Authority: IC 13-14-8; IC 13-17-3-4; IC 13-17-3-11
Affected: IC 13-15; IC 13-17
Sec. 7.
(a) In
addition to the requirements in section 1(d) of this rule, and the requirements
in section 6 of this rule, the owner or operator of a secondary lead smelter
using a total enclosure shall do the following:
(1) Submit a monitoring system plan
describing the installation and operation of a continuous monitoring system
that meets the requirements of subdivisions (2) and (3). The plan shall be
postmarked or hand delivered to the department one hundred twenty (120) days
prior to installation of the continuous monitoring system.
(2) The owner or operator of a secondary lead
smelter shall install, operate, and maintain a minimum of one (1) building
digital differential pressure monitoring system to continuously monitor each
total enclosure at each of the following three (3) walls in each total
enclosure that has a total ground surface area of ten thousand (10,000) square
feet or more:
(A) The leeward wall.
(B) The windward wall.
(C) An exterior wall that connects the
leeward and windward wall at a location defined by the intersection of a
perpendicular line between a point on the connecting wall and a point on its
furthest opposite exterior wall, and intersecting within plus or minus ten (10)
meters of the midpoint of a straight line between the two (2) other monitors
specified. The midpoint monitor must not be located on the same wall as either
of the other two (2) monitors.
(3) The owner or operator of a secondary lead
smelter shall install and maintain a minimum of one (1) building digital
differential pressure monitoring system at the leeward wall of each total
enclosure that has a total ground surface area of less than ten thousand
(10,000) square feet.
(b) Within one hundred eighty (180) days
after written approval of the continuous monitoring system plan by the
department, the owner or operator of a secondary lead smelter shall install and
operate a continuous monitoring system that consists of the following:
(1) A digital differential pressure sensor
capable of measuring pressure within a range of one-hundredth (0.01) to
two-tenths (0.2) millimeters mercury (five-thousandths (0.005) to
eleven-hundredths (0.11) inches of water) with a minimum accuracy of plus or
minus one-thousandth (0.001) millimeters of mercury (five ten-thousandths
(0.0005) inches of water).
(2) A
processor.
(3) An alarm.
(4) A continuous recording device.
(c) The owner or
operator of a secondary lead smelter shall calibrate each digital differential
pressure monitoring system in accordance with the manufacturer's specifications
at least once every twelve (12) calendar months or more frequently if
recommended by the manufacturer.
(d) The owner or operator of a secondary lead
smelter shall obtain prior written approval from the department for any changes
to the location or operation of the continuous monitoring system.
(e) The owner or operator of a secondary lead
smelter shall initiate corrective actions within thirty (30) minutes of a
monitoring system alarm.
(f) The
owner or operator of a secondary lead smelter shall notify the department
within seven (7) days of any physical changes to the total enclosure including,
but not limited to, ventilation capacity and building size.
(g) The owner or operator of a secondary lead
smelter shall maintain the following on site for a period of three (3) years
and have available the following records for an additional two (2) years:
(1) Records of the pressure differential.
(2) Logs of monitoring system
alarms, including date and time.
(3) Logs of corrective actions, including
date and time.
