Section 096-124-3 - Standards
A. Unless otherwise specified in this rule, no owner or operator subject to this Chapter shall discharge into the atmosphere any gases which contain TRS in excess of 0.75 pounds per hour or five (5) parts per million (ppm) by volume dry basis on a twelve (12)-hour block average basis, and which are from a LVHC system, or after the dates in Section 3(D), 3(E), and 3(L), from HVLC systems, steam stripper collection systems or alternative TRS control systems unless at least one of the following conditions is met:
(1) The gases are combusted in a lime kiln subject to the provisions of Section 3(K) and Section 4(A) of this Chapter, and the requirements of 40 CFR Section 60.283(a)(5), as applicable; or
(2) The gases are combusted in a recovery furnace subject to the provisions of Section 3(H), 3(I), and Section 4(A) of this Chapter, and the requirements of 40 CFR Sections 60.283(a)(2) or (a)(3), as applicable; or
(3) The gases are combusted in an incinerator, boiler, or other device subject to the provisions of Section 4(B), and are subjected to a minimum temperature of 1200oF for at least 0.5 seconds.
B. The LVHC collection system shall have a primary control strategy and a backup control strategy. Both strategies shall meet the requirements of this Chapter.
C. No owner or operator subject to this Chapter shall allow venting of TRS from the LVHC or associated equipment that is required to be controlled which:
(1) exceeds 40 minutes in duration; or
(2) contributes to an aggregate TRS venting of more than 1.0% of quarterly operating time.
D. Owners and operators subject to this Chapter shall collect and control TRS emissions greater than 0.75 pounds per hour from the brownstock washer system as to meet the conditions of Section 3(A) by April 17, 2007. Sources which propose replacing a brownstock washer line with a new system will have until the MACT standard compliance date to meet the conditions in Section 3(A) of this Chapter.
E. By April 17, 2007, each HVLC collection system subject to this Chapter shall maintain a 96% collection and control uptime based on quarterly brownstock washer system operating time on a total mass weighted basis.
F. Each steam stripper collection system or alternative TRS control system, that is not part of an HVLC system, subject to this Chapter shall maintain a 99% collection and control of TRS gases when operating based on quarterly system operating time.
G. By April 15, 2001, each Kraft pulp mill subject to this Chapter shall maintain a written preventative maintenance program for their respective TRS gas collection systems.
H. No owner or operator subject to this Chapter shall discharge into the atmosphere, any gases which contain TRS in excess of five (5) ppm by volume dry basis, corrected to eight (8)% oxygen on a twelve (12)-hour block average basis, and which are from a Kraft recovery furnace, unless equipped with a wet bottom ESP using black liquor.
I.No owner or operator subject to this Chapter shall discharge into the atmosphere any gases which contain TRS in excess of fifteen (15) ppm by volume dry basis, corrected to eight (8)% oxygen on a twelve (12)-hour block average basis, and which are from any Kraft recovery furnace with a wet-bottom ESP employing black liquor.
J. No owner or operator subject to this Chapter shall discharge into the atmosphere from any smelt dissolving tank, any gases which contain TRS in excess of 0.033 lb./ton black liquor solids as H2S.
K. No owner or operator subject to this Chapter shall discharge into the atmosphere, any gases which contain TRS in excess of twenty (20) ppm by volume dry basis, corrected to ten (10)% oxygen on a twelve (12)-hour block average basis, and which are from any lime kiln.
L.By January 1, 2004 each Kraft pulp mill facility shall submit for approval by the Department a Best Practical Treatment (as defined in 38 M.R.S.A. §§582(5-A) and 590(3)) analysis for control of TRS from miscellaneous sources and for the facility's waste water treatment system. Implementation of this Best Practical Treatment shall occur no later than July 1, 2007.
M. By January 1, 2002, each Kraft pulp mill facility shall submit to the Department an inventory of TRS sources with emission levels greater than 0.5 lbs/hr.
