AIR EMISSIONS REGULATIONS:

Air Quality Status	Five areas are in nonattainment for both 8-hr ozone and PM-2.5; one area is in nonattainment for lead EPA's Nonattainment Areas
Major Source Threshold	PTE 250 tons(100 tons of listed sources) of any criteria pollutant in attainment areas. 100 tons of criteria pollutants in nonattainment areas.
Minor Source Permitting Exemption	See emission thresholds below
Minor Source Treatment	No limits (except for synthetic minor)
Emergency Generating Limits	PTE based on 500 hours of operation; emergency and standby generators that run less than 750 hours per year, 400 of which may be in the ozone season, are exempt from NOx emissions limits.

 

DE MINIMIS EXEMPTIONS

Sources that have a potential to emit less than the following are exempt from permitting:

• NOx, SO2 and VOC: 40 tons each
• PM-10: 15 tons
• CO: 100 tons and
• HAPs: 10 tons per year for individual HAPS and 25 tons for multiple HAPS.

State notification is recommended but no required for these sources; at a minimum sources should document emissions from such units in their internal files.

MINOR SOURCE PERMITTING

Sources in attainment areas with a potential to emit less than 250 tons per year of all criteria pollutants (this threshold is 100 tons in nonattainment areas) will be subject to an ambient air impact analysis. Controls may be required in order to meet National Ambient Air Quality Standards (NAAQS). Stack testing may be required to verify emission rates from a source to demonstrate compliance with any special conditions placed on the installation by the permit. Otherwise emission limits and control requirements are unlikely.

There is a 30-day public comment period and the entire permitting process takes about 90 days.

MAJOR NSR/PSD PERMITTING

If the unit is located in a nonattainment area then a potential to emit 100 tons of any criteria pollutant triggers NSR. A potential to emit 250 tons (100 tons of listed sources) per year of a criteria pollutant triggers PSD in attainment areas.

TREATMENT OF EMERGENCY ENGINES

Emergency units may be exempted from permitting if they agree to operate no more than 500 hours per year and if potential emissions at 500 hours are below de minimis levels. Emergency and standby engines that operate less than 750 hours per year, of which 400 may be in the ozone season, are exempt from NOx emissions limits.

SITING REQUIREMENTS FOR NON-UTILITY GENERATORS:

Onsite electrical generators can build facilities in Missouri without the approval of the Missouri Public Service Commission if they do so on their own property. However, if the infrastructure crosses the path of the Public Right of Way or if they wish to sell excess capacity to the grid, a certificate is needed from the PSC. The usual environmental permits are required from the Department of Natural Resources.

BUILDING, ZONING AND FIRE CODES:

Building Codes: Missouri does not have a statewide building code. Each county may voluntarily adopt any building code. [1] Counties must “adopt a current, calendar year 1999 or later edition, nationally recognized building code, as amended”. [2]

Energy Codes: There are no commercial energy codes in force. State-owned buildings must comply with ASHRAE 90.1-1989.

• State Energy Center

Fire Codes: Missouri does not have a statewide fire code. Each county may voluntarily adopt any fire code

• State Fire Marshal

Zoning: Zoning and planning happens at the local level. Check with each jurisdiction regarding their zoning codes.

A general overview of each state’s enacted codes can be found HERE.

The International Code Council Adoption page gives state-by-state adoption status of specific ICC codes, as well as information about code adoption by some municipal governments within that state.

Information about energy codes can be found at the DOE’s Building Codes for Energy Efficiency page or at the Building Codes Assistance Project.

INTERCONNECTION REQUIREMENTS:

In June 2007 Missouri enacted SB 54 requiring all utilities to offer interconnection to net-metered customer-generators using wind, photovoltaic, biomass, solar-thermal, hydroelectric, and fuel cells, up to 100 kW in capacity. The systems must be primarily intended to offset some of the customer’s own costs, and must be located on property owned by the customer.

EXIT FEES:

There are no statewide exit fee policies in place. However, no utilities charge exit fees.

UTILITY STANDBY RATES:

Missouri does not have a statewide policy on standby rates. Relevant provisions for Missouri utilities are summarized below.

Kansas City Power & Light Co - Schedule SGC: The standby rate is equal to the regular bill customer and demand charges (if customer was not generating on-site), plus real time pricing of standby power, plus reactive power charge, plus facilities & admin charges. Billing demand is based on maximum 15 minute demand with no ratchet. Rate information is available at: http://www.kcpl.com/about/ratesrules.html

Union Electric Co (Ameren) - Rider E: Standby and supplemental service is provided to customers who contract for a specific amount of standby demand with the utility. Actual energy usage is charged under the normal rate the site would be charged if they did not generate power. There are high demand charges compared to energy charges. Billing demand is based on maximum demand of the month or the contract demand. Rate information is available at: https://www2.ameren.com/business/Rates/ratesBundledElecFullSrvMO.aspx
