MISSISSIPPI
DE MINIMIS EXEMPTIONS:
Sources that have a potential to emit less than 10 tons per year of each criteria pollutant, 1 ton per year
of an individual hazardous pollutant and 2.5 tons per year of any combination of hazardous pollutants are exempt
from permitting. These sources are not required to notify the state.
MINOR SOURCE PERMITTING:
Sources with a potential to emit greater than the exempted sizes above must obtain a minor source permit. The
state does not require modeling, but does enforce a 40% opacity limit and a 4.8 lb/MMBtu SO2 limit. A PM limit
will be based on the unit's size in BTUs, but the PM limit is rarely an issue for applicants. No other controls
are likely.
There is a 30-day public comment period for sources with a potential to emit greater than 100 tons per year
of a criteria pollutant. The entire permitting process takes 30 days if there is not a comment period, but up to
120 with a comment period.
MAJOR NSR/PSD PERMITTING:
A potential to emit 250 tons per year of a criteria pollutant triggers PSD.
TREATMENT OF EMERGENCY ENGINES:
Emergency engines can have their potential to emit based on 500 hours per year if they agree to operate only
for blackouts and maintenance. Based on this potential to emit calculation the unit may qualify for the de minimus
exemption above. Otherwise the source is permitted normally.
All electric power-generating facilities are required to acquire a Facility Certificate from the Mississippi
Public Service Commission. In order to obtain this Certificate, the petitioner must establish that the
proposed facility fills some demand for public convenience and necessity. However, the PSC will exempt on-site
power producers from these requirements. Before the Certificate is granted the applicant must provide proof
that the proposed facility is in compliance with all relevant state environmental regulations. The Mississippi
Public Service Commission also conducts public hearings on the issue.
§ 77-3-14. Certificate of public convenience and necessity required for construction of electrical generating
and transmitting facilities
(1) Notwithstanding the provisions of Section 77-3-11, Mississippi Code of 1972, and Section 77-3-13, Mississippi
Code of 1972, no public utility or other person shall begin the construction of any facility for the generation
and transmission of electricity to be directly or indirectly used for the furnishing of public utility service
in this state, even though the facility be for furnishing the service already being rendered, without first
obtaining from the commission a certificate that the public convenience and necessity requires, or will require,
such construction.
(6) The certification requirements of this section shall not apply to persons who construct an electric generating
facility primarily for that person's own use and not for the primary purpose of producing electricity, heat or
steam for sale to or for the public for compensation; and the commission may provide for exemption from
certification requirements for cogeneration facilities and small standby facilities; provided, however, that
such persons shall, nevertheless, be required to report to the commission the proposed construction of such a
facility before beginning construction thereof.

is up to local jurisdictions to adopt and enforce building codes.

The
Energy Investment Loan Program provides financial assistance in the form of a loan to individuals,
partnerships, or corporations, for either capital improvements, or in the design and development of
innovative energy conservation processes. The principal purpose of the improvement should be the
development and demonstration of efficient, environmentally acceptable and commercially feasible
technologies, techniques or processes while effectively utilizing existing alternative and conventional
energy resources.
The Energy Investment Program offers loans at a rate of 3% below the Prime Interest rate prevailing at the
time of closing, in amounts up to $300,000, which can be amortized over a period of time not to exceed 7
years. Loans are secured by a lien or liens on either the measures installed and/or other unencumbered
business assets, personal guarantees by the firm's or organization's owner or officers, surety bonds, or a
combination of these.
