Level 1 Emissions are defined as random visible emissions of a cumulative duration of no more than 1 percent of the workday or approximately 5 minutes in an 8 -hour day. Level 1 is required for all structures. The contractor’s QC person or Competent Person 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, routinely observe the work area. Immediately report unacceptable emissions to QC or supervisory personnel, to the Competent Person in the case of toxic metals projects, and to the engineer. When unacceptable emissions are detected, locate and immediately correct the source of the emissions. Retain the records on site and make them available to the engineer.

Start monitoring no earlier than 1/2-hour before blast cleaning starts and run for the entire duration of the cleaning activity or 7 -hours whichever is greater.
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, repeat monitoring for 2 consecutive days every mont h thereafter during the work shift while blast cleaning or other dust producing operations are underway. STEEL SIGN STRUCTURES SECTION 617 299 ii. When the results of the original 10 -days of monitoring or the periodic monthly tests are unacceptable, continue full time monitoring. Monthly monitoring may be initiated or resumed only when approved, and only after the results of the testing indicates that the containment is controlling emi ssions. iii. Resume full time monitoring when unacceptable visible emissions or residues are observed on the ground or water.

Prevent paint chips from falling onto the ground. ii. When pressure washing all other systems (systems other than inorganic zinc, inorganic zinc/vinyl, or systems that contain toxic metals), collect all dislodged paint chips, but the water need not be captured. When working over ground, chips may be coll ected from the ground in lieu of utilizing containment screens, provided all chips are collected before the end of the shift.

Dispose of collected paint chips and debris per the applicable regulations. iii. For roadway joints and other small areas approved by the engineer, High Efficiency Particulate Air (HEPA) filter vacuum shrouded power tools may be used in lieu of containment in areas of paint containing toxic or nontoxic metals. Vacuum -shrouded powe r tools may eliminate the need for containment if it can be demonstrated that all paint chips and debris are sufficiently collected by the vacuum.
