[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 (AA) of this rule entitled "Referenced materials."]

Terms defined in sections 313(b)(1)(C) and 329 of Title III, Emergency Planning and Community Right-to-Know Act, of the Superfund Amendments and Reauthorization Act of 1986, and not explicitly defined herein are used within the meaning given in Title III. For the purpose of this chapter:

(A)

(1) "Act" means Title III, Emergency Planning and Community Right-to-Know Act, of the Superfund Amendments and Reauthorization Act of 1986, contained in 42 USC sections 11001 to 11050.

(2) "Article" means a manufactured item which conforms to the following:

(a) Is formed to a specific shape or design during manufacture.

(b) Has end-use functions dependent in whole or part upon its shape or design during end use.

(c) Does not release a toxic chemical under normal conditions of processing or use of that item at the facility or establishment.

(B)

(1) "Benificiation" means the preparation of ores to regulate the size (including crushing and grinding) of the product, to remove unwanted constituents, or to improve the quality, purity, or grade of a desired product.

(2) "Boiler" means an enclosed device using controlled flame combustion and having either of the following characteristics:

(a) The unit conforms to the following:

(i) Has physical provisions for recovering and exporting thermal energy in the form of steam, heated fluids, or heated gases.

(ii) The unit's combustion chamber and primary energy recovery section is of integral design meaning that the combustion chamber and the primary energy recovery section (such as waterwalls and superheaters) are physically formed into one manufactured or assembled unit. A unit in which the combustion chamber and the primary energy recovery section are joined only by ducts or connections carrying flue gas is not integrally designed; however, secondary energy recovery equipment (such as economizers or air preheaters) need not be physically formed into the same unit as the combustion chamber and the primary energy recovery section. The following units are not precluded from being boilers solely because they are not integral design: process heaters (units that transfer energy directly to a process stream), and fluidized bed combustion units.

(iii) While in operation, the unit maintains a thermal energy recovery efficiency of at least sixty per cent, calculated in terms of the recovered energy compared with the thermal value of the fuel.

(iv) The unit exports and utilizes at least seventy-five per cent of the recovered energy, calculated on an annual basis. In this calculation, no credit is given for recovered heat used internally in the same unit. (Examples of internal use are the preheating of fuel or combustion air, and the driving of induced or forced draft fans or feedwater pumps).

(b) The unit is one which the director has determined, on a case-by-case basis, to be a boiler, after considering the standards in 40 CFR 260.32.

(C)

(1) "CAS" means chemical abstract service.

(2) "Coal extraction" means the physical removal or exposure of ore, coal, minerals, waste rock, or overburden prior to beneficiation, and encompasses all extraction-related activities prior to beneficiation. Extraction does not include beneficiation (including coal preparation), mineral processing, in situ leaching or any further activities.

(3) "Customs territory of the United States" means the fifty states, the District of Columbia and Puerto Rico.

(D) "Disposal" means any underground injection, placement in landfills/surface impoundments, land treatment, or other intentional land disposal.

(E) "Establishment" means an economic unit, generally at a single physical location, where business is conducted or where services or industrial operations are performed.

(F)

(1) "Facility" means all buildings, equipment, structures and other stationary items which are located on a single site or on contiguous or adjacent sites and which are owned or operated by the same person (or by any person who controls, is controlled by, or under common control with such person). A facility may contain more than one establishment.

(2) "Full-time employee" means two thousand hours per year of full-time equivalent employment. A facility would calculate the number of full-time employees by totaling the hours worked during the calendar year by all employees, including contract employees, and dividing that total by two thousand hours.

(G) [Reserved.]

(H) [Reserved.]

(I)

(1) "Import" means to cause a chemical to be imported into the customs territory of the United States. For purposes of this definition, "to cause" means to intend that the chemical be imported and to control the identity of the imported chemical and the amount to be imported.

(m) Such other devices as the director may, after notice and comment, add to this list on the basis of one or more of the following:

(i) The design and use of the device primarily to accomplish recovery of material products.

(ii) The use of the device to burn or reduce raw materials to make a material product.

(iii) The use of the device to burn or reduce secondary materials as effective substitutes for raw materials, in processes using raw materials as principal feedstocks.

(iv) The use of the device to burn or reduce secondary materials as ingredients in an industrial process to make a material product

(v) The use of the device in common industrial practice to produce a material product.

(vi) Other factors, as appropriate.

Except as provided in rules 3745-100-14 and 3745-100-16 of the Administrative Code, the threshold amounts for purposes of reporting under rule 3745-100-07 of the Administrative Code for toxic chemicals are as follows:

(A) With respect to a toxic chemical manufactured (including imported) or processed at a facility during the following calendar years:

(1) 1987 - seventy-five thousand pounds of the chemical manufactured or processed for the year.

(2) 1988 - fifty thousand pounds of the chemical manufactured or processed for the year.

(3) 1989 and thereafter - twenty-five thousand pounds of the chemical manufactured or processed for the year.

(B) With respect to a chemical otherwise used at a facility, ten thousand pounds of the chemical used for the applicable calendar year.

(C) With respect to activities involving a toxic chemical at a facility, when more than one threshold applies to the activities, the owner or operator of the facility reports if the facility exceeds any applicable threshold and on all activities at the facility involving the threshold exceeding chemical, except as provided in rule 3745-100-08 of the Administrative Code.

(D) When a facility manufactures, processes, or otherwise uses more than one member of a chemical category listed by the administrator of USEPA under 40 CFR Part 372.65(c), the owner or operator of the facility reports if the facility exceeds any applicable threshold for the total volume of all the members of the category involved in the applicable activity. Any such report covers all activities at the facility involving members of the category.

(E) A facility may process or otherwise use a toxic chemical in a recycle/reuse operation. To determine whether the facility has processed or used more than an applicable threshold of the chemical, the owner or operator of the facility counts the amount of the chemical added to the recycle/reuse operation during the calendar year. In particular, if the facility starts up such an operation during a calendar year, or in the event that the contents of the whole recycle/reuse operation are replaced in a calendar year, the owner or operator of the facility also counts the amount of the chemical placed into the system at these times.

(F) A toxic chemical may be listed by the administrator of USEPA under 40 CFR Part 372.65 with the notation that only persons who manufacture the chemical, or manufacture the chemical by a certain method, are required to report. In that case, only owners or operators of facilities that manufacture that chemical as listed by the administrator of USEPA under 40 CFR Part 372.65 in excess of the threshold applicable to such manufacture in this rule and rules 3745-100-14 and 3745-100-16 of the Administrative Code are required to report. In completing the reporting form, the owner or operator is only required to account for the quantity of the chemical so manufactured and releases associated with such manufacturing, but not releases associated with subsequent processing or use of the chemical at that facility. Owners and operators of facilities that solely process or use such a chemical are not required to report for that chemical.

(G) A toxic chemical may be listed by the administrator of USEPA under 40 CFR Part 372.65 with the notation that the chemical is in a specific form (for example, fume or dust, solution, or friable) or of a specific color (for example, yellow or white). In that case, only owners or operators of facilities that manufacture, process, or use that chemical in the form or of the color specified by the administrator of USEPA under 40 CFR Part 372.65, in excess of the threshold applicable to such activity in this rule and rules 3745-100-14 and 3745-100-16 of the Administrative Code, are required to report. In completing the reporting form, the owner or operator is only required to account for the quantity of the chemical manufactured, processed, or used in the form or color specified by the administrator of USEPA under 40 CFR Part 372.65 and for releases associated with the chemical in that form or color. Owners or operators of facilities that solely manufacture, process, or use such a chemical in a form or color other than those specified by the administrator of USEPA under 40 CFR Part 372.65 are not required to report for that chemical.

(H) Metal compound categories are listed by the administrator of USEPA under 40 CFR Part 372.65(c). For purposes of determining whether any of the thresholds specified in this rule and rules 3745-100-14 and 3745-100-16 of the Administrative Code are met for the metal compound category, the owner or operator of a facility makes the threshold determination based on the total amount of all members of the metal compound category manufactured, processed, or used at the facility. In completing the release portion of the reporting form for releases of the metal compounds, the owner or operator is only required to account for the weight of the parent metal released. Any contribution to the mass of the release attributable to other portions of each compound in the category is excluded.

(A) For each toxic chemical known by the owner or operator to be manufactured (including imported), processed, or otherwise used in excess of an applicable threshold quantity in rule 3745-100-06 of the Administrative Code at its covered facility described in rule 3745-100-05 of the Administrative Code for a calendar year, the owner or operator submits a completed EPA form R (EPA form 9350-1), EPA form A (EPA form 9350-2), and, for the dioxin and dioxin-like compounds category, EPA form R Schedule 1 (EPA form 9350-3) to the Ohio EPA in accordance with the instructions in rule 3745-100-11 of the Administrative Code.

(B)

(1) The owner or operator of a covered facility reports as described in paragraph (A) of this rule on a toxic chemical that the owner or operator knows is present as a component of a mixture or trade name product which the owner or operator receives from another person, if that chemical is imported, processed, or otherwise used by the owner or operator in excess of an applicable threshold quantity in rule 3745-100-06 of the Administrative Code at the facility as part of that mixture or trade name product.

(2) The owner or operator knows that a toxic chemical is present as a component of a mixture or trade name product if one of the following is true:

(a) The owner or operator knows or has been told the chemical identity or CAS registry number of the chemical and the identity or number corresponds to an identity or number as listed by the administrator of USEPA under 40 CFR Part 372.65.

(b) The owner or operator has been told by the supplier of the mixture or trade name product that the mixture or trade name product contains a toxic chemical subject to section 313 of the act or this rule.

(3) To determine whether a toxic chemical which is a component of a mixture or trade name product has been imported, processed, or otherwise used in excess of an applicable threshold in rule 3745-100-06 of the Administrative Code at the facility, the owner or operator considers only the portion of the mixture or trade name product that consists of the toxic chemical and that is imported, processed, or otherwise used at the facility, together with any other amounts of the same toxic chemical that the owner or operator manufacturers, imports, processes, or otherwise uses at the facility as follows:

(a) If the owner or operator knows the specific chemical identity of the toxic chemical and the specific concentration at which it is present in the mixture or trade name product, the owner or operator determines the weight of the chemical imported, processed, or otherwise used as part of the mixture or trade name product at the facility and combines that with the weight of the toxic chemical manufactured (including imported), processed, or otherwise used at the facility other than as part of the mixture or trade name product. After combining these amounts, if the owner or operator determines that the toxic chemical was manufactured, processed, or otherwise used in excess of an applicable threshold in rule 3745-100-06 of the Administrative Code, the owner or operator reports the specific chemical identity and all releases of the toxic chemical on EPA form R in accordance with the instructions specified in rule 3745-100-11 of the Administrative Code.

(b) If the owner or operator knows the specific chemical identity of the toxic chemical and does not know the specific concentration at which the chemical is present in the mixture or trade name product, but has been told the upper-bound concentration of the chemical in the mixture or trade name product, the owner or operator assumes that the toxic chemical is present in the mixture or trade name product at the upper-bound concentration, and determines whether the chemical has been manufactured, processed, or otherwise used at the facility in excess of an applicable threshold as provided in paragraph (B)(3)(a) of this rule and reports as provided in paragraph (B)(3)(a) of this rule.

(c) If the owner or operator knows the specific chemical identity of the toxic chemical, does not know the specific concentration at which the chemical is present in the mixture or trade name product, has not been told the upper-bound concentration of the chemical in the mixture or trade name product, and has not otherwise developed information on the composition of the chemical in the mixture or trade name product, then the owner or operator is not required to factor that chemical in that mixture or trade name product into threshold and release calculations for that chemical.

(d) If the owner or operator has been told that a mixture or trade name product contains a toxic chemical and knows the specific concentration at which the chemical is present in the mixture or trade name product, but does not know the specific chemical identity of the chemical, the owner or operator determines the weight of the chemical imported, processed, or otherwise used as part of the mixture or trade name product at the facility. Since the owner or operator does not know the specific identity of the toxic chemical, the owner or operator makes the threshold determination only for the weight of the toxic chemical in the mixture or trade name product. If the owner or operator determines that the toxic chemical was imported, processed, or otherwise used as part of the mixture or trade name product in excess of an applicable threshold in rule 3745-100-06 of the Administrative Code, the owner or operator reports the generic chemical name of the toxic chemical, or a trade name if the generic chemical name is not known, and all releases of the toxic chemical on EPA form R and in accordance with the instructions specified in rule 3745-100-11 of the Administrative Code.

(e) If the owner or operator has been told that a mixture or trade name product contains a toxic chemical, does not know the specific chemical identity of the chemical, and does not know the specific concentration at which the chemical is present in the mixture or trade name product, but has been told the upper-bound concentration of the chemical in the mixture or trade name product, the owner or operator:

(i) Assumes that the toxic chemical is present in the mixture or trade name product at the upper-bound concentration.

(ii) Determines whether the chemical has been imported, processed, or otherwise used at the facility in excess of applicable threshold as provided in paragraph (B)(3)(d) of this rule.

(iii) Reports as provided in paragraph (B)(3)(d) of this rule.

(f) The owner or operator is not required to report with respect to a specific chemical if the following are true:

(i) The owner or operator has been told that a mixture or trade name product contains a toxic chemical.

(ii) The owner or operator does not know the specific chemical identity of the chemical.

(iii) The owner or operator does not know the specific concentration at which the chemical is present in the mixture or trade name product, including information they have themselves developed.

(iv) The owner or operator has not been told the upper-bound concentration of the chemical in the mixture or trade name product.

(C) A covered facility may consist of more than one establishment. The owner or operator of such a facility at which a toxic chemical was manufactured (including imported), processed, or otherwise used in excess of an applicable threshold may submit a separate EPA form R for each establishment or for each group of establishments within the facility to report the activities involving the toxic chemical at each establishment or group of establishments, provided that activities involving that toxic chemical at all the establishments within the covered facility are reported. If each establishment or group of establishments files separate reports, then for all other chemicals subject to reporting at that facility, a separate report is submitted. However, an establishment or group of establishments does not have to submit a report for a chemical that is not manufactured (including imported), processed, or otherwise used or released at that establishment or group of establishments.

(D) Each report under this rule for activities involving a toxic chemical that occurred during a calendar year at a covered facility shall be submitted on or before July first of the next year. The first such report was for calendar year 1988 and was due to be submitted on or before July 1, 1989.

(A) De minimis concentrations of a toxic chemical in a mixture. If a toxic chemical is present in a mixture of chemicals at a covered facility, and the toxic chemical is in a concentration in the mixture which is below one per cent of the mixture, or 0.1 per cent of the mixture in the case of a toxic chemical which is a carcinogen as defined in 29 CFR part 1910, subpart Z, a person is not required to consider the quantity of the toxic chemical present in such mixture when determining whether an applicable threshold has been met under rule 3745-100-06 of the Administrative Code or determining the amount of release to be reported under rule 3745-100-07 of the Administrative Code. This exemption applies whether the person received the mixture from another person or the person produced the mixture, either by mixing the chemicals involved or by causing a chemical reaction which resulted in the creation of the toxic chemical in the mixture. However, this exemption applies only to the quantity of the toxic chemical present in the mixture. If the toxic chemical is also manufactured (including imported), processed, or otherwise used at the covered facility other than as part of the mixture or in a mixture at higher concentrations in excess of an applicable threshold quantity set forth in rule 3745-100-06 of the Administrative Code, the person reports under rule 3745-100-07 of the Administrative Code. This exemption does not apply to toxic chemicals listed in rule 3745-100-16 of the Administrative Code, except for purposes of paragraph (D)(1) of rule 3745-100-09 of the Administrative Code.

(B) Articles. If a toxic chemical is present in an article at a covered facility, a person is not required to consider the quantity of the toxic chemical present in such article when determining whether an applicable threshold has been met under rule 3745-100-06 of the Administrative Code or determining the amount of release to be reported under rule 3745-100-07 of the Administrative Code. This exemption applies whether the person received the article from another person or the person produced the article. However, this exemption applies only to the quantity of the toxic chemical present in the article. If the toxic chemical is manufactured (including imported), processed, or otherwise used at the covered facility other than as part of the article in excess of an applicable threshold quantity set forth in rule 3745-100-06 of the Administrative Code, the person reports under rule 3745-100-07 of the Administrative Code. Persons potentially subject to this exemption should carefully review the definitions of "article" and "release" in rule 3745-100-01 of the Administrative Code. If a release of a toxic chemical occurs as a result of the processing or use of an item at the facility, that item does not meet the definition of "article."

(C) Uses. If a toxic chemical is used at a covered facility for a purpose described in paragraphs (C)(1) to (C)(5) of this rule, a person is not required to consider the quantity of the toxic chemical used for such purpose when determining whether an applicable threshold has been met under rule 3745-100-06 of the Administrative Code or determining the amount of releases to be reported under rule 3745-100-07 of the Administrative Code. However, this exemption only applies to the quantity of the toxic chemical used for the purpose described in paragraphs (C)(1) to (C)(5) of this rule. If the toxic chemical is also manufactured (including imported), processed, or otherwise used at the covered facility other than as described in paragraphs (C)(1) to (C)(5) of this rule in excess of an applicable threshold quantity set forth in rule 3745-100-06 of the Administrative Code, the person reports under rule 3745-100-07 of the Administrative Code. This exemption only applies to the quantity of the toxic chemical for the following purposes:

(1) Use as a structural component of the facility.

(2) Use of products for routine janitorial or facility grounds maintenance. Examples include use of janitorial cleaning supplies, fertilizers, and pesticides similar in type or concentration to consumer products.

(3) Personal use by employees or other persons at the facility of foods, drugs, cosmetics, or other personal items containing toxic chemicals, including supplies of such products within the facility such as in a facility-operated cafeteria, store, or infirmary.

(4) Use of products containing toxic chemicals for the purpose of maintaining motor vehicles operated by the facility.

(5) Use of toxic chemicals present in process water and noncontact cooling water as drawn from the environment or from municipal sources, or toxic chemicals present in air used either as compressed air or as part of combustion.

(D) Activities in laboratories. If a toxic chemical is manufactured, processed, or used in a laboratory at a covered facility under the supervision of a technically qualified individual as defined in rule 3745-100-01 of the Administrative Code, a person is not required to consider the quantity so manufactured, processed, or used when determining whether an applicable threshold has been met under rule 3745-100-06 of the Administrative Code or determining the amount of release to be reported under rule 3745-100-07 of the Administrative Code. This exemption does not apply in the following cases:

(1) Specialty chemical production.

(2) Manufacture, processing, or use of toxic chemicals in pilot plant scale operations.

(3) Activities conducted outside the laboratory.

(E) Certain owners of leased property. The owner of a covered facility is not subject to reporting under rule 3745-100-07 of the Administrative Code if such owner's only interest in the facility is ownership of the real estate upon which the facility is operated. This exemption applies to owners of facilities such as industrial parks, all or part of which are leased to persons who operate establishments in any SIC code or NAICS code in rule 3745-100-17 of the Administrative Code that are subject to the requirements of this part, where the owner has no other business interest in the operation of the covered facility.

(F) Reporting by certain operators of establishments on leased property such as industrial parks. If two or more persons, who do not have any common corporate or business interest (including common ownership or control), operate separate establishments within a single facility, each such person treats the establishments that person operates as a facility for purposes of this rule. The determinations in rules 3745-100-05 and 3745-100-06 of the Administrative Code are made for those establishments. If any such operator determines that the establishment is a covered facility under rule 3745-100-05 of the Administrative Code and that a toxic chemical has been manufactured (including imported), processed, or otherwise used at the establishment in excess of an applicable threshold in rule 3745-100-06 of the Administrative Code for a calendar year, the operator submits a report in accordance with rule 3745-100-07 of the Administrative Code for the establishment. For purposes of this, a common corporate or business interest includes ownership, partnership, joint ventures, ownership of a controlling interest in one person by the other, or ownership of a controlling interest in both persons by a third person.

(G) Coal extraction activities. If a toxic chemical is manufactured, processed, or otherwise used in extraction by facilities in SIC code 12, or in NAICS codes 212111, 212112 or 212113, a person is not required to consider the quantity of the toxic chemical so manufactured, processed, or otherwise used when determining whether an applicable threshold has been met under rule 3745-100-06 of the Administrative Code, or determining the amounts to be reported under rule 3745-100-07 of the Administrative Code.

(H) Metal mining overburden. If a toxic chemical that is a constituent of overburden is processed or otherwise used by facilities in SIC code 10, or in NAICS codes 212221, 212222, 212230, or 212299, a person is not required to consider the quantity of the toxic chemical so processed or otherwise used when determining whether an applicable threshold has been met under rule 3745-100-06 of the Administrative Code, or determining the amounts to be reported under rule 3745-100-07 of the Administrative Code.

(A) Except as provided in paragraphs (C), (D) and (E) of this rule, and listed by the administrator of USEPA under 40 CFR Part 372.65, a person provides written notification to each person to whom the mixture or trade name product is sold or otherwise distributed from the facility or establishment in accordance with paragraph (B) of this rule if the person owns or operates a facility or establishment which meets the following:

(1) Is in SIC codes 20 to 39 or a NAICS code that corresponds to SIC codes 20 to 39, as set forth in paragraph (B) of rule 3745-100-17 of the Administrative Code.

(2) Manufacturers (including imports) or processes a toxic chemical.

(3) Sells or otherwise distributes a mixture or trade name product containing the toxic chemical to a facility described in rule 3745-100-05 of the Administrative Code, or to a person who in turn may sell or otherwise distribute such mixture or trade name product to a facility described in paragraph (B) of rule 3745-100-05 of the Administrative Code.

(B) The written notification required in paragraph (A) of this rule includes:

(1) A statement that the mixture or trade name product contains a toxic chemical subject to the reporting requirements of Section 313 of Title III of the Superfund Amendments and Reauthorization Act of 1986 and 40 CFR Part 372.

(2) The name of each toxic chemical, and the associated CAS number of each chemical, if applicable, as listed by the administrator of USEPA under 40 CFR Part 372.65.

(3) The per cent by weight of each toxic chemical in the mixture or trade name product.

(1) For a mixture or trade name product containing a toxic chemical as listed by the administrator of USEPA under 40 CFR Part 372.65 with an effective date of January 1, 1987, the person provides the written notice described in paragraph (B) of this rule to each recipient of the mixture or trade name product with a least the first shipment of each mixture or trade name product to each recipient in each calendar year, beginning January 1, 1989.

(2) For a mixture or trade name product containing a toxic chemical as listed by the administrator of USEPA under 40 CFR Part 372.65 with an effective date of January 1, 1989 or later, the person provides the written notice described in paragraph (B) of this rule to each recipient of the mixture or trade name product with at least the first shipment of the mixture or trade name product to each recipient in each calendar year beginning with the applicable effective date.

(3) If a person changes a mixture or trade name product for which notification was previously provided under paragraph (B) of this rule by adding a toxic chemical, removing a toxic chemical, or changing the per cent by weight of a toxic chemical in the mixture or trade name product, the person provides each recipient of the changed mixture or trade name product a revised notification reflecting the change with the first shipment of the changed mixture or trade name product to the recipient.

(4) If a person discovers that a mixture or trade name product previously sold or otherwise distributed to another person during the calendar year of the discovery contains one or more toxic chemicals and that any notification provided to such other person in that calendar year for the mixture or trade name product either did not properly identify any of the toxic chemicals or did not accurately present the per cent by weight of any of the toxic chemicals in the mixture or trade name product, the person provides a new notification to the recipient within thirty days of the discovery which contains the information described in paragraph (B) of this rule, and identifies the prior shipments of the mixture or product in that calendar year to which the new notification applies.

(5) If a SDS is required to be prepared and distributed for the mixture or trade name product in accordance with 29 CFR 1910.1200, the notification is to be attached to or otherwise incorporated into such SDS. When the notification is attached to the SDS, include clear instructions that the notification shall not be detached from the SDS and that any copying and redistribution of the SDS includes copying and redistribution of the notice attached to copies of the SDS subsequently redistributed.

(D) Notifications are not required in the following instances:

(1) If a mixture or trade name product contains no toxic chemical in excess of the applicable de minimis concentration as specified in paragraph (A) of rule 3745-100-08 of the Administrative Code, except for chemicals listed by the administrator of USEPA under 40 CFR Part 372.28(a), which are excluded from the de minimis exemption.

(2) If a mixture or trade name product is one of the following:

(a) An "article" as defined in rule 3745-100-01 of the Administrative Code.

(b) Foods, drugs, cosmetics, alcoholic beverages, tobacco, or tobacco products packaged for distribution to the general public.

(c) Any consumer product, as the term is defined in the Consumer Product Safety Act contained in 15 USC 2051 to 2084, packaged for distribution to the general public.

(E) If the person considers the specific identity of a toxic chemical in a mixture or trade name product to be a trade secret under provisions of 29 CFR 1910.1200, include a generic chemical name in the notice that is descriptive of that toxic chemical.

(F) If the person considers the specific per cent by weight composition of a toxic chemical in the mixture or trade name product to be a trade secret under applicable state law or under the "Restatement of Torts" section 757, comment B, include a statement in the notice that the chemical is present at a concentration that does not exceed a specified upper-bound concentration value. For example, a mixture contains twelve per cent of a toxic chemical. However, the supplier considers the specific concentration of the toxic chemical in the product to be a trade secret. The notice would indicate that the toxic chemical is present in the mixture in a concentration of no more than fifteen per cent by weight. The upper-bound value chosen shall be no larger than necessary to adequately protect the trade secret.

(G) A person is not subject to the requirements of this rule to the extent the person does not know that the facility or establishment is selling or otherwise distributing a toxic chemical to another person in a mixture or trade name product. However, for purposes of this rule, a person has such knowledge if the person receives a notice under this rule from a supplier of a mixture or trade name product and the person in turn sells or otherwise distributes that mixture or trade name product to another person.

(H) If two or more persons who do not have any common corporate or business interest (including common ownership or control), as described in paragraph (F) of rule 3745-100-08 of the Administrative Code, operate separate establishments within a single facility, each such person shall treat the establishment each person operates as a facility for purposes of this rule. The determination under paragraph (A) of this rule is made for those establishments.

(A) Except as provided in paragraph (E) of this rule, with respect to the manufacture, process, or otherwise use of a toxic chemical, the owner or operator of a facility may apply an alternate threshold of one million pounds per year to that chemical if the owner or operator calculates that the facility would have an annual reportable amount of that toxic chemical not exceeding five hundred pounds for the combined total quantities released at the facility, disposed within the facility, treated at the facility (as represented by amounts destroyed or converted by treatment processes), recovered at the facility as a result of recycle operations, combusted for the purpose of energy recovery at the facility, and amounts transferred from the facility to off-site locations for the purpose of recycle, energy recovery, treatment, or disposal. These volumes correspond to the sum of amounts reportable for data elements on EPA form R (as referenced in paragraph (A) of rule 3745-100-11 of the Administrative Code) as part II column B or sections 8.1 (quantity released), 8.2 (quantity used for energy recovery on-site), 8.3 (quantity used for energy recovery off-site), 8.4 (quantity recycled on-site), 8.5 (quantity recycled off-site), 8.6 (quantity treated on-site), and 8.7 (quantity treated off-site).

(B) If an owner or operator of a facility determines that the owner or operator may apply the alternate reporting threshold specified in paragraph (A) of this rule for a specific toxic chemical, the owner or operator is not required to submit a report for that chemical under rule 3745-100-07 of the Administrative Code, but instead submits a certification statement that contains the information required in rule 3745-100-15 of the Administrative Code. The owner or operator of the facility shall also keep records as specified in paragraph (D) of rule 3745-100-03 of the Administrative Code.

(C) Threshold determination provisions of rule 3745-100-06 of the Administrative Code and exemptions pertaining to threshold determinations in rule 3745-100-08 of the Administrative Code are applicable to the determination of whether the alternate threshold has been met.

(D) Each certification statement under this chapter for activities involving a toxic chemical that occurred during a calendar year at a facility shall be submitted to Ohio EPA on or before July first of the next year.

(E) The provisions of this chapter do not apply to any chemicals listed in rule 3745-100-16 of the Administrative Code.
