Current through September 24, 2024
A.
Smoke.
(1) No person shall cause, permit, or
allow the emission of smoke from a point source into the open air from any
manufacturing, industrial, commercial or waste disposal process which exceeds
forty (40) percent opacity subject to the exceptions provided in Rule 1.3.A(2)
& (3).
(2) Startup operations
may produce emissions which exceed 40% opacity for up to fifteen (15) minutes
per startup in any one hour and not to exceed three (3) startups per stack in
any twenty-four (24) hour period.
(3) Emissions resulting from soot blowing
operations shall be permitted provided such emissions do not exceed 60 percent
opacity, and provided further that the aggregate duration of such emissions
during any twenty-four (24) hour period does not exceed ten (10) minutes per
billion BTU gross heating value of fuel in any one hour.
B. Equivalent Opacity. No person shall cause,
allow, or permit the discharge into the ambient air from any point source or
emissions, any air contaminant of such opacity as to obscure an observer's view
to a degree in excess of 40% opacity, equivalent to that provided in Rule
1.3.A.(1) This shall not apply to vision obscuration caused by uncombined water
droplets.
C. General Nuisances. No
person shall cause, permit, or allow the emission of particles or any
contaminants in sufficient amounts or of such duration from any process as to
be injurious to humans, animals, plants, or property, or to be a public
nuisance, or create a condition of air pollution.
(1) No person shall cause or permit the
handling or transporting or storage of any material in a manner which allows or
may allow unnecessary amounts of particulate matter to become airborne.
(2) When dust, fumes, gases, mist,
odorous matter, vapors, or any combination thereof escape from a building or
equipment in such a manner and amount as to cause a nuisance to property other
than that from which it originated or to violate any other provision of this
regulation, the Commission may order such corrected in a way that all air and
gases or air and gasborne material leaving the building or equipment are
controlled or removed prior to discharge to the open air
D. Fuel Burning
(1) Fossil Fuel Burning. The maximum
permissible emission of ash and/or particulate matter from fossil fuel burning
installations shall be limited as follows:
(a) Emissions from installations of less than
10 million BTU per hour heat input shall not exceed 0.6 pounds per million BTU
per hour heat input.
(b) Emissions
from installations equal to or greater than 10 million BTU per hour heat input
but less than 10,000 million BTU per hour heat input shall not exceed an
emission rate as determined by the relationship
E = 0.8808 * I
-0.1667
where E is the emission rate in pounds per million BTU per
hour heat input and I is the heat input in millions of BTU per hour.
(c) Emissions from installations
equal to or greater than 10,000 million BTU per hour heat input shall not
exceed 0.19 pounds per million BTU per hour heat input.
(2) Combination Boilers. Fuel burning
operations utilizing a mixture of combustibles such as, but not limited to,
fossil fuels plus bark, oil plus bark, or spent wood, or water treatment
by-products sludge, to produce steam or heat water or any other heat transfer
medium through indirect means may be allowed emission rates up to 0.30 grains
per standard dry cubic foot.
E. Kraft Process Recovery Boilers. The
emissions of particulate matter from a recovery furnace stack shall not exceed
four (4) pounds per ton of equivalent air-dried Kraft pulp produced at any
given time.
F. Manufacturing
Processes.
(1) General. Except as otherwise
specified, no person shall cause, permit, or allow the emission of particulate
matter in total quantities in any one hour from any manufacturing process,
which includes any associated stacks, vents, outlets, or combination thereof,
to exceed the amount determined by the relationship
E = 4.1 p
0.67
where E is the emission rate in pounds per hour and p is the
process weight input rate in tons per hour.
Conveyor discharge of coarse solid matter may be allowed if
no nuisance is created beyond the property boundary where the discharge
occurs.

per ton of equivalent air-dried Kraft pulp.
(b) Lime Kilns. The emission of particulate
matter from lime kilns shall not exceed one pound per ton of equivalent
air-dried Kraft pulp.
(c) Smelt
Tanks. The emission of particulate matter from smelt tanks shall not exceed
one-half pound per ton of equivalent air-dried Kraft pulp.
G. Open Burning. The
open burning of residential, commercial, institutional, or industrial solid
waste, is prohibited, except as specified herein. This prohibition does not
apply to infrequent burning of agricultural wastes in the field, silvicultural
wastes for forest management purposes, land-clearing debris, debris from
emergency clean-up operations, and ordnance; and permitted open burning at
hazardous waste disposal facilities subject to regulation under Subtitle C of
the Federal Resource Conservation and Recovery Act (RCRA).
(1) Fires set for the burning of agricultural
wastes in the field and/or silvicultural wastes for forest management purposes
must meet the following conditions.
(a) A
Permit must be obtained from the Mississippi Forestry Commission.
(b) The open burning must occur within a time
period allowing adequate diffusion of air pollutants as defined by the permit
and the daily weather guides issued by the National Weather Forecast
Office.
(c) Starter or auxiliary
fuels may consist of dried vegetation, petroleum derived fuels of the gasoline,
kerosene, or light fuel oil types (diesel), or a combination thereof. Use of or
burning of other combustible material that causes excessive visible emission
(e.g., rubber tires, plastic materials, etc.) is
prohibited.
(2) Open
burning of land-clearing debris must not use starter or auxiliary fuels which
cause excessive smoke (rubber tires, plastics, etc.); must not be performed if
prohibited by local ordinances; must not cause a traffic hazard; must not take
place where there is a High Fire Danger Alert declared by the Mississippi
Forestry Commission or Emergency Air Pollution Episode Alert imposed by the
Executive Director and must meet the following buffer zones.
(a) Open burning without a forced-draft air
system must not occur within 500 yards of an occupied dwelling.
(b) Open burning utilizing a forced-draft air
system on all fires to improve the combustion rate and reduce smoke may be done
within 500 yards of but not within 50 yards of an occupied dwelling.
(c) Burning must not occur within 500 yards
of commercial airport property, private air fields, or marked off-runway
aircraft approach corridors unless written approval to conduct burning is
secured from the proper airport authority, owner or operator.
(3) Permitted open burning at a
hazardous waste disposal facility subject to regulation under Subtitle C of
RCRA is considered a stationary source of air pollution subject to Mississippi
air emission permitting regulations.
(4) The prohibition of open burning of
residential solid waste applies to open burning of leaves and other yard waste
by residential property owners, except when the Department has deferred the
regulation of the burning of leaves and other yard wastes to a county board of
supervisors and/or municipal governing body, and that county or municipal
governing body has in effect a local ordinance that regulates such open burning
and has been approved by the Department. Local ordinances approved by the
Department must provide that the leaves or other yard waste is burned on the
residential property where it originated. Approved local ordinances must also
be deemed protective of air quality and public welfare by the Department and
must provide for appropriate burning prohibitions and restrictions during Air
Quality Action Days. Additionally, approved local ordinances must include fire
safety provisions including prohibitions and restrictions on open burning
coordinated through the State Forestry Commission during dry weather
conditions.
(5) Air Quality Action
Days. Open burning of agricultural wastes and silvicultural wastes described in
G(1) above, open burning of land-clearing debris described in G(2) above,
permitted open burning at a hazardous waste disposal facility described in G(3)
above, and open burning of residential leaves and other yard wastes described
in G(4) above are prohibited in the specified county(ies) when an Air Quality
Action Day is declared by the Executive Director. Certain Air Quality Action
Days declared by the Executive Director may be designated as Ozone Action Days
in DeSoto County, Hancock County, Harrison County and Jackson County. Ozone
Action Days shall be noticed the evening before on the MDEQ website and/or with
local news media. The Mississippi Department of Transportation, Mississippi
State Forestry Commission, local fire officials, and County Emergency
Management Agencies (EMA) shall also be notified the evening before an Ozone
Action Day.
H.
Incineration.
(1) The maximum discharge of
particulate matter from any incinerator, except those specified in paragraph
(2) or (3) of this rule, or those specified in Rule
1.6 and
1.12 shall not exceed 0.2 grains per
standard dry cubic foot of flue gas calculated to twelve percent (12%) carbon
dioxide by volume for products of combustion. This limitation shall apply when
the incinerator is operating at design capacity.
The carbon dioxide produced by combustion of any auxiliary
fuels shall be excluded from the calculation to twelve percent (12%) carbon
dioxide. After May 8, 1970, any new equipment shall be of the multiple chamber
type or its equivalent for emission control. In critical areas where an
installation is in close proximity to a residential area, an incinerator,
except those specified in paragraph (2) of this rule, or those specified in
Rule
1.6 and
1.12, shall be limited to emissions of
0.1 grains per standard dry cubic foot of flue gases calculated to twelve
percent (12%) carbon dioxide by volume for products of
combustion.
(2) The maximum
discharge of smoke from the incineration of waste material resulting totally
from the ginning of cotton shall not obscure an observer's view to a degree in
excess of 40% opacity.
Start-up operations may produce emissions which exceed 40%
opacity for up to fifteen minutes per start-up in any one hour not to exceed
three (3) start-ups in any twenty-four (24) hour period.
After July 1, 1994, the emission limitation specified in
paragraph (1) of this rule shall also be applicable to cotton gin waste
incinerators.
(3) The
emission limitation in paragraph (1) above does not apply to afterburners,
flares, thermal oxidizers, and other similar devices used to reduce the
emissions of air pollutants from processes.
I. Sampling Ports.
(1) New Equipment: The owner or operator of
any new air pollution control equipment, obtained after May 8, 1970, and vented
to the atmosphere, shall have necessary sampling ports and ease of
accessibility.
(2) Existing
Equipment: The owner or operator of air pollution control equipment that is in
existence prior to May 8, 1970, shall provide the necessary sampling ports and
ease of accessibility when deemed necessary by the Permit Board.
J. More Restrictive Emission
Limits. The Commission reserves the right to prescribe more stringent emission
limits as it deems necessary in problem areas. The expansion, alteration, or
establishment of a new industry may also result in the prescription of more
stringent emission limits.
