Part I: Executive Summary

September 11, 2000 iS2e, inc. conducted a Lead-Based Paint (LBP) Inspection (PI) and LBP Risk Assessment (RA) at Quarters No. 66, Inks Dam National Fish Hatchery, Burnet, TX 78611 on August 30, 2000.

The home was occupied at the time of this inspection.

Quarters No.66 is a single story, pitched-roofed, frame and concrete block, single-family home with 3 bedrooms. The home faces to the east. Original construction occurred in 1957, comprising approximately 1182 fe. The home presently houses a single, adult, male, fUll-time NFH employee.

Lead-based paint Inspection results:

Most of the exterior white paint on this home on the wood surfaces is in "poor" or "unsatisfactory" condition and in need of repainting. Most of the exterior white paint on the concrete block walls is in "fair" condition, and also should be repainted sooner rather than later.

Most of the interior paint in this home is rated to be in "good" condition. The amount of lead and concentrations in the interior of this home is indicative of 1950s or early 1960s interior paint.

Lead-based paint Risk Assessment results:

A. Recommended Solutions for Lead Hazards Identified:

1. Exterior Lead Paint Hazard #1:

a. The exterior white paint on the overhead garage door was rated to be in "unsatisfactory" condition, and contains more than 10ft2 of LBP. Based on the age and condition of the door, it will be cost effective to replace the door.

The LBP on the Garage doorjambs should be chemically stripped and the jambs then primed and repainted.

B. Estimated Costs to Repair Lead Hazards Identified:

1. Repair of Jambs and Replacement Cost for the Garage Door-Hazard #1:

a. Cost estimate to replace the Garage Door is $600.00. Cost estimate to repair the Garage doorjambs is $200.

The U.S. Fish and Wildlife Service is currently developing formal policy and guidance on training for managers, employees and residents. The training will include general lead awareness, work practice requirements, OSHA lead in construction standards, and U.S. Fish and Wildlife Service policy requirements concerning lead.

September 11, 2000

For any activity that would disturb surfaces identified as having lead, notify Terry Clayton with the Environmental and Facility Compliance Office at (303) 984-6867 or Bernie Freeman, the Regional Compliance Officer, at (505) 984-7956 prior to beginning work. Any construction activities that affect the preceding paint films (including sanding and demolition) must be initiated by workers wearing respiratory protection, and who have received proper training in the handling of lead contaminated materials.

Part II:

September 11, 2000

Lead-Based Paint Definitions and Standards

A. Definitions:

1. Lead-Based Paint Inspection-defines and reports on the exact location of any/all painted surfaces that contain LBP by the HUD/EPA Interim Standard*.

*Note The term "Standard" is used interchangeably with "Interim Standard". All of the HUD Guidelines Standards and EPA's Work Practice Standards are, in fact, Interim Standards, meaning that they may be subject to regulatory change with new data that supports a change to the "Standard". HUD's 1012 and 1013 Regulation alters the exterior damaged paint "Standard" from 10fe to 20ft2

EPA's TASCA 403 Regulation, when published in final form, will alter the 400PPM soil "Standard" (limit) to an "Area of Concern" (vice a limit). "Standards" can also be "action levels", and in many cases are "action levels".

2. Lead-Based Paint Risk Assessment-A Risk Assessment is an onsite investigation of a residential dwelling for Lead-Based Paint (LBP) "hazards", that includes, but may not be limited to, a visual inspection, limited environmental samplings (assays) of deteriorated paint**, soil and dust. The assays may be accomplished via XRF or laboratory analysis of paint chip samples, or a combination of both. The Risk Assessment will include a detailed report that identifies potential LBP "hazards"; controls (repair/replacement) associated with those "hazards", and provide monitoring recommendations when appropriate. In particular, the Risk Assessment is designed to identify LBP "hazards" that include:

• Deteriorated LBP (chipped, flaking, cracking, chalking, etc.),

• LBP contaminated dust, soil and

• LBP involving accessible (to children), friction (rubbing), or impact

(slamming) surfaces that may have already, or may, in the future, damage a lead painted surface.

During the Risk Assessment, if any painted surfaces are noted to be damaged, then those surfaces are tested for lead content. Dust assays are taken at "key" locations that follow airflow patterns within the home in order to determine if lead is, or has migrated into or within the home.

independent Special Safety evaluations, inc. page: 5 of 17

September 11 , 2000

3. Lead-Based Paint Ratings-iS2e, inc. uses a four scale paint rating system as follows:

• Good-Paint that is "new" or still has much of its "life" remaining. This rating requires no action by homeowner.

• Fair-Paint that is within 6-12 months of failure based on your iS2e, inc.

Risk Assessor's estimate. Paint requires little more than cleaning the surface prior to repainting. Homeowner may save considerable expense by applying another stabilizing coat of paint during the next 6-12 months.

• Poor-Paint that is "cracked or damaged such that its water tight integrity is compromised. Paint and/or substrate may require some repair prior to repainting.

• Unsatisfactory (Unsat)-Paint that is peeling such that the substrate beneath the paint is visible. Paint and/or substrate will usually require some repair prior to repainting. Homeowner· may expect some wood component replacement due to "dry-rot", or metal component repair due to "rust".

B. Standards:

1. HUD/EPA's Lead-Based Paint Standard-defines LBP as ;:::1.0 mg/cm2 (or 0.5% by weight).

2. Lead-Based Paint Hazard-is, by HUD/EPA Standard:

• ~2ft2, interior LBP rated "poor" or "unsat" by your iS2e, inc. Risk

Assessor.

• ~10ft2, exterior LBP rated "poor" or "unsat" by your iS2e, inc. Risk

Assessor.

(Note: HUD's 1012/1013 Regulation will increase the affected area to 20fe effective 15 September 2000.)

3. Lead-Based Paint Dust Hazard-is, by HUD/EPA Standard, ("swipe") dust assay values determined by laboratory testing:

• Floors (hard surfaced and carpetedp-100 Ilg/ft2 (Note: carpeted floors will probably be changed to an "area of concern", vice a limit, with EPA's TASCA 403 Regulation, when finalized.)

• Interior window sill~500 Ilg/fe

• Window troughs (or wells) --2:800 Ilg/ft2

4. Lead Contaminated Bare Soil Hazard-is, by HUD/EPA Standard:

• Bare SoH-~400 ppm, for concentrated children's play areas (e.g. fenced back yards, schoolyards, playgrounds, ball fields, etc.) and vegetable gardens, requiring interim controls or abatement.

(Note: this limit will probably be changed to an "area of concern", vice a limit, with EPA's TASCA 403 Regulation, when finalized.)

• Bare Soi~2000 ppm, for all other residential bare soils, requiring interim controls or abatement.

• Bare Soi~5000 ppm, requires abatement.

independent Special Safety evaluations, inc. page: 6 of 17

5. OSHA Standard-is any level of airborne lead. The "action level" is 30 I-Ig (micrograms) per M3 (meter of air cubed) over an 8 hour, time-weighted-average (twa). This level will drive personnel protective equipment (PPE), such as respirators, coveralls, shower facilities, etc. The OSHA PEL (permissible elevation level) is 50 I-Ig/M3 (twa). This level will add medical monitoring, increased respirator capability, etc. OSHA is concerned with airborne lead and its effect upon the renovation/abatement worker. When LBP surfaces will be disturbed during renovation, especially in small interior spaces (closets, small bathrooms, etc.), the contractor should have the space monitored with a testing device that will alarm when the "action level" is triggered.

OSHA has identified several activities (e.g. manual demolition, manual scraping, manual/power sanding, heat gun applications, general cleanup, power tool cleaning with dust collection systems, and spray painting) that pose varying levels of potential lead exposure to workers disturbing lead-containing paint.

Estimated exposure levels of lead are founded in the activity itself, rather than the concentrations of lead present in the paint. For example, paints that contain 0.5% versus 15% of lead by weight or 0.8 mg/cm2 versus 3.5 mg/cm2 of lead in paint could present the same levels of potential exposure to workers.

In other words, while HUO/EPA define LBP as paint containing 'lead at concentrations ~1.0 mg/cm2

, the OSHA Standard for airborne lead dust anticipates that as little as 0.1 or. 0.2 mg/cm2 of lead in paint could present a hazardous condition when disturbed, causing exposure for workers. Because of this, iS2e, inc. provides the owner with a table (Part IV, A) showing all of the components that contain LBP by the HUD/EPA Standard; and a table (Part IV, B) showin~ all of the components that contain any lead between 0.1 and 0.9 mg/cm.

independent Special Safety evaluations, inc. page: 7 of 17

Part III: Lead-Based Paint Inspection by XRF

September 11, 2000

The EDAX (dba SCITEC), Inc., MAP 4 Spectrum Analyzer (XRF serial number M4-1375) used for this survey irradiates the paint on a given surface causing the lead in the paint, if present, to emit a characteristic frequency of X-ray radiation. The instrument identifies and counts these x rays to determine a lead concentration, and reports this concentration in mg/cm2

The XRF's (X-ray Fluorescence) source used to excite the lead is a 12-millicurie Cobalt57 gamma radiation pellet housed and shielded within the instrument. This particular XRF underwent its annual resource and re-calibration by the factory in Kennewick, WA in October 1999.

The XRF provides readings of "K-shell" (high energy) and "L-shell (low energy) lead. The K shell is the value that determines the amount of lead in the paint. The L-shell gives the operator information on the depth of the lead painted surface.

Your iS2e Risk Assessor uses either the "Confirm" or the "Unlimited" Modes of XRF operation during any Paint Inspections (PI) or Risk Assessments (RA). These modes are the most accurate and time consuming of the four modes (Screen, Test, Confirm, and Unlimited) within the instrument. The operator holds the trigger when sampling using the Unlimited Mode, until he/she gains approximate 2cr (sigma) worth of data on any given surface. This provides approximately 95% accuracy. The instrument is calibrated 5 times and averaged prior to leaving the office, calibrated at the job site, and re-calibrated approximately every hour thereafter, including job completion.

As can be seen from the Daily Calibration Log, an appendix to this report, M4-1375 remains within 0.10 mg/cm2 of the required 1.39mg/cm2 factory calibration block.

The SCITEC Ma~ 4 XRF has an "inconclusive" software" signal built into the instrument from

0.9 to 1.2 mg/cm . Values below this amount are, by HUD/EPA Standard, not lead-based paint (LBP). Values above this range are clearly LBP. The operator can take a paint chip sample for laboratory analysis in order to prove the accuracy of the reading when the reading is in this "inconclusive range", or make a conservative determination that the "inclusive" value contains

LBP.

Because the XRF has a capabilit¥ (calibration accuracy) of ±0.1 mg/cm2 when operating in the Confirm and Unlimited modes, is e, inc. has chosen to consider all readings (values) equal to or above 0.9 mg/cm2 to contain LBP. This corporate decision is based on 5 years of RA and PI experience. This determination saves the homeowner the laboratory analysis cost of multiple paint-chip samples, and does not adversely mark or harm any painted surface on the property (e.g. banister, windowsill, baseboard, door or window trim, etc.), often requiring expensive/time consuming repair.

When reading the XRF Preliminary Report, an addendum to this report, all negative K and L shell values should be interpreted as "zero". All K-shell XRF values above 0.1, but less than

0.9 mg/cm2 contain some lead, but the lead content is below the HUD/EPA standard defining LBP. All values at or above 0.9 mg/cm2 are considered, by iS2e, inc., to be LBP.

independent Special Safety evaluations, inc. page: 8 of 17

The SCITEC Map 4 XRF has, built into the software, substrate correction values that prevent the operator from having to make the corrections manually. The "Unlimited" mode of operation will correct properly, even if the operator makes an incorrect coding error (e.g. setting sheetrock when the substrate is actually plaster, etc.).

The 12-millicurie Cobalt57 gamma radiation pellet is so weak, even when first delivered from the factory, that it will not cause ionizing radiation to any surface or component tested. In other words, once the XRF is removed from the home, there is no lingering radiation, or any evidence that the XRF has ever been there.

Reading the Reports contained in the Appendices

1. Raw XRF Data:

Includes the coded address for the site, calibration data (both daily, and site beginning and ending), as well as assay data that has been collected at the home, apartment or day-care center.

2. Preliminary XRF:

Gives K & L-Shell XRF readings in mg/cm2

• The federal "action-level", always taken against the K-shell, is 1.0 mg/cm2

. The XRF has an "inconclusive" range of -0.1 to +0.2 centered about the "action-level". Should this "inconclusive" value occur, your Risk Assessor could remove a small (approx. 2x2 inch) sample of the painted surface for laboratory analysis, or declare the component to contain LBP. Declaring a component that contains 0.90 mg/cm2 to contain LBP is a conservative and cost effective method of evaluating LBP.

Room # refers to the number of "like" rooms (e.g. 3 bedrooms). Wall # is conventional, where wall #1 is the wall toward the street (front or address side of the dwelling), and the other walls are numbered clockwise. Wall #3 is away from the street. Type refers to the mode of analysis that the SCITEC MAP 4 is operating under (e.g. screen, test, confirm, and unlimited). iS2e, inc. uses the confirm and unlimited modes exclusively, carrying the analysis to 20' (95% confidence level) in accordance with EPA and HUD standards.

Numerous interior, wooden, concrete, tile, and sheetrock/plaster dwelling components are checked. These include, but are not limited to, exterior walls, wood trim, window trim and frames, door trim, frames and jambs, roof trim and soffit, interior walls, hard surface flooring, including tile floors, baseboard, tub and shower surrounds, counter tops and back splashes, cabinets, windowsills, doors, and door jambs, etc.

3. Daily Calibration:

Includes the Daily start calibrations (normally 5) with times, and includes the site "start" and "stop" calibrations, as well as any others taken against a known "assay block" provided to iS2e, inc. by the SCITEC Corporation. The MAP 4 must always remain within ±0.1 of the factory test calibration for that specific serial numbered MAP. It will also typically remain within ±0.1 of the five Daily averages (column 6).

XRF MAP IV, serial number M4-1375 has had an exceptional record for accuracy. It almost always calibrates at or very near the 1.39 mg/cm2 certified SCITEC assay block, even early in the workday and increases its accuracy as the device warms.

independent Special Safety evaluations, inc. page: 9 of 17

This XRF device was resourced and delivered by FEDEX from the SCITEC factory in Kennewick, WA, 1000, 10-19-99.

4. HUD Single Family Housing Report:

This report is included for Paint Inspections (PI) because the HUD Guidelines requires that Pis test interior and exterior walls four times (all four walls within each room group or equivalent). Additionally, this report contains current surface paint color, where the Preliminary XRF Report does not.

5. Assaigai Laboratory Report:

Dust-The report gives "swipe" assay results in Ilg/ft2. The dust assay values give the iS2e Risk Assessor a valid method for determining whether any lead-based paint has deteriorated to a level that may have already, or will in the future, contribute to the contamination of the dwelling, and whether that dust, if contaminated, has migrated within the dwelling.

Bare Soil-The report gives soil sample values in PPM (parts per million or Ilg/g).

Dripline soil is that soil within 3-4 feet of the foundation of the home or apartment. It is often contaminated to a greater extent than yard soil, especially for older dwellings that contain significant exterior LBP. Yard soil is normally selected from areas that have evidence of the presence of children, or from vegetable gardens.

6. Lead-Based Paint-The "do's" and 'don'ts" of LBP repair:

When painted dwelling components contain LBP above the federal "action-levels";

DO NOT allow repairs to include:

a) Dry scraping or sanding, including machines without proper vacuum collection capability

b) Unconfined hydra-blasting

c) Open-flame burning or torching

d) Abrasive blasting or sand blasting without using HEPA vacuum exhaust tools

e) Heat-guns that operate above 1100°F

f) HUD does not recommend using methylene chloride chemical strippers

When painted areas contain LBP above the federal "action-levels"; DO require repairs to include:

a) Use of HEPA filtering equipment attached to the sanding machines

b) Use of HEPA filtering vacuums to clean-up the area that has been scraped or sanded

c) Containment of the affected areas (e.g. no high winds)

d) If doors (exterior or interior) are removed to repair jambs, then seal off the residence of affected area using plastiC sheeting and tape. (e.g. if repairing

e) a jamb on an exterior door leading to the kitchen, hang plastic sheeting with a ''full-seal'' tape on the inside of the door to prevent the LBP dust from migrating into the kitchen.)

f) Disposal of any contaminants and contaminated components using proper disposal methods.

independent Special Safety evaluations, inc. page: 10 of 17

7. Non-Professional Repair of LBP Components:

September 11 , 2000

It is not often legal to repair, abate, or apply interim controls to LBP "hazards" or painted components that contain LBP to rental dwellings, or homes that house members not of your immediate family, unless you are trained to do so. However, it is permissible to make repairs when following (exactly) the written instructions of a certified LBP Risk Assessor. Those items that you can accomplish personally, involve:

• planting sod or placing other ground covering such as rock, over bare soil,

• painting surfaces that have been prepared professionally, or

• removing components that will not disturb LBP, such as doors, and then having them disposed of properly if they contain LBP.

8. Risk Assessments versus Paint Inspections:

Please remember a Risk Assessment does not test or identify all painted surfaces.

It only identifies those painted surfaces that were unsound (rated "poor" or "unsat" by your is2e Risk Assessor) unless specifically noted otherwise in the reports. A Paint Inspection, however, tests all "like" painted surfaces. "Like" painted surfaces are those that your iS2e Risk Assessor or Paint Inspector estimates to have the same or similar paint history, and clearly contain pre-1978 paint.

9. Title X's Disclosure Requirements:

A copy of this report must be provided to new lessees (tenants), providing the lease exceeds 100 days, and to purchasers of this property under Federal law (24 CFR part 35 and 40 CFR part 745) before they become obligated under a lease or sales contract. The complete report must also be provided to new purchasers and it must be made available to new tenants.

Landlords (lessors) and sellers are also required to distribute an educational pamphlet approved by the U.S. Environmental Protection Agency and include standard warning language in their leases or sales contracts to ensure that parents have the information they need to protect their children from lead-based paint hazards.

Any repairs specified by this report, or accomplished on any of the leaded (Pb) surfaces identified in this report (See Table in Part IV, Sub-part A) should be documented on this report, attaching receipts to the report, maintaining dates, and any notes directly on the report. This report should be preserved and maintained with this dwelling. It will serve present and future homeowners with proper lead (Pb) disclosure as required by Title X, Section 1018 of Public Law 102-550.

10. Contacting your iS2e Risk Assessor:

If owner or agent has any questions concerning the findings or ramifications of this report, please call your iS2e Risk Assessor at 823 6411 (Albuquerque), or 1 888 828 0607 outside of Albuquerque.

The HUD Guidelines require that painted interior walls of each room must be tested during a paint inspection. The requirement is driven by the fact that the interior walls generally contain the greatest painted areas within the home, and the fact that the lead content of the paint seldom is applied/distributed evenly.

independent Special Safety evaluations, inc. page: 12 of 17

Most of the exterior white paint on this home on the wood surfaces is in "poor" or "unsatisfactory" condition and in need of repainting. Most of the exterior white paint on the concrete block walls is in "fair" condition, and also should be repainted sooner rather than later.

Most of the interior paint in this home is rated to be in "good" condition. The amount of lead and concentrations in the interior of this home is indicative of 1950s or early 1960s interior paint.

C. Non-lead-Containing Components-Those items that contain lead below 0.1 mg/cm2

, or contain a negative K-shell reading.

All other components checked by XRF, throughout the property, and not listed in either of the two tables above, contained no detectable (or insignificant) lead content.

D. Paint Ratings-while regulations do not allow paint condition ratings by a paint inspector; the regulations do allow such rating during a paint inspection when performed by a risk assessor. This is done to assist the renovation contractor by alerting him/her to those painted surfaces that may require attention.

• Paints rated "Good" that contain lead present no current hazard unless disturbed.

• Paints rated "Fair" are nearing the end of their useful life and should be re stabilized with another coat of paint before they can become a source of lead dust.

• Paints rated "Poor" (cracked) or "Unsatisfactory" (peeling). should be removed, the surfaces/substrates repaired/replaced and then re-painted. The lead paint removal process should involve capturing all of the leaded paint, not allowing it to contaminate soil or any interior surfaces.

independent Special Safety evaluations, inc. page: 13 of 17

Part V: Lead-Glazes in Ceramic Tiles

September 11, 2000

NOT A LEAD HAZARD-The ceramic tiles on the Utility Room floor and Full Bathtub surround, contain low quantities of lead in their glazes. The ceramic tile on the Living Room Hearth, however, contains significant lead in the glazing. (The reader's attention is invited to see lines 452, 467, and 472, column #9 of the Preliminary XRF Report).

The interim federal standard, identifying lead-based paint, contains 1.0 mg/cm2 of lead. These ceramic tiles contain lead between 0.279 and 6.020 mg/cm2

However, it is your iS2e Risk Assessor's opinion, in consultation with the Region VI EPA toxic waste coordinator, Mr. Jeff Robinson, that these tiles currently do not present any LBP "hazard".

During renovation, if these tiles are removed/replaced (broken-up), they can create a significant amount of lead dust. Precautions should be taken during any such evolution to protect the workers, the inhabitants, and the dwelling itself. During any future renovation (when Pb painted surfaces, including the ceramic tiles, may be disturbed), Pb levels, even very low ones, can exceed OSHA respiratory Permissive Elevation (breathing) Levels (PELs), especially in confined spaces (e.g. closets, small bathrooms, etc.).

Ceramic tile has a baked-on glaze that is sufficiently durable to capture and hold any Lead Paint/glazing, so long as the glaze remains intact. The homeowner may limit his/her liability by making this report available to any contractor that attempts to remove this tile. This will alert the contractor to follow the OSHA regulations with regard to PELs. Additionally, the contractor should take ample precautions to prevent the spreading of any Pb dust during the tile removal throughout the home. These precautions should include:

• Sealing the affected rooms, using plastic sheeting and masking tape;

• Removing the tiles;

• Gathering the tiles into plastic bag-lined cardboard boxes (where the bag can be closed prior to removal from the area); and

• USing HEPA filtered vacuums (going over all exposed surfaces in the affected areas, including ceilings, walls, floors, windows, frames, sills, door trim, baseboards, etc.), twice covering with the vacuum all areas of the affected rooms, prior to unsealing those rooms.

In order to repair any chipped or damaged tiles in the future, these should first by washed with warm, soapy water, rinsed and dried. The homeowner using epoxy-resin-paint may then repair the damaged portion of the tile. This will re-seal the lead within the glaze.

These leaded tiles should only be cleaned with pH neutral or basic solutions (soaps, aqueous bleach, or common cleaners - e.g. 409, etc.) Acid solutions, even mild ones, may eventually attack the glaze in these tiles, and therefore should not be used. Even vinegar and water, if used enough times, may break down the glaze protecting the lead in these tiles, and therefore, should not be used.

WARNING

DO NOT MIX AMMONIA AND BLEACH.

This combination will form a deadly gas!

Lead-Based Paint Risk Assessment

A. Visual Inspection/Findings:

iS2e, inc. conducted a Lead-Based Paint (LBP) Inspection (PI) and LBP Risk Assessment (RA) at Quarters No. 66, Inks Dam National Fish Hatchery, Burnet, TX 78611 on August 30,2000. The home was occupied at the time of this inspection.

Quarters No.66 is a single story, pitched-roofed, frame and concrete block, single family home with 3 bedrooms. The home faces to the east. Original construction occurred in 1957, comprising approximately 1182 ft2. The home presently houses a single, adult, male, full-time NFH employee.

Floor dust samples were gathered from the front entry and back porch entry to this home. Windowsill dust samples were gathered from Living Room (N), Bedroom #1

(S) and Bedroom #2 (W).

A composite soil sample was gathered from various points, near the foundation, beneath windows, and annotated on the sketch at the end of this report. The bare soil, composite yard samples concentrated on play areas on the east and west sides of this home.

The results of the dust and soil testing are discussed in Sections 0 and E of this Part.

B. Background/Use Information: The home functions presently as a permanent residence for a single, adult, male full-time NFH employee.

c. Lead-Based Paint Hazard{s) Identified: ONE (1)

1. The exterior white paint on the overhead garage door was rated to be in "unsatisfactory" condition, and contains more than 10ft2 of LBP. Based on the age and condition of the door, it will be cost effective to replace the door. The Garage Doorjambs should be chemically stripped and repainted. Comments in Part IV, Para. B, concerning exterior white paint are germane, but do not represent a lead "hazard".

D. Lead Dust Hazard(s) Identified: NONE (0)

The Assaigai Analytical Laboratories single floor dust assay values for:

• The front entry ....................................... ND Ilg/fe

• The rear entry to Back Porch ................. 6.8 1l9/ft2

NO = no lead detected. These values are significantly below the federal Risk Assessment (RA) "action-level" (100 Ilg/fe). The Back Porch value is reflective of the condition and lead content of the white paint peeling on the exterior wood surfaces near the entry door. The Laboratory's detection limit for this sample is 5 Ilg/fe .

independent Special Safety evaluations, inc. page: 15 of 17

The Assaigai Analytical Laboratories single windowsill dust assay values for:

• Bedroom #1 ........................................... NO /-lg/ft

2 • Bedroom #2 ........................................... NO /-lg/ft

• Dining Room .......................................... NO /-lg/ft2

Each of these values is below the federal Risk Assessment (RA) "action-level" (500 /-lg/ft\ The Laboratory's detection limit for these samples is 13.6, 12.4, and 14.4 /-lg/ft2 respectively. These extremely low values are reflective of the post WWII paint and a lack of plastic mini-blinds.

With reasonable exterior paint maintenance, and absent any leaded mini-blinds, it has been your iS2e Risk Assessor's experience to find that maintaining windowsill dust lead levels at 10 /-lg/ft2 or less with quarterly cleaning is quite possible. '

E. Lead Contaminated Soil Hazard(s) Identified: NONE (0)

The Assaigai Analytical Laboratories composite bare soil assay values for:

• The dripline ................................................. 91.5 PPM

• The play yard area ...................................... 5.4 PPM

Both of these values are below the lowest federal Risk Assessment (RA) "action level" (400 PPM for high-density children's play area). However, the dripline lead contamination is most certainly reflective of the condition and lead content in the white exterior trim paint on wood surfaces. The Laboratory's detection limit for these samples is 5 PPM.

iS2e, inc. routinely finds most soils in residential settings throughout the State fall in the 10-25 PPM range.

F. Lead Water Hazard(s) Identified: NONE (0)

The Assaigai Analytical Laboratories water testing assay value for:

• The Kitchen Sink - "1 st Draw" ..................... 3.0 /-lg/L

The US EPA Standard for "1 st Draw" water testing is to take place at the kitchen sink, and be the first water from the tap that day. This is to allow time (over night) for the lead (if any) to leach from the water pipes, solder joints, or metal into the drinking/cooking water. The Standard is 15 /-lg/L (millionths of a gram of lead per Liter of water). The test value is unremarkable.

G. Other Lead Hazard(s): NONE (0) independent Special Safety evaluations, inc. page: 16 of 17

Prioritized List of Lead Hazards Identified

C. Recommended Solutions for Lead Hazards Identified:

2. Exterior Lead Paint Hazard #1:

b. The exterior white paint on the overhead garage door was rated to be in "unsatisfactory" condition, and contains more than 10fe of LBP. Based on the age and condition of the door, it will be cost effective to replace the door.

The LBP on the Garage doorjambs should be chemically stripped and the jambs then primed and repainted.

D. Estimated Costs to Repair Lead Hazards Identified:

2. Repair of Jambs and Replacement Cost for the Garage Door-Hazard #1:

b. Cost estimate to replace the Garage Door is $600.00. Cost estimate to repair the Garage doorjambs is $200.
