Headline: Univers Condensed Current Emissions Technologies Bold 40 pt Headline: Univers Condensed Bold: 24 pt Nick Detor MIRATECH Corporation EGSA Spring Convention 2008 Introduction/Agenda Overview of Federal and Selected Local
Overview of Federal and Selected Local Regulations Catalyst Technologies
– Decision Tree – How to choose – SCR (Selective Catalytic Reduction) – NSCR (Non- Selective Catalytic Reduction, e.g. 3-Way Catalyst) DIY Emission Retrofits
Federal Regulations
– Diesel Tier levels (1, 2, 3, 4) – New Source Performance Standards for gas/NG/LPG
State/Local Regulations
– California Dist. Gen. standards – New DG regulations in northeast, TX, etc.
Customer Drivers
– Peak Shaving/Demand Response – Emission Offset Creation – LEED Certification – Title V Netting (Synthetic Minor) – Issues with HVAC intakes – Good Neighbor
The Clean Air Act of 1990 turned over the rule making and enforcement of emission regulation to the states. Rules are still based on the National Ambient Air Quality Standards, and the federal government retains the right to step in if states are not meeting their air quality goals. States can also choose to enact regulations more stringent than the federal Tier standards above.
