Chapter 3745-73 Total Reduced Sulfur

3745-73-01 Definitions and reference to materials.

The definitions in this rule shall apply to this chapter.

(A) "Black liquor" means the spent cooking liquor, composed of a mixture of dissolved lignins and inorganic compounds, which remains after the digestion of wood chips in the Kraft pulping process.

(B) "Black liquor solids" means the dry solids which enter the recovery furnace in the black liquor.

(C) "Condensate stripper system" means a system in which total reduced sulfur gasses, partially dissolved in the digester and multiple effect evaporator off-gas condensate, are stripped by means of a countercurrent flow of air or steam in multi-stage columns.

(D) "Digester system" means any continuous or batch process in which white liquor is used to cook the wood pulp, and includes any associated flash tanks, blow tanks, chip steamers and condensors.

(E) "Kraft pulp mill" means a wood pulping mill which uses an alkaline sulfide solution containing sodium hydroxide and sodium sulfide (white liquor) in the wood digesting process.

(F) "Lime kiln" means a unit used to calcine calcium carbonate, commonly known as "lime mud," into calcium oxide, commonly known as "quicklime."

(G) "Multiple-effect evaporator system" means the multiple-effect evaporator including any associated condensors and hotwells used to concentrate the black liquor.

(H) "Recovery furnace" means a straight Kraft recovery furnace including any direct contact evaporators, designed to recover chemicals necessary for the pulp cooking process through the combustion of black liquor containing less than seven per cent liquor such as neutral sulfite semichemical from a soda-based semichemical pulping process on a quarterly basis.

(I) "Smelt dissolving tank" means a vessel used for dissolving smelt from a recovery furnace.

(J) "Soda-based semichemical pulping operation" means any operation in which pulp is produced from wood by cooking or digesting wood chips in a soda-based semichemical such as neutral sulfite semichemical.

(K) "Total reduced sulfur" means the sum of the sulfur compounds hydrogen sulfide, methyl mercaptan, dimethyl sulfide and dimethyl disulfide, that are released during the Kraft pulping operation and measured by methods specified in rule 3745-73-04 of the Administrative Code.

3745-73-02 Certification and compliance time schedules.

(A) All compliance times and other deadlines set forth in paragraph (C) of this rule shall be measured from November 1, 1984.

(B) No later than February 1, 1985, any owner or operator of any air contaminant source subject to rule 3745-73-03 of the Administrative Code shall either:

(1) Certify in writing to the director that the source is in compliance with all requirements of rule 3745-73-03 of the Administrative Code. The certification shall include: description of the equipment, the Ohio environmental protection agency permit application number(if assigned), all necessary data and calculations necessary to confirm the compliance status, and an application for a permit to operate the source in accordance with rule 3745-35-02 of the Administrative Code if the sources does not possess an effective permit; or

(2) Submit an application for a permit-to-operate or an application for modification of a permit-to-operate in accordance with rule 3745-35-02 of the Administrative Code. The application shall include a compliance program and time schedule which will bring the source into compliance with all the requirements of this rule and rule 3745-73-03 of the Administrative Code as expeditiously as practicable but in no event later than the dates specified in paragraph (C) of this rule, and shall identify all reasonable interim control measures.

(C) Any owner or operator of an air contaminant source in violation of the limitations specified in rule 3745-73-03 of the Administrative Code shall comply with the requirements as expeditiously as practicable, but in no event later than the dates specified in this paragraph:

(1) Owners or operators of any recovery furnace in violation of paragraph (A)(1) of the rule 3745-73-03 of the Administrative Code shall achieve final compliance by March 1, 1988.

(2) Owners or operators of any digester system in violation of paragraph (A)(2) of rule 3745-73-03 of the Administrative Code shall achieve final compliance by July 1, 1986.

(3) Owners or operators of any multiple-effect evaporator system in violation of paragraph (A)(3) of rule 3745-73-03 of the Administrative Code shall achieve final compliance by July 1, 1986.

(4) Owners or operators of any lime kiln in violation of paragraph (A)(4) of rule 3745-73-03 of the Administrative Code shall achieve final compliance by November 1, 1986.

(5) Owners or operators of any condensate stripper system in violation of paragraph (A)(5) of rule 3745-73-03 of the Administrative Code shall achieve final compliance by July 1, 1986.

(6) Owners or operators of any smelt dissolving tank in violation of paragraph (A)(6) of rule 3745-73-03 of the Administrative Code shall achieve final compliance by July 1, 1986.

(7) The director may extend the final compliance obligation for any facilities within an existing Kraft pulp mill, for a period not to exceed four years after the effective date of the "Ohio State Implementation Plan" for the control of total reduced sulfur emissions, upon a showing that because of the limited remaining useful life of such facilities, they will be replaced or modified in a manner which makes them subject to federal new source performance standards.

(8) The director may modify the requirements of rule 3745-73-03 of the Administrative Code as those requirements apply to a facility, upon a showing that compliance with a requirement within the prescribed time is technically infeasible, economically unreasonable, or impossible because of conditions beyond the control of the applicant. Any such determination by the director shall be based upon consideration of the remaining useful life of the facility and such other factors as the director deems appropriate.

(B) No owner or operator of any Kraft pulp mill shall cause or permit the emission of total reduced sulfur from any source not regulated by paragraph (A) of this rule, but which is used as a point of incineration of reduced sulfur emissions from a source regulated by paragraph (A) of this rule, to exceed a maximum of five parts per million on a dry basis and as a twelve-hour average, corrected to eight per cent oxygen.

(C) Emissions from recovery furnaces which exceed the emission limits contained in this rule, from sources on which construction or modification commenced on or before September 24, 1976, shall not be considered excess emissions if: (1) not more than one per cent of all twelve-hour averages of total reduced sulfur per quarter exceed the standard specified in paragraph (A)(1) of this rule; (2) proper operation and maintenance have been performed; and (3) there have been no start-ups, shutdowns, or malfunctions.

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see paragraph (L) of rule 3745-73-01 of the Administrative Code titled" Reference to materials."]

(A) Compliance with any applicable emission limit for total reduced sulfur as specified in rule 3745-73-03 of the Administrative Code shall be determined according to either:

(1) One of the reference methods described in 40 CFR Part 60, Appendix A; or
