Question 1 Estimate the areas and thicknesses of the major protective coating systems inside containment, including aluminum and zine base paints, epoxy paints, acrylic lacquer, etc.
Response
82,000 square feet; 3.0 - 6.3 mils dry film thickness (DFT).
Question 2 Indicate whether these coating systems and their methods of application were qualified according to the recommendations of Regulatory Guide 1.54.
Response
The Haddam Neck P' sat was constructed prior to the issuance of Regulatory Guide 1.54.
As such, the coatings and their application are not qualified to the guide.
