1.9 PROJECT/SITE CONDITIONS

A. Climate:

No paint shall be applied when the air or surface temperature, as measured in the shade, is below that which is recommended by the manufacturer. Paint shall not be applied to wet or damp surfaces, and shall not be applied in rain, snow, fog, mist, or when the surface temperature will be less than 5 F above the dew point. No paint shall be applied when it is expected that the surface temperature will drop below the manufacturer's recommendation within 2 - 4 hours after the application of the paint. Dew or moisture condensation should be anticipated, and if such conditions are prevalent, painting shall be delayed until it is certain that the surfaces are dry. In addition, the days painting shall be completed well in advance of the probable time of day when moisture condensation will occur in order to permit the film the required drying time as specified by the manufacturer prior to the formation of moisture.

B. Ventilation:

Provide ventilation during coating curing stage in confined or enclosed areas in accordance with AWWA D102-06, Section A.7.5. Forced air ventilation shall be maintained for a minimum of four (4) days following interior coating application to assist in curing process.

C. Dust and Contaminants:

Schedule coating work to avoid excessive dust and airborne contaminants. Protect work areas from excessive dust and airborne contaminants during coating application and curing.

A. Containment:

During surface preparation, airborne particulates and debris from the removal of coatings should be effectively contained to prevent contamination of surrounding air, soil and/or water. Minimizing or eliminating the airborne particulate by containing and collecting debris generated should reduce these environmental hazards. The control of these airborne particulates should comply with SSPC Guide 6 Guide for Containing Debris Generated During Paint Removal Operations as well as all local, state and federal regulations.

B. Disposal:

Due to the date of the original installation of this tank (2001) and the nature of all subsequent coatings applied, it can be safely assumed that all existing interior and exterior coatings on this tank are lead-free, therefore normal blasting and disposal procedures can be used. If the contractor has any concerns regarding hazardous existing materials , it shall be brought to the attention of the CO and EPM immediately for further discussion and planning.
