1.3.3.2 Containment

Prepare a Containment Plan for containing debris generated during paint removal operations selected by the Contractor. Identify in detail the containment system and the method of securing it in place that will be sufficiently robust to support the proposed means of paint removal as well as the procedures for removing debris. Contain debris generated during paint removal operations in accordance with the requirements of SSPC Guide 6 . Where required, verify the containment air pressure by instrument.

1.3.3.3 Visible Emissions Monitoring

Prepare a Visible Emissions Monitoring Plan including the provisions for halting work and correcting the containment in the event unacceptable emissions are observed. General statements must not be used; specific methods, procedures, and details are required. Measure the time of emissions in accordance with 40 CFR 60 , App A, Mtd 22. Monitor visible emissions for not less than 15 minutes of every hour. Calculate visible emissions for each hour by extrapolation. Visible emissions must not extend greater than 150 feet in any direction horizontal from the containment. Notify the foreman whenever visible emissions exceed 200 seconds in a 1 hour period. Whenever visible emissions exceed 300 seconds in a 2 hour period notify the foreman, shut down the job, and take corrective action. If the total observed visible emissions from the containment exceeds 5 percent of the work day, shut down the job and take corrective action to prevent such an occurrence. Document each time that the work is halted due to a violation of the visible emissions criteria.

Documentation must include the cause for shutdown and the corrective action taken to resolve the problem.

1.3.3.4 TSP Monitoring

Prepare a TSP Monitoring Plan for monitoring emissions of Total Suspended Particulates (TSP) in compliance with the requirements of EPA regulation

SECTION 09 97 02 Page 8

40 CFR 50.12 and this paragraph. The plan must include provisions for halting work and correcting the containment in the event unacceptable emissions occur. Position the air monitoring equipment in accordance with 40 CFR 58 , App E, Subpart (8). A minimum of two TSP monitors must be used at the project site. Perform monitoring 4 of the first 8 days and on a regular basis thereafter for a sum total of 25 percent of the time surface preparation and debris cleanup are performed. If air quality regulatory limits are not met, require air monitoring to be repeated immediately after corrective actions have been taken. Also conduct preproject TSP monitoring. Conduct the preproject TSP monitoring a minimum of 2 weeks prior to the beginning of the project and continue the monitoring for a minimum of 3 days to establish background levels.
