Current through Register Vol. 50, No. 9, September 20, 2024
A. Applicability
1. This regulatory permit authorizes the
flaring of gaseous materials other than natural gas (e.g., propane, ethylene,
propylene, ammonia) resulting from metering, purging, and maintenance
operations, subject to the requirements established herein, upon notification
that the department has determined the application (i.e., notification form)
submitted in accordance with Subsection G of this Section to be complete. The
material to be flared may be supplemented with natural gas.
2. The material to be flared must have a
higher heating value greater than or equal to 300 Btu per standard cubic
foot.
B. The flare must
be capable of accommodating the maximum amount of material to be combusted at
any point during the flaring event.
C. Opacity
1. Smoke. The emission of smoke shall be
controlled so that the shade or appearance of the emission is not darker than
20 percent average opacity, except that the emissions may have an average
opacity in excess of 20 percent for not more than one 6-minute period in any 60
consecutive minutes.
2. Particulate
Matter. The emission of particulate matter shall be controlled so that the
shade or appearance of the emission is not denser than 20 percent average
opacity, except that the emissions may have an average opacity in excess of 20
percent for not more than one 6-minute period in any 60 consecutive
minutes.
3. Emissions of smoke or
suspended particulate matter that pass onto or across a public road and create
a traffic hazard by impairment of visibility, as defined in LAC 33:III.111, or
intensify an existing traffic hazard condition are prohibited.
4. The owner or operator of the flare shall
conduct a 6-minute opacity reading in accordance with method 9 of 40 CFR 60,
Appendix A, upon request of the department. Results shall be kept on-site and
available for inspection by the Office of Environmental Compliance.
D. The authorization for the
flaring event associated with the specific metering, purging, or maintenance
operation addressed by the application submitted in accordance with Subsection
G of this Section shall remain effective for 60 days following the date on
which the department determines that the application is complete.
E. Flaring events with a duration of more
than 10 calendar days shall not be authorized by this regulatory permit and
must be approved separately by the department.
F. When an ozone action day has been declared
by the department, flaring of ethylene or propylene shall be restricted to
between the hours of 4 p.m. and 10 a.m.
G. Notification Requirements
1. The following information shall be
submitted to the Office of Environmental Services using the appropriate form
provided by the department:
a. name of the
owner or operator;
b. material to
be flared;
c. estimated volume of
the material to be flared;
d.
reason for the flaring event;
e.
physical location;
f. date(s) and
expected duration of the flaring event; and
g. estimated emissions of criteria pollutants
and toxic air pollutants (TAPs) associated with the flaring event. TAPs are
listed in LAC 33:III.5112, Tables 51.1 and 51.3.
2. A copy of the notification required by
Paragraph G.1 of this Section shall be submitted to the appropriate DEQ
regional office.
3. A separate
notification shall be submitted for each flaring event.
H. Monitoring, Recordkeeping, and Reporting
1. The volume of material combusted during
the flaring event shall be monitored using a flow meter. Alternatively, the
volume may be determined using engineering calculations.
2. The following information shall be
recorded and submitted to the Office of Environmental Services no later than 30
calendar days after completion of the flaring event:
a. date(s) and duration of the flaring
event;
b. actual volume of material
flared including calculations if the volume was not monitored using a flow
meter; and
c. actual criteria
pollutant and TAP emissions associated with the flaring event.
I. In accordance with
LAC 33:III.223, Table 1, the fee for this regulatory permit shall be $500.
There shall be no annual maintenance fee associated with this regulatory
permit.
