(b) Assessment of Visible Emissions and Releases

1. General
    Conduct visible emissions assessments as defined in this Item, in accordance with 40
      CFR 60, Appendix A, Method 22. These assessments are based on total visible
      emissions regardless of the opacity of the emission. Conduct visual inspections for
      releases or spills of dust and debris that have become deposited on surrounding
      property, structures, equipment or vehicles, and bodies of water.
    Consider all State, City, or County regulations regarding visible emissions in addition
      to, but not in lieu of, the requirements of this Item.
    Include procedures in Environmental Compliance Plan for the assessment of the
      visible emissions and releases, the frequency of observations and inspections that
      will be made, the equipment and work areas (e.g., containment) that will be
      observed for visible emissions, and the surrounding property and structures that will
      be examined for deposited debris.
2. Acceptance Criteria for Visible Emissions Assessments
    Limit random visible emissions from project activities to an SSPC Level 1 (no greater
      than 1% of the workday) in accordance with SSPC Guide 6. Conduct visible emission
      assessments in accordance with 40 CFR 60, Appendix A, Method 22.
    Pennsylvania State Regulation Title 25, Chapter 123.42, Section 123.42 exempts
      construction operations from the opacity requirements established under Section
      123.1. However, it is the Department's policy, through this specification, that all
      bridge projects will comply with the opacity requirements, as established under
      Section 123.1.
    Immediately shut down the emission-producing activities if emissions in excess of the
      criteria stipulated in this Item are observed. Do not resume the emission-producing
      operations until the cause of the violation is corrected.
    Immediately shut down the project and initiate corrective action if there are
      violations of high volume ambient air monitoring, even if the visible emissions results
      are acceptable.
    Clean up releases of dust and debris outside of the work area that have become
      deposited on surrounding property; on the unprotected ground, soil, water or
      sediment; around storm sewers or drains; or in areas where rain water could carry
      the debris into storm sewers or drains. Conduct the clean up on a daily basis, or
      more frequently if directed by the Engineer, and take appropriate corrective action to
      change work practices or to modify the containment to provide better controls over
      releases in the future.
3. Frequency and Location of Assessments and Inspections
    Conduct the visible emissions assessments to account for all locations where
      emissions of lead dust might be generated, including but not limited to, the
      containment, dust collection and abrasive recovery equipment, and waste
      containerizing areas.

                                        Page 6 of 10
     Conduct casual observations and corrections of visible emissions and releases of dust
      or debris on an ongoing daily basis, but conduct the specialized assessments and
      inspections as described in this Item at least 3 times each day.
    Method PD/Lead A4 of SSPC publication 95-06, Project Design, provides guidance on
      visible emissions assessments.
4. Reporting of Visible Emissions
    Report the results of the daily assessments in a log book or other report form.
    Document all cases where work has been halted due to unacceptable visible
      emissions or releases of material, the cleanup activities invoked, and the corrective
      action taken to avoid a reoccurrence. Provide the written report to the Department
      within 48 hours of the occurrence.

(c) High Volume Ambient Air Monitoring

1. Conduct high volume ambient air monitoring during paint removal and clean-up
   activities to confirm that emissions do not exceed the EPA National Primary and
   Secondary Ambient Air Quality Standards (NAAQS), or specific County or City regulations.
2. Comply with the acceptance criteria established in City or County regulations when
   applicable. Comply with the criteria established in 40 CFR 50 as summarized below if
   there are no local regulations governing high volume ambient air monitoring:
    TSP-Lead (Total Suspended Particulate-Lead) - Do not exceed 1.5 g/m3 averaged
        over a 90 day period. Place one (minimum) TSP-Lead Ambient Air Monitor(s) per site
        in the location acceptable to the Engineer. Conduct Ambient Air Monitoring for a
        period of one week prior to blasting, to two weeks after blasting start, as a minimum.
    PM-10 (Particulate Matter 10 Microns and Less in Aerodynamically Equivalent
        Diameter) - Do not exceed the equivalent of 150 g/m3 as a 24-hour average. Set up
        one per site, @ a minimum, unless otherwise directed by the Department. Place one
        (minimum) PM-10 Ambient Air Monitor(s) per site in the location acceptable to the
        Engineer. Conduct Ambient Air Monitoring for a period of one week prior to blasting,
        to two weeks after blasting start, as a minimum.
3. If the results are acceptable, at the direction of the Engineer, reduce monitoring to one
   (1) day per month, but resume if problems appear to be occurring as determined by
   visual assessments of the operations, or as otherwise directed by the Engineer. Change
   all monitor filters in the presence of the Inspector-In-Charge. Be responsible for damage
   or loss of monitors for the life of the contract.
4. If monitoring is conducted and the above criteria is violated, immediately stop work and
   make changes to the containment and/or work practices to achieve compliance. Note
   that exceedances may also result in City or County violations.

(d) Restrictions on Emissions to Ground (Soil), Water, and Sediment

1. Conduct all activities so that releases to the soil, water, sediment, or storm sewers do
   not occur.


                                        Page 7 of 10
2. If particulate or debris is released beyond the contained or protected areas, immediately
   shut down the emission-producing operations until the cause of the emissions is
   corrected.
3. Immediately clean up visible deposits of debris on the unprotected ground, on the soil,
   on or in the water or sediment, around storm sewers or drains, or in areas where rain
   water could carry the debris into storm sewers or drains. Take the appropriate
   corrective action to change work practices or to modify the containment to prevent
   emissions from occurring in the future.

(e) Final Cleaning/Clearance Evaluations

1. General
    Conduct an inspection of the project site and surrounding property and surfaces
      located within the likely dispersion zone of project dust and debris upon completion
      of project activities, and after all Contractor equipment and materials have been
