(a) SSPCSociety for Protective Coatings Level 1 Visible Emissions. The following Level 1 visible emissions criteria apply when any paint is disturbed by dry methods such as blast cleaning or power tool cleaning.
Level 1 Emissions are defined as random visible emissions of a cumulative duration of no more than 1 percent of the workday or approximately five minutes in an eight-hour day. Level 1 is required for all structures. The ContractorAny person having a Contract with a procurement agency. Contractor does not include an employee with an employment Contract, or an employee organization with a collective bargaining agreement.’s QC person, or Competent PersonAny individual or a corporation, partnership, sole proprietorship, joint stock company, joint venture, unincorporated association, union, committee, club, or other organization or legal entity. in the case of toxic metals projects, shall perform at least two 15 minute documented observations during each work shift. In addition to the 15-minute observations, all ContractorAny person having a Contract with a procurement agency. Contractor does not include an employee with an employment Contract, or an employee organization with a collective bargaining agreement. personnel shall be directed to routinely observe the work area and to report unacceptable emissions to QC or supervisory personnel, or to the Competent PersonAny individual or a corporation, partnership, sole proprietorship, joint stock company, joint venture, unincorporated association, union, committee, club, or other organization or legal entity..

Retain the records on site, and make them available to the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him..
The visible emissions criteria are not required when the paint is cleaned or disturbed using water. When water is used on existing coatings that contain toxic metals or on inorganic zinc/vinyl systems, all water shall be collected and emissions are prohibited. When water is used to clean all other coating systems, the water need not be collected and emissions are not restricted.
(b) Ambient Air Monitoring. Unless otherwise directed, ambient air monitoring is required when the coatings being disturbed contain toxic metals, and whenever the paint removal operations are located within 500 ft of houses, schools, parks, playgrounds, shopping areas, or similar areas of public exposure.
(1) Abrasive Blast Cleaning. Daily ambient air monitoring at each structure being abrasive blast cleaned shall begin one day prior to beginning work and during the first 10 days of productive abrasive blast cleaning operations. When the results indicate that the containment is controlling emissions, full time monitoring may be discontinued unless otherwise directed. However, monitoring shall be repeated for two consecutive days every month thereafter during the work shift while blast cleaning or other dust producing operations are underway.
When the results of the original 10 days of monitoring or the periodic monthly tests are unacceptable, monitoring shall continue full time. Monthly monitoring may be initiated or resumed only when approved, and only after the results of the testing indicates that the containment is controlling emissions.
Full time monitoring shall also be resumed when unacceptable visible emissions or residues are observed on the ground or water.
(2) Hand and Power Tool Cleaning. Begin daily ambient air monitoring at each structure one day prior to beginning work and during the first five days of hand tool cleaning and power tool cleaning. When the results indicate that the containment is controlling emissions, full time monitoring may be discontinued, unless otherwise directed. Resume monitoring when visible residues are observed on the ground or in the water, or visible dust is observed exceeding the Visible Emissions criteria established above.
(3) Monitor Placement and Reporting. Place total suspended particulate (TSP) monitors in areas of potential public exposure (e.g., adjacent to homes, businesses, parks, or pedestrian walkways) that are within 500 ft of each project site during cleaning operations in conformance with Method D of SSPCSociety for Protective Coatings Guide 6. The CIH shall provide for EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him. acceptance, the proposed monitoring locations in advance, together with the rationale for the selection of each site.
