What Is the MACT Model Point Value and How Is it Used in the Final Boat NESHAP?
The MACT model point value is a number calculated for each open molding operation and is a substitute for emissions levels. The MACT model point value is a way to rank the relative performance of different resin and gel coat emissions reduction techniques. This approach allows the creation of control strategies using different resin and gel coat emissions reduction techniques. The final NESHAP provides equations to calculate MACT model point values based on HAP content and application method for each material used. These MACT model point values are then averaged and compared to limits in the final NESHAP to determine if the molding operations are in compliance. The MACT model point values have units of kg of HAP per megagram of resin or gel coat applied. It is important to note that the MACT model point values are surrogates for emissions, and the MACT model point value equations are used only for determining compliance with the emission limits for open molding operations.
