b. Avoid high-dust jobs and procedures.

c. Plan how the component will be removed.

December 23, 2025 ■ Terracon Project No. 9025P137

2. Remove component

a. Score all painted seams with a sharp knife

b. Remove or Bend Back Fasteners

c. Remove screws, nails, staples, etc. as necessary with hand tools

d. Include any affected hardware to be stripped of LBP

3. Use of off-site stripping facilities

a. Wrap and seal bulk components in poly and take to a secured waste storage area along pathways covered in plastic.

b. Tag the component with identifying information that will direct its eventual reinstallation at its original location.

c. If a 3rd party paint stripping entity is performing stripping work, inform them that the components are LBP affected.

4. When chemically removing LBP on-site, the contractor shall:

a. Utilize Enviro Klean® Safety Peel 1 and OverCoat chemical stripping agents, or an approved equal, in accordance with the recommendations of the manufacturer.

b. Final Cleaning of Surfaces: Prepare wet detergent wash.

Workers must wear eye shields and chemically resistant gloves when working with this solution. Thoroughly scrub stripped surface to remove as much remaining lead residue as possible. Following wet detergent wash, perform a final wash with clear water to remove any traces of detergent. Sponges used in the clean-up process may not be reused and must be placed in double 4 mil or single 6 mil plastic bags, which will be sealed, labeled, and placed in the secure waste storage area.

Surfaces must be allowed to dry thoroughly before repainting.

c. Painting/sealing: After complete drying, prepare the substrate and seal all surfaces where lead-based paint was removed with a primer or encapsulant which is compatible with the substrate or as specified by the Owner and/or Architect.

December 23, 2025 ■ Terracon Project No. 9025P137

5. If the specified methods above are not feasible, the following shall apply:

a. Any Chemical Stripping Agents and neutralizers shall be applied in accordance with the recommendations of the manufacturer.

b. Caustic Stripper Neutralization: Caustic strippers shall be neutralized in accordance with manufacturer's recommendations. Provide workers with proper protective equipment, including but not limited to;

protective clothing (non-paper), chemically resistant gloves, eye protection and respiratory protection with filters selected for the hazards to be encountered.

c. Remove Stripper Sludge: Place lead containing stripper sludge in corrosion-proof containers and place in a secure waste storage area. The surface from which lead-based paint has been removed shall be thoroughly scrubbed, while still damp from the stripper, in accordance with the manufacturer's recommendation.

Monitor pH of the neutralizing solution to ensure it has not become neutralized in the process.

d. If the pH exceeds 6.5, or the solution becomes overly soiled, change solution. The surface shall be tested with litmus paper following this process. If the litmus paper turns pink, the acid has effectively neutralized the alkali.

If litmus turns blue continue scrubbing until satisfactory results are achieved.

e. Final Cleaning of Surfaces: Prepare wet detergent wash.

Workers must wear eye shields and chemically resistant gloves when working with this solution. Thoroughly scrub stripped surface to remove as much remaining lead residue as possible. Following wet detergent wash, perform a final wash with clear water to remove any traces of detergent. Sponges used in the clean-up process may not be reused and must be placed in double 4 mil or single 6 mil plastic bags, which will be sealed, labeled, and placed in the secure waste storage area.

Surfaces must be allowed to dry thoroughly before repainting. A grayish film indicates that significant lead residues remain and the cleaning process must be repeated. If a white powder appears, the surface is Alkaline and requires further neutralization.

December 23, 2025 ■ Terracon Project No. 9025P137

f. Painting/sealing: After complete drying, prepare the substrate and seal all surfaces where lead-based paint was removed with a primer or encapsulant which is compatible with the substrate or as specified by the Owner.

6. Painting/sealing: After complete drying, prepare the substrate and seal all surfaces where lead-based paint was removed with a primer or encapsulant which is compatible with the substrate or as specified by the Owner.

B. See note in Section 2.2 General for further information on asbestos-containing materials located adjacent to components scheduled for impact as part of the scope of work.

PROJECT DECONTAMINATION

General

A. Final Cleaning:

1. HEPA Vacuum: All surfaces in work area. Start at point farthest from main entrance and finish vacuuming back at that point. Begin at top of each room and work down.

Sequence to avoid passing through rooms already cleaned.

2. Mist critical barriers sheeting and remove.

3. HEPA vacuum area previously covered by critical barrier sheeting.

4. Perform wet detergent wash of all surfaces. Begin at point farthest from main entrance, work from top to bottom. Take care not to damage existing finishes and surfaces. Change cleaning mixture in accordance with manufacturer's recommendations or minimum after each room.

5. Wiping Work Area

a. The work area should be cleaned using a three-container method. Fill two buckets with clean water and place them in the work area with the container of cleaning solution.

b. Pour cleaning solution onto a clean cloth. Wring excess solution into one of the buckets without placing the cloth into the bucket. Wipe the work surface with the cloth. Add more cleaning solution to the cloth and continue wiping until the entire surface area has been covered. Discard all cloths used in this procedure in the disposal bag.

c. Dip and wring out a clean cloth in the first rinse bucket. Wipe off the work area. Rinse the cloth in the first bucket again and wring out thoroughly. Rinse the cloth in the second bucket and wring out thoroughly again.

December 23, 2025 ■ Terracon Project No. 9025P137

d. Continue to clean the work surface with the cloth and rinse using this procedure until the entire work surface has been cleaned. Wipe off all tools to remove any dust.

e. NOTE: The rinse water in the bucket should be changed periodically. The frequency will vary depending on the level of contamination.

6. Perform clear water wash of all surfaces in same manner as wet detergent wash.

7. After all surfaces in work area are allowed to dry, complete final HEPA vacuuming of all surfaces in same manner as first HEPA vacuuming.

8. After final cleaning perform a complete visual inspection of the entire work area including: all surfaces, ceiling, walls, floor, doorways, windows, surfaces previously covered with critical barrier sheeting, and other openings; look for debris from any source, residue on surfaces, dust or other matter. If any debris, residue, dust or other matter is found repeat final cleaning and continue decontamination procedure from that point. When the area is visually clean, complete the certification at the end of this section. Visual inspection is not complete until confirmed in writing, on the certification, by Project Monitor.

WORK AREA CLEARANCE

General

Notification and scheduling of the final inspection during the project is the responsibility of the Contractor. If abatement was performed, the contractor shall notify the regulating entity 24 hours before the project’s completion. It is recommended that the contractor assumes the potential of an initial failure of clearance sampling into the projected schedule. Additional cleaning, sample re-collection, and sample re-analysis should be considered prior to build-back activities and re-occupation of residents.

Contractor shall coordinate all LBP activities including lead work, clearances, potential re-cleaning, re-testing, build back, and re-occupation of residents with the Owner and Project Monitor. Use of areas within identified units by occupants shall be determined by the Owner.

Clearance

A. No sooner than one hour after the final cleaning and after the work area is completely dry, the following test procedure shall be performed:

1. A final visual inspection shall be conducted by the Project Monitor who is also an EPA and Texas certified lead-based paint inspector/risk assessor (i.e., clearance examiner). When applicable, an interior clearance area should have no evidence of settled dust or paint chips or paint-related debris following a cleanup effort. If dust, paint chips, or paint-related debris are observed, the Contractor will be required to reclean the work area(s) at their expense.

December 23, 2025 ■ Terracon Project No. 9025P137

2. Once the visual inspection has passed, clearance dust sampling shall be performed for interior work areas in accordance with EPA and Texas regulations. Samples should be collected in accordance with Appendix 13.1 and Chapter 15 of the HUD Guidelines and ASTM E 1728.

3. Clearance wipe samples must be analyzed for lead by a laboratory recognized by the EPA under the National Lead Laboratory Accreditation Program (NLLAP) for analysis of lead in dust.

4. Composite sampling is not allowed for clearance dust wipe samples.

5. Wipe samples should be collected after any application of a sealant on a rough, unfinished, horizontal surface, such as a floor or windowsill, not before.

6. Compare the laboratory results to the EPA's Final Rule, issued on November 12, 2024, effective January 13, 2025, with compliance after January 12, 2026 clearance standards for residual lead dust provided below:

Lead Hazards: Any Reportable Level Clearance (Floors): 5 micrograms per square foot (µg/ft2) Clearance (Interior windowsills): 40 µg/ft2 Clearance (Window troughs): 100 µg/ft2

7. Where applicable, the project monitor shall ensure that the work has been properly completed and that no deteriorated paint identified as part of the scope of work remains in the work area(s).

8. Where exterior interim control measures are performed: Exterior clearance following exterior paint work consists of a visual assessment for visible surface dust, debris and residue.

9. Where exterior abatement is performed: Soil and exterior dust sampling is required. Sampling shall consist of at least one sample taken from an adjacent exterior horizontal surface including, but not limited to, a patio, deck, porch, stoop, or common area and composite soil samples taken next to the foundation or from the dripline and any applicable bare soil areas adjacent to the exterior abatement that children, age 6 years and under, frequent. Clearance soil lead concentrations will be required to be less than 1,200 ppm in non-play areas and less than 400 ppm in play areas.

10. The Project Monitor shall immediately report the final clearance dust wipe sampling results to the Project Designer. Clearance results will be provided within 24 hours following receipt by the analytical laboratory.

December 23, 2025 ■ Terracon Project No. 9025P137

11. If clearance dust sampling fails, the work areas will need to be re-cleaned and re-tested at the Contractor’s expense.

It is recommended that the contractor assumes the potential of an initial failure of clearance sampling into the projected schedule. Additional cleaning, sample re-collection, and sample re-analysis should be considered prior to build-back activities and re-occupation of residents.

DISPOSAL OF WASTE MATERIAL

General

A. Per EPA, waste generated as part of LBP activities conducted at residences (which include single family homes, apartment buildings, public housing, and military barracks) is also household waste, and such wastes are excluded from RCRA’s hazardous waste management and disposal regulations. Generators of residential LBP waste do not have to make a RCRA hazardous waste determination.

B. Large waste material should be wrapped in heavy-duty sheeting (6-mil polyethylene or equivalent), and all seams should be sealed with tape during storage and transported to the appropriate landfill.

C. Small waste material (including lead-contaminated protective clothing) should be placed in heavy-duty bags (double 6-mil or 4-mil polyethylene or equivalent). The bags should be securely taped shut with gooseneck closure.

D. The waste should be stored in a designated secure (locked) area. Dumpsters should have lids and be padlocked.

E. An enclosed dumpster will be used to haul waste material to the disposal site. No rental vehicles or trailers shall be used. Vehicle selection, vehicle covers, and work practices shall assure that no lead is dispersed into the environment during the loading, transport and unloading activity, and that material is placed in the waste site without breaking any seals.

F. The Contractor shall transport the bags of waste material to the appropriate landfill.

The sealed plastic bags shall be placed into the burial site unless the bags have been broken or damaged.
