Boulder Cottage #5 Project 02065- 5 of 8 July 2024 all other applicable federal, state, county or local regulations and guidelines. It shall be the sole responsibility of the Contractor to assure complete compliance with the more stringent of all laws and regulations relating to any and all hazardous and nonhazardous waste storage, handling, security, and disposal. Until hazardous waste characterization analytical results are available, all waste materials (including water) shall be handled, stored, and secured as hazardous wastes, and stored separately from all other wastes. All wastes shall be separated and segregated into appropriate waste streams.

B. Prior to the start of work, the Contractor must coordinate disposal with an approved disposal facility.

C. During or after the actual abatement, the Contractor shall not: leave debris in the yard or in near-by property; place debris into an unsecured container; incinerate debris; dump debris at any unauthorized location; place debris in any unauthorized dumpster; transport any waste or debris in non-licensed or permitted vehicles; or introduce lead contaminated (non-filtered) water onto soils, into storm sewers (shall not be poured down yard inlet or street drain) or sanitary sewers (shall not be flushed down toilet or any other household, residential or commercial type drain system).

D. The Contractor shall make all efforts to minimize the amount of hazardous waste produced (through accepted practices of waste separation/segregation, etc.).

Additionally, the Contractor shall seek to identify and use a transport, storage, and disposal (TSD) facility that will incinerate, recycle, or reclaim all wastes rather than having wastes sent to a landfill for whole disposal. All wastewater, clean water, and wash water shall be so labeled. All wastewater shall be labeled "filtered" (using 3-micron filter) or "non-filtered". All non-filtered wastewater containers shall be labeled "hazardous waste" and with a date the Contractor began to collect contaminated water in that container. All filtered water must be hazardous waste characterization tested to confirm that it is or is not hazardous and disposed of accordingly.

E. Testing on lead-based painted abatement items or abatement waste materials shall be completed by the Contractor. Testing shall be performed as soon as representative samples are generated. Representative samples for each waste stream will be taken and analyzed to comply with applicable federal, state, county or local regulations and guidelines.

F. Hazardous waste characterization tests will be paid for by the Contractor if the Contractor has unnecessarily separated waste materials and/or debris, so as to create additional waste streams, or if the Contractor has consolidated waste streams and failed to appropriately and properly segregate and separate waste streams from one another.

G. A representative number of samples of the following materials will be tested to determine whether or not they are hazardous:

1. Wastewater - filtered and non-filtered, including all wash water;

2. Dust from HEPA filters;

Boulder Cottage #5 Project 02065- 6 of 8 July 2024

3. All lead-based painted component/substrate items;

4. Plastic sheets, duct tape, or tape used to cover floors or other services during the lead-based paint abatement;

5. Solvents and caustics used during the abatement process (if any);

6. Rags, sponges, mops, scrapers, HEPA vacuum filters, and other materials used for abatement, and clean-up; and,

7. Any other items contaminated with lead-based paint or items produced as a result of lead-based paint abatement activity.

8. Storage, Inspection and Record Keeping Requirements. Any item found to be hazardous, by way of testing, shall be kept in a secured area and lockable container, that is inaccessible to all persons other than abatement personnel. All hazardous waste shall be labeled "Lead-Based Paint Abatement Hazardous Waste" and the date that the Contractor began to collect waste in that container. All hazardous and non-hazardous waste shall be kept in separate containers. All hazardous waste shall be stored, handled, transported, and disposed of in a manner to meet the more stringent of all federal, state, and local requirements.

The Contractor shall, on at least a weekly basis, inspect all waste containers to ensure that the containers and the container integrity are sound and continue to be appropriate for the wastes stored in the containers. The Contractor shall keep a journal which records the results of all container inspections conducted and includes the dates and times of the inspection, as well as the name of the individual(s) conducting the inspections.

3.05 CONFIRMATION SAMPLING

A. Once all known areas of LBP designated for removal have been removed from the buildings, a confirmation survey will be performed by the Contractor using an XRF field instrument calibrated for the standard detection limits for LBP surveys. Suitable sample locations should have adequate, non-faded, and unchipped paint. The confirmation survey will use field screening using the XRF field instrument to determine if any remaining paint is LBP. Remaining LBP components shall be encapsulated per Specification 02080.

B. If LBP is found during confirmation screening, the sample nomenclature for XRF will be numbered in sequential order as determined by the XRF unit. The results of the XRF survey will be recorded on field sheets or the logbook. Locations, if found, will be noted on floor plans for future locating and removal or encapsulation prior to the building renovation. If conditions warrant nomenclature modification, the change will be documented in the logbook.
