2.3 Miscellaneous Hazardous Materials

AMI noted miscellaneous hazardous materials within the Survey Area. While observed and reported, these materials were not sampled or fully verified. Please refer to Table 3 in

Appendix A for a complete listing of miscellaneous hazardous materials observed.

2.3.1 Mercury Fluorescent Lamps and Thermostats

Mercury has certain characteristics that make it uniquely useful to use in various medical and industrial devices. It is the only metal that exists as a liquid at room temperature.

Mercury expands and contracts according to temperature changes, combines easily with other metals, and conducts electricity.

April 24, 2015 14-00429 Page 4

Gas discharge bulbs (fluorescent light bulbs, high intensity discharge [HID] lamps) contain mercury vapor. Most of the mercury associated with a fluorescent bulb and HID is encountered in the phosphor coating on the inside of the bulb or lamp as divalent mercury.

Fluorescent bulbs come in various shapes and sizes (straight, u-bent, compact and circular). Mercury content averages 30 mg. Newer lamps with green tips contain only traces of mercury.

Thermostats, temperature and blood pressure gauges, displacement relays and contacts and silent switches contain mercury in a liquid form. Mercury is located in a glass vial, tube or hermetically sealed container within the item.

Please refer to Table 3 for more information about the materials containing mercury observed in the survey area.

2.3.2 Ozone Depleting Substances (ODS)

Known as ozone depleting substances, Chlorofluorocarbon (CFCs) are highly effective refrigerants that were developed in response to the pressing need to eliminate toxic and flammable substances, such as sulfur dioxide and ammonia, in refrigeration units and air conditioners.

The most common commercial CFCs were marketed under the trade name Freon.

Commercial CFCs are nonflammable, non-corrosive, nontoxic, odorless, and their vapor pressures and heats of vaporization made them suitable for refrigeration applications.

Under Title VI, Section 608, of the 1990 Clean Air Act (CAA), Freon is classified as a hazardous substance and waste.

Please refer to Table 3 for more information about ozone depleting substances observed in the survey area.

2.3.3 Batteries

Batteries such as nickel-cadmium (Ni-Cd) and small sealed lead-acid batteries, which are found in many common items, including electronic equipment, mobile telephones, portable computers, security systems, exit signs and emergency backup lighting. Batteries may also contain alkalines, mercury, silver and electrolytes. These substances are listed as hazardous substances and waste under Subtitle C of the Resource Conservation and

Recovery Act (RCRA).

Please refer to Table 3 for more information about batteries observed in the survey area.

2.3.4 Low-Level Radioactive Sources

Ionizing smoke detectors use an ionizing chamber and a source of ionizing radiation to detect smoke. This type of smoke detector is common because it is inexpensive and better at detecting smaller amounts of smoke produced by flaming fires. Inside the ionizing

April 24, 2015 14-00429 Page 5 detector is a low-level source (perhaps 1/5000 th of a gram) of americium-241. The radioactive element americium has a half-life of 432 years.

Please refer to Table 3 for more information about low level radioactive sources observed in the survey area.

2.3.5 Fire Suppression Tanks

Fire suppression tanks contain either a compressed liquid, gas or foam that that is used to stop the spread of fire. There are different agents that are rated for use with the different fire ratings. For instance, Halon is rated for class A, B and C fires, whereas water is very effective on class A fires, but not class B or C.

Please refer to Table 3 for more information about the tanks observed in the survey area

3.0 SUMMARY OF SURVEY FINDINGS

Below is a brief summary of key findings of the survey. Please refer to the tables, schematics and other supporting documentation found in the appendices for complete details of the survey findings.

3.1 Asbestos-Containing Materials

The ACMs identified in the survey area include 6,200 sq. feet of exterior transite paneling.

The panels are located on all sides of the four exterior towers located on each corner of the hangar portion of the building structure.

3.2 Lead-Based Paints and Lead Containing Materials

Lead-based paint was detected in multiple materials. For further clarification and detail on the specific materials and locations, please refer to Table 2. The porcelain mop sink located in the gym closet was the only material identified to contain lead in excess of 1.0 milligrams per square centimeter (mg/cm2).

3.3 Miscellaneous Hazardous Materials

Fluorescent lamps and thermostats were observed throughout the survey area and may contain mercury. Various refrigerators, drinking fountains, and window air conditioner units were also observed that may contain ozone depleting substances. Fire suppressant tanks were observed which may contain compressed regulated substances. Smoke detector units were observed throughout and may contain low-level radiation. Fire exit signs and fire lamps throughout the survey area contain batteries which present environmental hazards if not disposed of properly.

4.0 RISKS AND HAZARDS

April 24, 2015 14-00429 Page 6

4.1 Asbestos-Containing Materials

To be a significant health concern, asbestos fibers must be inhaled. When asbestos fibers are inhaled, they become lodged in the lung tissue or alveoli. Here they clog and scar the tissues, causing the walls of the alveoli to lose their elasticity and useful function in respiration.

Asbestosis (scarring of the lung), lung cancer and Mesothelioma (cancer of the lining of the chest or lining of the abdominal wall) are diseases associated with asbestos exposure.

4.2 Lead-Based Painted Building Components and Lead-Containing Materials

Exposure to lead can be caused by demolition, alteration, friction and deterioration of lead-based painted and lead-containing surfaces. Lead hazards could exist if proper work practices, monitoring, disposal and personal protective equipment are not implemented during disturbance of these surfaces.

Inhalation and ingestion are the major routes of lead exposure. Once in the body, lead is distributed via the bloodstream to red blood cells, soft tissue and bone. The kidneys and gastrointestinal tract eliminate lead in the body very slowly; smaller amounts are lost through perspiration.

Lead in the body can cause serious damage to the central and peripheral nervous system, the cardiovascular system and the kidneys. Exposure to high concentrations of lead can cause mental retardation, convulsions, coma and sometimes death.

4.3 Miscellaneous Hazardous Materials

4.3.1 Mercury Fluorescent Lamps and Thermostats

Exposure to mercury can cause coughing, bronchitis, pneumonia, tremor, insomnia, irritability, headaches, fatigue, weakness, somatitis, weight loss, GI disorder, and can irritate the skin and eyes. Exposure to mercury can occur through inhalation, ingestion, or absorption through the skin. The most common routes are inhalation and ingestion.

Only a small fraction of the mercury is found as a vapor inside the bulb, but this fraction readily escapes when the bulb is broken. The risk of mercury exposure is low to moderate due to the potential for light tubes, HID lamps and thermostat switch tubes to break during handling. Mercury exposure from green tip lamps is considered negligible.

4.3.2 Ozone Depleting Substances (ODS)

The most serious side effect of Freon exposure occurs at the time of initial exposure.

People who have a history of heart problems should be very concerned about Freon because it can cause cardiac arrhythmia (irregular heartbeat), and palpitations at very high concentrations. For people who have a history of heart problems, being exposed to small amounts of Freon from leaking appliances should not pose any significant health risk.

Fortunately, Freon does not have serious, long-term health consequences. It is not a carcinogen, teratogen, or mutagen, and it does not damage the liver. When it is inhaled, it

April 24, 2015 14-00429 Page 7 is rapidly excreted by exhalation, and it is not significantly accumulated in the body. This means that breathing low concentrations of Freon from a leaking refrigerator or air conditioner over a long period of time is unlikely to have a cumulative effect, and thus few, if any, long term health effects.

4.3.3 Batteries

Exposure to the hazardous substances in batteries can lead to severe skin burns, blindness, dermatitis, and cancer, and can cause damages to the kidney, lungs, brain and nervous system. The risk of exposure to personnel removing batteries containing hazardous substances is low, if properly handled. Improperly handling batteries during removal can lead to the batteries leaking or exploding of its contents, causing internal and external burns and irritations.

4.3.4 Low-Level Radioactive Sources

The risk of exposure to personnel removing smoke detectors is extremely low. The radioactive source is extremely small, and well housed within the monitoring device. It is also predominately alpha radiation, which cannot penetrate a sheet of paper and is blocked by several centimeters of air. The americium in the smoke detector could only pose a danger if it were inhaled. Smoke detectors are removed from their mounting bracket intact and sent to a certified recycler for proper source recovery.

4.3.5 Fire Suppression Tanks

Fire suppression tanks are typically misunderstood and in many cases thought to not pose any health risks. There are many different types of agents that are used for fire suppression that could be hazardous. In many cases, it is not the fire suppressant agent itself that poses the threat, but the dispersion method can allow for the opportunity to interrupt or prevent the lungs from exchanging oxygen, resulting in hyoxia. This is where the body builds up with lactic acid, resulting in cardiac arrest.

5.0 RECOMMENDATIONS

5.1 Asbestos-Containing Materials

The purpose of this section is to interpret survey findings and provide preliminary recommendations that may be relevant and appropriate at this time. Because this document is a presentation of investigative findings, recommendations related to future construction activities are inherently general in nature. More specific determinations concerning ACMs impacted by construction that may require removal can be made during the abatement project design process.

5.1.1 General Recommendations

State and/or federal regulations require that ACMs be removed prior to demolition or renovation activities that will impact the ACMs. Depending on the specific renovation work to be performed, certain ACMs may not require removal if they will not be disturbed and do not pose a risk to building occupants or construction trade workers. However, to ensure worker safety and to eliminate future asbestos-related maintenance and

April 24, 2015 14-00429 Page 8 management costs and risks, AMI recommends removal of all identified ACMs in the areas to be renovated. While partial abatement may be technically possible, it is often impractical and not cost-effective.

ACMs not impacted by renovation or demolition activities should be inspected annually and maintained in good condition. ACMs deemed to be in less than good condition (fair or poor) should be repaired or removed and replaced. Such repairs should be performed by qualified persons and in accordance with regulatory guidelines.

5.1.2 Hazardous Conditions Recommendations

No immediately hazardous identified.

5.1.3 Point Count Analysis / TEM Chatfield Analysis Recommendations

No additional point count analysis or TEM Chatfield analysis is recommended at this time.

5.2 Lead-Based Painted Building Components and Lead-Containing Materials

Ultimately, facility owners are liable for their lead-containing hazardous waste from cradle to grave. Therefore, if building materials and components coated with lead-based paint and/or materials containing lead are to be demolished and disposed of, the facility owner is responsible for determining proper disposal f the waste stream. EPA regulations provide two ways to make a determination of whether the waste stream must be classified as hazardous waste. Waste generators can either test the waste using an approved testing method (Toxicity

Characteristic Leaching Procedure [TCLP]), or they can apply knowledge of the hazardous characteristic of the waste.

Based on the initial lead results, AMI recommends TCLP testing be conducted on the existing building materials, painted and unpainted, prior to the start of any renovation or demolition activity.

OSHA also regulates worker exposure to lead. Therefore, any lead-based painted building components or lead-containing materials not removed during renovation should be considered for inclusion in to a facility management plan that ensures employee exposure is below

OSHA action levels and ensures the material will be handled properly and in accordance with applicable regulations. All trade contractors who work in the facility should also be notified of the presence of lead so that they can appropriately monitor and protect workers against lead exposure.

5.3 Miscellaneous Hazardous Materials

AMI recommends that, prior to any demolition, alteration or disturbance, all other hazardous materials (such as PCBs, ODSs, LLRSs and mercury) be identified, removed and disposed of and/or recycled (where allowable) by a licensed contractor, utilizing trained and certified personnel.

6.0 REGULATORY REQUIREMENTS

6.1 Asbestos-Containing Materials

6.1.1 Notification Requirements

EPA’s NESHAP, 40 CFR, Subpart M, 61.145, Standard for Demolition and Renovation, stipulates that an owner of a facility submit proper notification with either the EPA’s regional office and/or the state and local regulatory agency of intention to demolish or renovate. Notifications must be received by the appropriate regulatory agencies 10 working days prior to commencement of asbestos stripping or removal, or other site work.

If the demolition or renovation date changes, or the scope of work is increased by more than 20 percent, another notification must be made.

6.1.2 Removal Requirements

Asbestos removal should be performed by a licensed abatement contractor. The contractor should follow all work practices, worker protection and disposal requirements set forth in the contract specifications and by the Occupational Safety and Health Administration

(OSHA) and the EPA. Relevant regulations include 29 CFR 1910.1001, 29 CFR

1926.1101 and 40 CFR 763.

6.1.3 State of Nebraska Asbestos Removal Regulations

State of Nebraska rigorously regulates the removal of friable asbestos-containing materials and non-friable asbestos containing materials that may become friable during removal, when affected quantities are greater than three square or three linear feet. For a complete understanding of the Nebraska governing asbestos projects, please refer to Title

178, Chapter 22.

6.1.4 OSHA Regulation of <1 Percent Asbestos

While EPA and many states do not regulate materials containing less than one percent asbestos, OSHA regulates materials containing any amount of asbestos.

Pursuant to OSHA Construction Industry Standard, 29 CFR 1926.1101:

(a) Scope and application:

(3) Construction, alteration, repair maintenance, or renovation of structures, substrates or portions thereof, that contain asbestos;

6.2 Lead-Based Painted Building Components and Lead-Containing Materials

6.2.1 Disposal Requirements

The Resource Conservation and Recovery Act (RCRA) classifies lead-containing waste streams as hazardous materials if TCLP levels exceed five parts per million. If TCLP leachable lead levels exceed that threshold, EPA regulations (40 CFR 261) require the waste stream to be handled and disposed of as a hazardous waste. Waste streams

April 24, 2015 14-00429 Page 10 containing less the five parts per million of leachable lead are classified as non-hazardous waste and can be disposed of in a construction and demolition waste landfill.

6.2.2 Construction Requirements

OSHA’s 29 CFR 1926.62 regulates worker exposure to lead during construction activities that include demolition or salvage of structures where lead or materials containing lead are present, as well as removal or encapsulation of lead-containing materials. The standard establishes maximum limits of exposure to lead, including a permissible exposure limit and action level, and should be adhered to during construction and demolition activities.

6.3 Miscellaneous Hazardous Materials

Miscellaneous hazardous materials removal should be conducted in accordance with all applicable federal, state and local requirements.

7.0 BUDGETARY REMEDIATION ESTIMATE

The following budgetary estimates are provided to assist in planning and budgeting any hazardous material removal that you may be considering. Estimates are provided for the primary disciplines associated with asbestos abatement projects. These figures are estimates only; actual costs may vary and are highly dependent upon the abatement bids received.

7.1 Asbestos Project Design

Often referred to as the asbestos abatement specification or work plan, the asbestos project design provides the detailed instructions and guidelines necessary for asbestos removal. It is also used to solicit bids from asbestos contractors to perform the abatement work. The specification includes detailed information about the ACMs to be removed, how the work needs to be performed, project phasing and other issues that impact the performance of the project. The abatement specification may also include the contract documents necessary to execute a contract between the owner and the contractor.

The asbestos project design process normally involves a pre-design site visit to review site conditions and discuss construction plans; production of all specification documents necessary to bid and perform the project; an onsite walkthrough with prospective bidders; and solicitation and compilation of bid results. The actual design process may vary.

Total Budgetary Estimate for Asbestos Project Design: $2,200.00

7.2 Asbestos Abatement

The budgetary estimate for asbestos abatement is based on the removal and disposal of all

ACMs identified via the investigation. Estimates include labor, materials, equipment and project fees for a licensed company to perform the work in accordance with regulatory requirements and standard industry practices. Estimates do not reflect potential areas of savings that may be identified during the work plan development phase. Higher costs may

April 24, 2015 14-00429 Page 11 result from multiple phasing of the project, which normally results in additional mobilization, labor and related costs. Actual costs are also influenced by project scope, the amount of demolition required to get to the ACMs, the time of year the project is bid, and project location.

Total Budgetary Estimate for Asbestos Abatement: $50,000.00

7.3 Air Quality and Compliance Monitoring

Air quality and compliance monitoring are an integral part of asbestos abatement projects, and are needed to protect the owner’s interests and building occupants by ensuring that all asbestos abatement activities are conducted safely and in accordance with the procedures contained in the project specifications and applicable regulations. The budgetary estimate for air quality and compliance monitoring during asbestos abatement activities is based on the estimated number of shifts the abatement contractor will need to complete the project. The actual costs will be determined by the total number of shifts worked by the contractor. The estimate includes all labor, materials, equipment and fees for performing the air quality sampling and analysis, visual inspections, contractor surveillance, and industrial hygiene services necessary for the abatement process; reporting; and project closeout.

Total Budgetary Est. for Air Quality and Compliance Monitoring: $8,000.00
