whether these are substantially independent, factors such as the extent to which the new facility is

integrated with the existing plant, and the extent to which the new facility is engaged in the same

general type of activity as the existing source should be considered.

(2) Construction on a site at which an existing source is located results in a modification rather than

a new source if the construction does not create a new building, structure, facility or installation

meeting the criteria of paragraph (O)(1)(b) or (O)(1)(c) of this rule, but otherwise alters, replaces, or

adds to existing process or production equipment.

contact with any raw material, intermediate product, waste product (other than heat), or finished

product. Noncontact cooling water does not include any process waters or other type of

wastewaters, nor is it exposed to anything but the inside of the pipe. Noncontact cooling water

should be reasonably free from contaminants like metals, ammonia, organics, and total dissolved solids

so that Ohio's water quality standards in Chapter 3745-1 of the Administrative Code are not violated.

(Q) "Non-significant categorical industrial user" is an industrial user subject to 40 C.F.R. chapter I,

subchapter N that the control authority may determine is a non-significant categorical industrial user

rather than a significant industrial user on a finding that the industrial user does not discharge more

than one hundred gallons per day (gpd) of total categorical wastewater (excluding sanitary, noncontact cooling and boiler blowdown wastewater, unless specifically included in the categorical

pretreatment standard) and the following conditions are met:

(1) The industrial user, prior to the control authority's finding, has consistently complied with all

user and issues related to combined sewer overflows or sanitary sewer overflows are specifically

addressed in:

(i) The control authority's approved long term control plan;

(ii) The control authority's approved combined sewer system operation plan implementing the nine

minimum controls; or

(iii) The control authority's program modification request submitted to the director.

(R) "NPDES permit" means national pollutant discharge elimination system permit issued by the director

under the requirements of section 402 of the act, Chapter 6111. of the Revised Code, and Chapter

3745-33 of the Administrative Code.

(S) "Ohio EPA" means the Ohio environmental protection agency.

(T) "Pass through" means a discharge that exits the POTW into waters of the state in quantities or

3745-3-02 Purpose and applicability.

(A) The purpose of this chapter is to establish as part of a state pretreatment program under Chapter

6111. of the Revised Code, enforceable state requirements and standards regulating the introduction

of pollutants into POTWs by industrial users.

(B) This chapter has the following objectives:
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 7/32

(1) To prevent the introduction of pollutants into POTWs that will interfere with the operation of a

POTW, including interference with the use or disposal of its sludge;

(2) To prevent the introduction of pollutants into POTWs that will pass through the treatment works

or otherwise be incompatible with such works; and

(3) To improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges.

(C) The provisions of this chapter apply to:

(1) Pollutants from non-domestic sources covered by pretreatment standards that are indirectly

discharged into, or transported by truck or rail or otherwise introduced into, the POTWs as defined by

this chapter;

(2) POTWs that receive wastewater from sources subject to pretreatment standards; and

(3) Any new or existing source subject to pretreatment standards. Pretreatment standards do not

apply to sources connected to a sewer that is not connected to a POTW.

(D) Nothing in this chapter shall be interpreted to prevent the director or a POTW from imposing

additional or more stringent requirements or standards on any industrial user pursuant to applicable

provisions of law.

[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 rule 3745-3-01 of the Administrative Code.]

(A) Any POTW or combination of POTWs operated by the same public authority shall establish,

administer, and enforce a pretreatment program in accordance with 40 C.F.R. 403 and this rule if:

(1) The POTW or combination of POTWs has a total cumulative design flow greater than five million

gallons per day and receives, from industrial users, pollutants that pass through or interfere with the

operation of the POTW or that are otherwise subject to national pretreatment standards; or

(2) The POTW or combination of POTWs has a total design flow of five million or less gallons per day

and receives indirect discharges, if the director determines that such a program is necessary to

prevent interference or pass through. The director shall consider and base the determination on the

following:

(a) The nature or volume of the indirect discharges; or

(b) The number, nature, or frequency of violations of POTW effluent limitations contained in its NPDES

permit; or

(c) The nature, frequency, or duration of POTW treatment process upsets; or
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 8/32

(d) The actual or potential for contamination of municipal sludge; or

(e) Whether the indirect discharges are subject to categorical pretreatment standards; or

(f) Any other circumstance that causes or contributes to an interference or pass through.

(B) POTWs identified as being required to develop a POTW pretreatment program under paragraph (A)

of this rule shall develop and submit such a program for approval as soon as possible, but in no case

later than one year after written notification from the director of such identification. The POTW

pretreatment program shall meet the criteria set forth in paragraph (C) of this rule and shall be

administered by the POTW to ensure compliance by industrial users with applicable pretreatment

standards and requirements. The POTW's NPDES permit will be reissued or modified to incorporate the

approved program as an enforceable condition of the permit.

(C) A POTW pretreatment program shall be based on the following legal authority and include the

following procedures. These authorities and procedures shall at all times be fully and effectively

exercised and implemented.

(1) The POTW shall operate pursuant to legal authority, enforceable in federal, state or local courts,

that authorizes or enables the POTW to enforce the requirements of Sections 307(b), 307(c) and

402(b)(8) of the act and any regulation implementing those sections. Such authority may be

contained in a statute, ordinance, or series of contracts or joint powers agreements that the POTW is

authorized to enact, enter into or implement, and that is authorized by state law. At a minimum, this

legal authority shall enable the POTW to:

(a) Deny or condition any new or increased contribution of pollutants, or change in the nature of

pollutants, to the POTW by industrial users where such contribution does not meet applicable

pretreatment standards and requirements or where such contribution would cause the POTW to

violate its NPDES permit;

(b) Require compliance with applicable pretreatment standards and requirements by industrial users;

(c) Issue control mechanisms to control each industrial user's contribution to the POTW to ensure

compliance with applicable pretreatment standards and requirements. In the case of industrial users

identified as significant under paragraph (GG) of rule 3745-3-01 of the Administrative Code, this

control shall be achieved through individual or general control mechanisms issued to each such user or

group of users. Both individual and general control mechanisms shall be enforceable and, at a

minimum, shall include:

(i) A statement of duration (in no case more than five years);

(ii) If determined by the control authority to be transferable, a statement of transferability with, at a

minimum, prior notification to the POTW and provision of a copy of the existing control mechanism to

the new owner or operator;

(iii) Effluent limits that are based on applicable general pretreatment standards in 40 C.F.R. 403,

categorical pretreatment standards, local limits, and state and local law;

(iv) Requirements for:

(a) Self-monitoring, including an identification of the pollutants to be monitored or the process for

seeking a waiver from monitoring a pollutant neither present nor expected to be present in the
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 9/32

discharge in accordance with paragraph (C)(1)(d) of this rule, sampling location, sampling frequency,

and sample type based on the applicable general pretreatment standards in 40 C.F.R. 403, categorical

pretreatment standards, local limits, and state and local law;

(b) Reporting; and

(c) Notification and recordkeeping;

(v) A statement of applicable civil and criminal penalties for violation of pretreatment standards and

requirements, and any applicable compliance schedule. Such schedules may not extend the

compliance date beyond applicable federal deadlines;

(vi) Requirements to control slug discharges, if determined by the POTW to be necessary;

(d) Authorize, at its discretion, an industrial user subject to a categorical pretreatment standard,

except for centralized waste treatment facilities regulated by and defined in 40 C.F.R. 437, to forego

sampling of a pollutant regulated by a categorical pretreatment standard if the industrial user has

demonstrated through sampling and other technical factors that the pollutant is neither present nor

expected to be present in the discharge, or is present only at background levels from intake water

and without any increase in the pollutant due to activities of the industrial user. This authorization is

subject to the following conditions:

(i) The control authority may authorize a waiver where a pollutant is determined to be present solely

due to sanitary wastewater discharged from the facility provided that the sanitary wastewater is not

regulated by an applicable categorical standard and otherwise includes no process wastewater;

(ii) A monitoring waiver is valid only for the duration of the effective period of the permit or other

equivalent individual control mechanism, but in no case longer than five years. The industrial user shall

submit a new request for the waiver before the waiver can be granted for each subsequent control

mechanism;

(iii) In making a demonstration that a pollutant is not present, the industrial user shall provide data

from at least one sampling of the facility's process wastewater prior to any treatment present at the

facility that is representative of all wastewater from all processes. The request for a monitoring

waiver shall be signed in accordance with paragraph (F) of rule 3745-3-06 of the Administrative Code,

and include the certification statement in 40 C.F.R. 403.6(a)(2)(ii). Non-detectable sample results

may only be used as a demonstration that a pollutant is not present if the USEPA approved analytical

method from 40 C.F.R. 136 with the lowest method detection limit for that pollutant was used;

(iv) The control authority shall include any monitoring waiver as a condition in the industrial user's

control mechanism;

(v) The reasons supporting any monitoring waiver and any information submitted by the user in its

request for the waiver shall be maintained by the control authority for three years after expiration of

the waiver;

(vi) Upon approval of the monitoring waiver and revision of the industrial user's control mechanism by

the control authority, the industrial user shall certify on each periodic compliance monitoring report

required by paragraph (E) of rule 3745-3-06 of the Administrative Code with the following statement:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the

pretreatment standards under 40 C.F.R. [specify applicable national pretreatment standard part or
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 10/32

parts], I certify that, to the best of my knowledge and belief, there has been no increase in the level

of [list pollutant or pollutants] in the wastewaters due to the activities at the facility since submittal

of the last periodic report under paragraph (E) of rule 3745-3-06 of the Administrative Code."

(vii) In the event that a waived pollutant is found to be present or is expected to be present based

on changes that occur in the industrial user's operations, the user shall be required to immediately:

(a) Notify the control authority in writing; and

(b) Comply with the monitoring requirements specified in the POTW's pretreatment program;

(viii) The provision for a monitoring waiver does not relieve the industrial user of any other

certification processes and requirements established by the control authority or in categorical

pretreatment standards, except as otherwise specified in the categorical pretreatment standard;

(e) Require the development of a compliance schedule by each industrial user for the installation of

technology required to meet applicable pretreatment standards and requirements;

(f) Require the submission of all notices and self-monitoring reports from industrial users as are

necessary to assess and assure compliance by industrial users with pretreatment standards and

requirements, including but not limited to the reports required in rule 3745-3-06 of the Administrative

Code;

(g) Carry out all inspection, surveillance and monitoring procedures necessary to determine,

independent of information supplied by industrial users, compliance or noncompliance with applicable

pretreatment standards and requirements by industrial users. Representatives of the POTW shall be

authorized to enter any premises of any industrial user in which a discharge source or treatment

system is located or in which records are required to be kept under paragraph (G)(2) of rule 3745-3-

06 of the Administrative Code to assure compliance with pretreatment standards. Such authority shall

be at least as extensive as the authority provided under Section 308 of the act;

(h) Obtain remedies for noncompliance by any industrial user with any pretreatment standard or

requirement including but not limited to: the duty to allow or carry out inspections, entry, or

monitoring activities; any rules, regulations, or orders issued by the POTW; any requirements set forth

in control mechanisms issued by the POTW; or any reporting requirements imposed by the POTW or

this chapter. Remedies shall include but are not limited to the following:

(i) The POTW shall be able to seek injunctive relief for noncompliance by industrial users with

pretreatment standards and requirements. The POTW shall also have authority to seek or assess civil

or criminal penalties in at least the amount of one thousand dollars per day for each violation by

industrial users of pretreatment standards and requirements;

[Comment: The director may seek judicial relief or may also use administrative penalty authority when

the POTW has sought a monetary penalty that the director finds to be insufficient.]

(ii) The POTW shall have authority and procedures, after informal notice to the discharger,

immediately and effectively to halt or prevent any discharge of pollutants to the POTW that

reasonably appears to present an imminent endangerment to the health or welfare of persons; and

(iii) The POTW shall also have authority and procedures, that shall include notice to the affected

industrial users and an opportunity to respond, to halt or prevent any discharge to the POTW that

presents or may present an endangerment to the environment or that threatens to interfere with the
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 11/32

operation of the POTW; and

(i) Comply with the confidentiality requirements set forth in rule 3745-3-07 of the Administrative

Code.

(2) The POTW shall develop and implement procedures to ensure compliance with the requirements of

a pretreatment program. At a minimum, these procedures shall enable the POTW to:

(a) Identify all possible industrial users that may be subject to the POTW pretreatment program. Any

compilation, index or inventory of industrial users made under this paragraph shall be made available

to the director upon request;

(b) Identify the character and volume of pollutants contributed to the POTW by the industrial users

identified in paragraph (C)(2)(a) of this rule. This information shall be made available to the director

upon request;

(c) Notify industrial users identified in paragraph (C)(2)(a) of this rule of applicable pretreatment

standards and any applicable requirements under Sections 204(b) and 405 of the act and Subtitles C

and D of the Resource Conservation and Recovery Act 42 U.S.C. sections 6901 to 6992 as amended

through July 1, 2011. Within thirty days of approval of a list of significant industrial users pursuant to

paragraph (C)(6) of this rule, notify each significant industrial user of its status as such and of all

requirements applicable to it as a result of such status;

(d) Receive and analyze self-monitoring reports and other notices submitted by industrial users in

accordance with the self-monitoring requirements in rule 3745-3-06 of the Administrative Code;

(e) Randomly sample and analyze the effluent from industrial users and conduct surveillance activities

in order to identify, independent of information supplied by industrial users, occasional and continuing

noncompliance with pretreatment standards. Inspect each significant industrial user and sample the

effluent from each such user at least once a year, except as follows:

(i) Where the POTW has authorized the industrial user subject to a categorical pretreatment standard

to forego sampling of a pollutant regulated by a categorical pretreatment standard in accordance with

paragraph (C)(1)(d) of this rule, the POTW shall sample for the waived pollutant or pollutants at least

once during the term of the categorical industrial user's control mechanism. In the event that the

POTW subsequently determines that a waived pollutant is present or is expected to be present in the

industrial user's wastewater based on changes that occur in the user's operations, the POTW shall

immediately begin inspecting the user and monitoring the user's discharge at the frequency set by the

POTW's pretreatment program;

(ii) Where the POTW has determined that an industrial user meets the criteria for a non-significant

categorical industrial user, the POTW shall evaluate and document, at least once per year, whether

the industrial user continues to meet the definition in paragraph (Q) of rule 3745-3-01 of the

Administrative Code ;

(iii) In the case of mid-tier industrial users subject to reduced reporting requirements under paragraph

(E)(2) of rule 3745-3-06 of the Administrative Code, the POTW shall conduct inspections and

randomly sample and analyze the effluent from such users at least once every two years. If the

industrial user no longer meets the definition in paragraph (L) of rule 3745-3-01 of the Administrative

Code, the POTW shall immediately begin inspecting the industrial user and monitoring the effluent from

the user at the frequency set by the POTW's pretreatment program;

codes.ohio.gov/oac/3745-3 12/32

(f) Evaluate the need for a plan, device or structure to control a potential slug discharge at least

once during the term of each significant industrial user's control mechanism. Additional significant

industrial users shall be evaluated within one year of being identified a significant industrial user. For

purposes of this chapter, a slug discharge is any discharge of a non-routine, episodic nature, including

but not limited to an accidental spill or a non-customary batch discharge that has a reasonable

potential to cause interference or pass through, or in any other way violate the POTW's regulations,

local limits or permit conditions. The results of these activities shall be made available to the director

upon request. If the POTW decides that a slug control plan is needed, the plan shall contain, at a

minimum, the following elements:

(i) Description of discharge practices, including non-routine batch discharges;

(ii) Description of stored chemicals;

(iii) Procedures for immediately notifying the POTW of slug discharges, including any discharge that

would violate a prohibition under paragraph (B) of rule 3745-3-04 of the Administrative Code, with

procedures for follow-up written notification within five days;

(iv) If necessary, procedures to prevent adverse impact from accidental spills, including inspection

and maintenance of storage areas, handling and transfer of materials, loading and unloading

operations, control of wastewater discharge, worker training, building of containment structures or

equipment, measures for containing toxic organic pollutants (including solvents), or measures and

equipment for emergency response;

(g) Investigate instances of noncompliance with pretreatment standards and requirements, as

indicated in the reports and notices required under rule 3745-3-06 of the Administrative Code or

indicated by analysis, inspection, and surveillance activities described in paragraph (C)(2)(e) of this

rule. Sample taking and analysis and the collection of other information shall be performed with

sufficient care to produce evidence admissible in enforcement proceedings or in judicial actions; and

(h) Comply with the public participation requirements of 40 C.F.R. 25 in the enforcement of national

pretreatment standards. These procedures shall include provision for at least annual public

notification, in at least one newspaper of general circulation that provides meaningful public notice

within the jurisdiction served by the POTW, of industrial users that, at any time during the previous

twelve months, were in significant noncompliance with applicable pretreatment standards or other

pretreatment requirements. For the purposes of this provision, an industrial user is in significant

noncompliance if its violation meets the criteria in paragraph (C)(2)(h)(iii), (C)(2)(h)(iv), or (C)(2)(h)

(viii) of this rule. A significant industrial user is in significant noncompliance if its violation meets any

of the following criteria:

(i) Chronic violations of wastewater discharge limits, defined here as those in which sixty-six per cent

or more of all the measurements taken for the same pollutant parameter at any permitted monitoring

point during a six-month period exceed (by any magnitude) a numeric pretreatment standard or

requirement, including instantaneous limits;

(ii) Technical review criteria (TRC) violations, defined here as those in which thirty-three per cent or

more of all of the measurements taken for the same pollutant parameter at any permitted monitoring

point during a six-month period equal or exceed the product of the numeric pretreatment standard or

requirement including instantaneous limits, multiplied by the applicable TRC (TRC = 1.4 for BOD, TSS,

fats, oil and grease, and 1.2 for all other pollutants except pH);
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 13/32

(iii) Any other violation of a pretreatment standard or requirement as defined by paragraph (N) of rule

3745-3-01 of the Administrative Code (daily maximum or longer-term average, instantaneous limit, or

narrative standard) that the control authority determines has caused, alone or in combination with

other discharges, interference or pass through (including endangering the health of POTW personnel

or the general public);

(iv) Any discharge of a pollutant that has caused imminent endangerment to human health, welfare or

the environment or has resulted in the POTW's exercise of its emergency authority under paragraph

(C)(1)(h)(ii) of this rule to halt or prevent such a discharge;

(v) Failure to meet, within ninety days after the schedule date, a compliance schedule milestone

contained in a local control mechanism or enforcement order for starting construction, completing

construction, or attaining final compliance;

(vi) Failure to provide, within forty-five days after the due date, required reports such as baseline

monitoring reports, ninety day compliance reports, periodic self monitoring reports, reports on

compliance with compliance schedules, or any other reports required by the control authority;

(vii) Failure to accurately report noncompliance; or

(viii) Any other violation or group of violations, including a violation of BMPs, that the control authority

determines adversely affects the operation or implementation of the local pretreatment program.

(3) The POTW shall have sufficient resources and qualified personnel to carry out the authorities and

procedures described in paragraphs (C)(1) and (C)(2) of this rule.

(4) The POTW shall develop, update as necessary and enforce local limits that will protect the POTW

against interference and pass through. The POTW may develop BMPs and such BMPs shall be

considered local limits and pretreatment standards for the purpose of this rule.

(5) The POTW shall develop and implement an enforcement response plan. This plan shall contain

detailed procedures indicating how a POTW will investigate and respond to instances of industrial user

noncompliance. The plan shall, at a minimum:

(a) Describe how the POTW will investigate instances of noncompliance;

(b) Describe the types of escalating enforcement responses the POTW will take in response to all

anticipated types of industrial user violations and the time periods within which responses will take

place;

(c) Identify each official, including their respective title, that is responsible for each type of response;

and

(d) Discuss the POTW's primary responsibility to enforce all applicable pretreatment requirements and

standards, as detailed in paragraphs (C)(1) and (C)(2) of this rule.

(6) The POTW shall prepare and maintain a list of its industrial users meeting the criteria in paragraphs

(GG)(1) and (GG)(2) of rule 3745-3-01 of the Administrative Code. The list shall:

(a) Identify the criteria in paragraphs (GG)(1) and (GG)(2) of rule 3745-3-01 of the Administrative

Code applicable to each industrial user and, when necessary, indicate whether the POTW has made a

determination pursuant to:
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 14/32

(i) Paragraphs (Q) and (GG)(3) of rule 3745-3-01 of the Administrative Code that such industrial user

should not be considered a significant industrial user; or

(ii) Paragraph (L) of rule 3745-3-01 of the Administrative Code that such industrial user should be

considered a mid-tier categorical industrial user.

(b) Initially be submitted to the director when a POTW is applying for approval of its pretreatment

program or, in the case of POTWs with approved programs, at the time a program modification

request is submitted to provide for a non-significant categorical or mid-tier industrial user

classification. Any modification to the list shall be submitted to the director in the POTW's annual

report, pursuant to paragraph (J) of this rule.

(7) The POTW may issue a general control mechanism to a group of significant industrial users.

(a) A general control mechanism may be used for a group of significant industrial users if, in the

opinion of the POTW, the users are more appropriately controlled under a general control mechanism

than under individual control mechanisms. Each user in the group must:

(i) Have the same or substantially similar types of operations;

(ii) Discharge the same types of wastes;

(iii) Require the same effluent limitations; and

(iv) Require the same or similar monitoring.

(b) To be covered by a general control mechanism, the significant industrial user shall be required to

file a written request for coverage that identifies its contact information, its production processes,

the types of wastes generated, the location for monitoring all wastes covered by the general control

mechanism, any requests in accordance with paragraph (C)(1)(d) of this rule for a monitoring waiver

for a pollutant neither present nor expected to be present in the discharge, and any other information

the POTW deems appropriate. A monitoring waiver for a pollutant neither present nor expected to be

present in the discharge is not effective in the general control mechanism until the POTW has

provided written notice to the significant industrial user that a waiver request has been granted in

accordance with paragraph (C)(1)(d) of this rule.

(c) The POTW shall retain a copy of the general control mechanism, documentation to support the

POTW's determination that a specific significant industrial user meets the criteria in paragraphs (C)(7)

(a)(i) to (C)(7)(a)(iv) of this rule, and a copy of the user's written request for coverage for three

years after the expiration of the general control mechanism.

(d) The POTW shall not control a significant industrial user through a general control mechanism

where the user is subject to production-based categorical pretreatment standards or categorical

pretreatment standards expressed as mass of pollutant discharged per day or for industrial users

whose limits are based on the combined wastestream formula or net/gross calculations in 40 C.F.R.

403.6(e) and 40 C.F.R. 403.15.

(D) POTW pretreatment program submission.

(1) A POTW requesting approval of a POTW pretreatment program shall develop a program description

submitted to the director who will make a determination on the request for program approval in
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 15/32

accordance with the procedures described in 40 C.F.R. 403.11.

(2) The program description shall contain, at a minimum, the following information:

(a) A statement from the city solicitor or a city official acting in a comparable capacity (or the

attorney for those POTWs that have independent legal counsel) that the POTW has authority

adequate to carry out the programs described in paragraphs (A), (B), and (C) of this rule. This

statement shall:

(i) Identify the provision of the legal authority under paragraph (C)(1) of this rule that provides the

basis for each procedure under paragraph (C)(2) of this rule;

(ii) Identify the manner in which the POTW will implement the program requirements set forth in

paragraphs (A), (B), and (C) of this rule, including the means by which pretreatment standards will be

applied to individual industrial users (e.g., by permit); and

(iii) Identify how the POTW intends to ensure compliance with pretreatment standards and

requirements, and to enforce them in the event of noncompliance by industrial users;

(b) A copy of any statutes, ordinances, regulations, agreements, or other authorities relied upon by

the POTW for its administration of the program. This submission shall include a statement reflecting

the endorsement or approval of the local boards or bodies responsible for supervising and funding the

POTW pretreatment program if approved;

(c) A brief description of the POTW organization, including an organization chart, that will administer

the pretreatment program. If more than one agency is responsible for administration of the program

the responsible agencies should be identified, their respective responsibilities should be delineated,

and their procedures for coordination should be set forth; and

(d) A description of the funding levels and full-and part-time manpower available to implement the

program.

(E) Modification of POTW pretreatment programs. Either the director or a POTW with an approved

pretreatment program may initiate program modification at any time to reflect changing conditions at

the POTW. Program modification is necessary whenever there is a significant change in the operation

of a POTW pretreatment program that differs from the information in the POTW's submission, as

approved under 40 C.F.R. 403.11.

(1) The POTW shall submit a pretreatment program modification request to the director for any

modification to its pretreatment program at least forty-five days prior to when it is to be implemented

by the POTW.

(a) A pretreatment program modification request shall, at a minimum, contain the following:

(i) A statement of the basis for the desired modification;

(ii) A modification program submittal, which shall include the existing portions of the program and the

proposed changes; and

(iii) Any other documents the director determines to be necessary.

obtain the director's approval prior to the implementation of the modification. The director shall
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 16/32

determine if a modification request is nonsubstantial or substantial based on the criteria in paragraph

(E)(2) of this rule. When approving or disapproving a modification request, the director shall follow the

procedures in paragraphs (F) and (G) of this rule.

(2) Substantial modifications include:

(a) Any modification that makes the POTW's legal authorities, as described in paragraph (C) of this

rule, less stringent than they were prior to the modification, except for modifications that constitute

changes to an approved pretreatment program and are reported as nonsubstantial modifications

pursuant to paragraph (G) of this rule;

(b) Any modification that makes the POTW's local limits less stringent than they were prior to the

modification, except for the modifications to local limits for pH and the reallocation of the maximum

allowable industrial loading of a pollutant that does not increase the total industrial loading of the

pollutant, that are reported pursuant to paragraph (G) of this rule. Maximum allowable industrial

loading means the total mass of a pollutant that all industrial users of a POTW or a subgroup of

industrial users identified by the POTW may discharge pursuant to limits developed under paragraph

(C) of this rule;

(c) Any change to the POTW's control mechanism, as described in paragraph (C)(1)(c) of this rule;

(L) of rule 3745-3-01 of the Administrative Code; or

(j) Any other modification designated as a substantial modification by the director on the basis that

the modification could:

(i) Have a significant impact on the operation of the POTW's pretreatment program;

(ii) Result in an increase in pollutant loadings at the POTW; or

(iii) Result in less stringent requirements being imposed on industrial users of the POTW.

(F) Approval procedures for substantial modifications.

(1) Except as provided in paragraphs (F)(2) and (F)(3) of this rule, the director shall approve or

disapprove the modification based on the requirements of paragraph (C) of this rule and using the

procedures in paragraphs (b) to (f) of 40 C.F.R. 403.11. The modification shall become effective upon

approval by the director.

(2) The director need not publish a notice of decision under paragraph (e) of 40 C.F.R. 403.11
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 17/32

provided: the notice of request for approval under paragraph (b)(1) of 40 C.F.R. 403.11 states that

the request will be approved if no comments are received by a date specified in the notice; no

substantive comments are received; and the request is approved without change.

(3) Notices required by 40 C.F.R. 403.11 may be performed by the POTW provided that the POTW

notice otherwise satisfies the requirements of 40 C.F.R. 403.11.

(G) Approval procedures for nonsubstantial modifications.

(1) The POTW shall notify the director of any nonsubstantial modification at least forty-five days prior

to implementation by the POTW in accordance with the provisions of paragraph (E)(1) of this rule.

(2) If the director does not notify the POTW within forty-five days of its decision to approve or deny

the modification, or to treat the modification as substantial under paragraph (E)(2) of this rule, the

POTW may implement the modification.

(H) All program modifications shall be incorporated into the POTW's NPDES permit or NPDES permits

upon approval.

(I) The director may revoke a POTW's pretreatment program prescribed under paragraphs (A) and (B)

of this rule if the director determines that such a program is no longer necessary. Prior to revoking a

program, the director shall consider and base the determination on the following:

(1) The nature or volume of indirect discharges;

(2) The number, nature, or frequency of violations of POTW effluent limitations contained in its NPDES

permit;

(3) The nature, frequency, or duration of POTW treatment process upsets;

(4) The actual or potential for contamination of municipal sludge;

(5) Whether the indirect discharges are subject to categorical pretreatment standards; and

(6) Any other circumstance that causes or contributes to an interference or a pass through.

(J) Any POTW that has a pretreatment program shall provide the director with a report that describes

the POTW's program activities, including activities of all participating agencies if more than one

jurisdiction is involved in the local program. The report required by this paragraph shall be submitted

to the director annually as specified in the POTW's NPDES permit. The report shall contain such

information as the director deems necessary.

(K) No POTW shall authorize or otherwise allow an industrial user to discharge pollutants to the POTW

in violation of pretreatment standards established in this chapter. This provision shall not be

interpreted to prevent a POTW from adopting or enforcing a pretreatment standard that is more

stringent than provided in this chapter.

(L) Any POTW to which reports are submitted by an industrial user pursuant to rule 3745-3-06 of the

Administrative Code shall retain such reports for a minimum of three years and shall make such reports

available for inspection and copying by the director . This period of retention shall be extended during

the course of any unresolved litigation regarding an industrial user's discharge or the POTW's NPDES

permit or pretreatment program.

(M) Industrial user permits to install. The director may authorize a municipal corporation, county, or

special district that owns or operates a POTW or sewerage system that has an approved

pretreatment program to review and take final action on industrial permits to install for indirect

discharges by industrial users of its treatment works or sewerage system.

(1) In performing the review and final action on permits to install for indirect discharges by industrial

users of its treatment works or sewerage system, the municipal corporation, county, or special

district shall apply criteria and procedures specified by the director. This provision shall not be

interpreted to prevent a municipal corporation, county, or special district from applying criteria or

procedures that are more stringent than specified by the director.

(2) A municipal corporation, county, or special district that owns or operates a POTW or sewerage

system that has an approved pretreatment program requesting authorization to review and take final

action on industrial permits to install for indirect discharges by industrial users of its treatment works

or sewerage system shall submit the request in accordance with the procedures described in

paragraph (E) of this rule. Information to be submitted with the request shall be determined by the

director.

(3) The director may periodically evaluate the review performed by the municipal corporation, county,

or special district that has received authorization from the director to review and take final action on

permits to install under paragraph (M) of this rule and may terminate such authorization for poor

quality review, or for failure to apply rules, criteria or procedures specified by the director.

organizations and associations, federal rules and federal statutory provisions referenced in this rule,

see rule 3745-3-01 of the Administrative Code.]

(A) Reserved.

(B) Baseline report.

(1) Within one hundred eighty days after the effective date of a national categorical pretreatment

standard, or one hundred eighty days after the final administrative decision made upon a category

determination submission under paragraph (H) of rule 3745-3-09 of the Administrative Code,

whichever is later, existing industrial users subject to such categorical standard or standards and

currently discharging to or intending to discharge to a POTW shall submit to the control authority a

baseline report which contains the information listed in paragraphs (C)(1) to (C)(6) of this rule, at

least ninety days prior to commencement of discharge. New sources, and sources that become

industrial users subsequent to the promulgation of an applicable categorical standard, shall be

required to submit to the control authority a report which contains the information listed in

paragraphs (C)(1) to (C)(5) of this rule. New sources shall also be required to include in this report

information on the method of pretreatment the source intends to use to meet applicable pretreatment

standards. New sources shall give estimates of the information requested in paragraphs (C)(4) and

(C)(5) of this rule.

(2) Where the industrial user's categorical pretreatment standard has been modified by a removal

allowance or the combined wastestream formula under paragraph (I)(1) of rule 3745-3-09 of the

Administrative Code, at the time the user submits its baseline report the information required by

paragraphs (C)(5) and (C)(6) of this rule shall pertain to the modified limits.

cycles and expected pollutant discharges to the POTW.

(C) The baseline report required by paragraph (B) of this rule shall contain the following information:

(1) The name and address of the facility including the name of the operator and owners;

(2) A list of any environmental control permits held by or for the facility;

(3) A brief description of the nature, average rate of production, and standard industrial classification

of the operation carried out by such industrial users. This description shall include a schematic

process diagram which indicates points of discharge to the POTW from the regulated processes;

(4) Information showing the measured average daily and maximum daily flow, in gallons per day, to

the POTW from each of the following:

(a) Regulated process streams; and

(b) Other streams as necessary to allow use of the combined wastestream formula of 40 C.F.R. 403.6.

The control authority may allow for verifiable estimates of these flows where justified by cost or

feasibility considerations.

(5) The results of sampling and analysis identifying the nature and concentration (or mass, where

required by the standard or control authority) of regulated pollutants in the discharge from each

regulated process. Both daily maximum and average concentration (or mass, where required) shall be

reported. The sample shall be representative of daily operations. In cases where the standard requires

compliance with a BMP or a pollution prevention alternative, the industrial user shall submit

documentation as required by the control authority or the applicable standards to determine

compliance with the standard;

(6) A statement, reviewed and signed by an authorized representative of the industrial user (as

defined in paragraph (F) of this rule), certifying whether categorical pretreatment standards are being

met on a consistent basis, and, if not, whether additional operation and maintenance or additional

pretreatment or both, is required by the industrial user to meet the categorical pretreatment

standards and requirements; and

(7) If additional pretreatment operation and maintenance, or both, will be required to meet the

categorical pretreatment standards, the shortest schedule by which the industrial user will provide
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 22/32

such additional measures.

(8) The schedule required by paragraph (C)(7) of this rule shall contain increments of progress in the

form of dates for the commencement and completion of major events leading to the construction and

operation of additional pretreatment required for the industrial user to meet the applicable categorical

pretreatment standards (e.g., hiring an engineer, completing preliminary plans, completing final plans,

executive contract for major components, commencing construction, completing construction, etc).

No increment shall exceed nine months.

(9) Not later than fourteen days following each date in the schedule required by paragraph (C)(7) of

this rule and the date for final compliance with the applicable categorical pretreatment standard or

standards, the industrial user shall submit a progress report to the control authority including, at a

minimum, whether or not it complied with the increment of progress to be met on such date and, if

not, the date on which it expects to comply with this increment of progress, the reason for delay,

and the steps being taken by the industrial user to return the construction to the schedule

established. In no event shall more than nine months elapse between such progress reports to the

control authority.

(D) Initial compliance report.

Within ninety days following the date for final compliance with applicable categorical pretreatment

standards or, in the case of a new source, following commencement of the introduction of

wastewater into the POTW, any industrial user subject to categorical pretreatment standards shall

submit to the control authority a report containing the information described in paragraphs (C)(4) to

(C)(6) of this rule. For industrial users subject to equivalent mass or concentration limits established

by the control authority in accordance with the procedures in paragraph (I) of rule 3745-3-09 of the

Administrative Code, this report shall contain a reasonable measure of the user's long-term production

rate. For all other industrial users subject to categorical pretreatment standards expressed in terms of

allowable pollutant discharge per unit of production (or other measure of operation), this report shall

include the user's actual production during the appropriate sampling period.

(E) Periodic compliance monitoring reports.

(1) Industrial users subject to categorical pretreatment standards, except a non-significant

categorical user as defined in paragraph (Q) of rule 3745-3-01 of the Administrative Code, after the

compliance date of such pretreatment standard, or, in the case of a new source, after

commencement of the discharge into the POTW, shall submit a periodic compliance monitoring report

to the control authority during the months of June and December, unless required more frequently or

during different months by the categorical pretreatment standard or the control authority.

(2) For a mid-tier categorical industrial user as defined in paragraph (L) of rule 3745-3-01 of the

Administrative Code, the control authority may reduce the frequency for reporting specified in

paragraph (E)(1) of this rule to no less than once a year, unless required more frequently in the

pretreatment standard or by the director, when the following conditions are met:

(a) The industrial user shall notify the control authority immediately of any changes at its facility

causing it to no longer meet conditions in paragraph (L) of rule 3745-3-01 of the Administrative Code.

Upon notification, the industrial user shall immediately begin complying with the minimum reporting

requirement specified in the POTW's pretreatment program; and

(b) The control authority shall retain documentation to support its determination that an industrial
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 23/32

user meets the definition of a mid-tier categorical industrial user in paragraph (L) of rule 3745-3-01 of

the Administrative Code for a period of three years after the expiration of the control mechanism.

(3) For categorical industrial users subject to categorical standards for electroplating ( 40 C.F.R. Part

413 ), metal finishing ( 40 C.F.R. Part 433 ), and electrical and electronic component manufacturing (

40 C.F.R. Part 469 ), in lieu of requiring monitoring for total toxic organics (TTOs) the control

authority may allow for implementation of a certified total toxic organics management plan (TOMP).

(a) To implement this option, a TOMP shall be submitted to the control authority for review and

approval and shall include the following information. If requested information is not applicable, an

explanation shall be included in the plan.

(i) A complete inventory of all toxic organic chemicals used, generated, stored or identified through

sampling and analysis of the wastewater from regulated process operations. A listing of regulated

name products must be obtained from the supplier.

(ii) The identities and determinations or best estimates of approximate maximum quantities of toxic

organic pollutants used in and discharged from the regulated processes. Compounds present in the

wastestreams that are discharged to sanitary sewers or surface waters may be a result of regulated

processes or disposal, spills, leaks, rinse waters carryover, air pollution control, and other sources.

(iii) A pollution prevention assessment for TTOs. This includes an assessment of pollution prevention

options that could be implemented to minimize or eliminate the discharge of toxic organics introduced

into the wastestream under current and future conditions.

(a) Pollution prevention options include, but are not limited to, the following:

(i) Material substitution;

(ii) Improved operating practices;

(iii) Technology changes; and

(iv) Recycling.

(b) Once pollution prevention options are identified, a technical and economic evaluation of viable

options shall be conducted to select options, or projects that are technically and economically viable.

A schedule of implementation shall be developed and a measurement system to track the

implementation progress of the pollution prevention options shall be developed and revised as

necessary.

(iv) A description of the methods of disposal other than discharge to wastewaters, such as

reclamation, contract hauling, or incineration. A detailed description for each waste shall be included

with information on how the waste is stored prior to disposal.

(v) The procedures for ensuring that the regulated toxic organic pollutants do not spill or routinely

leak into process wastewaters, floor drains, noncontact cooling water, groundwater, surface waters,

sanitary sewers or any other location which allows the discharge of the compounds. These

procedures shall include, but are not limited to, the following:

(a) A description of the practices to be followed, including housekeeping procedures, during the use,

paragraph (E)(3)(b)(iii) of this rule must be described;

(v) A flow schematic showing all of the sources and pathways where toxic organics could enter the

wastestream shall be provided;

(vi) The approximate quantities of each toxic organic chemical used at each step in the regulated

process must be listed; and

(vii) Evaluate any regulated TTO found in the effluent, but not on the TTO inventory list required in

paragraph (E)(3)(a)(i) of this rule and determine if the TTOs are formed as reaction products or byproducts or from raw materials, impurities, equipment corrosion or other sources.

(c) Certification eligibility. In order to qualify for the alternative in paragraph (E)(3) of this rule, the

following criteria shall be met:

(i) The baseline analysis must show compliance with the appropriate TTO standards;

(ii) An acceptable TOMP must be submitted; and

(iii) The following certification statement must be signed by an officer of the company or manager

responsible for overall plant operations, and submitted with the TOMP and each subsequent periodic

compliance report:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the

standard for total toxic organics (TTO), I certify that, to the best of my knowledge and belief, no

discharge or dumping of concentrated toxic organics into the wastewaters has occurred since filing

the last discharge monitoring report. I further certify that this facility is implementing the toxic

organic management plan submitted to the control authority".

(d) The control authority shall be notified if any production process is modified or if conditions change

that affect the use or storage of toxic organics. The control authority may require that additional

sampling be performed.

(e) Certification re-evaluation. At least every permit cycle but no longer than five years, the TOMP

shall be updated and the regulated wastestream shall be sampled and analyzed for the required TTOs,

or those toxic organic compounds expected to be present, unless the control authority has performed

the required sampling in lieu of the facility. Industries in the electrical and electronic component

manufacturing category must sample for all toxic organics included on the list in 40 C.F.R. 469.

(f) Revocation of certification eligibility. The certification eligibility may be revoked if independent

sampling reveals violations or results inconsistent with the values reported by the entity for other

cause.

(g) TTO monitoring shall resume upon the end or revocation of certification.

(4) The periodic compliance monitoring report shall include the following:

(a) A report indicating the nature and concentration of pollutants in the discharge that are limited by

such categorical pretreatment standards;

the discharge to the POTW, reporting the same information as called for under paragraph (C)(4) of
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 26/32

this rule unless the control authority should require more detailed reporting of flows;

(c) Where the control authority has imposed mass limitations on industrial users, the mass of

pollutants in the discharge from the industrial user relevant to such mass limitations;

(d) For industrial users subject to equivalent mass or concentration limits established by the control

authority, a reasonable measure of the user's long-term production rate;

(e) For industrial users subject to categorical pretreatment standards expressed only in terms of

allowable pollutant discharge per unit of production (or other measure of operation), the user's actual

average production rate for the reporting period; and

(f) In cases where the pretreatment standard requires compliance with a BMP or a pollution

prevention alternative, documentation required by the control authority or the pretreatment standard

necessary to determine the compliance status of the user.

(5) The control authority shall require appropriate reporting from those industrial users with discharges

that are not subject to categorical pretreatment standards. Significant noncategorical industrial users

shall submit to the control authority at least once every six months (on dates specified by the control

authority) a description of the nature, concentration, and flow of the pollutants required to be

reported by the control authority. In cases where a local limit requires compliance with a BMP or a

pollution prevention alternative, the user shall submit documentation required by the control authority

to determine the compliance status of the user.

(F) The reports and certifications required by this rule shall include the certification statement in 40

C.F.R. 403.6(a)(2)(ii) and shall be signed by an authorized representative of the industrial user. An

authorized representative may be:

(1) A responsible corporate officer, if the industrial user submitting the reports required by this rule is

a corporation. For the purpose of this paragraph, a "responsible corporate officer" means:

(a) A president, secretary, treasurer, or vice president of the corporation in charge of a principal

business function, or any other person who performs similar policy- or decision-making functions for

the corporation; or

(b) The manager of one or more manufacturing, production, or operation facilities, provided the

manager:

(i) Is authorized to make management decisions that govern the operation of the regulated facility,

including having the explicit or implicit duty of making major capital investment recommendations, and

of initiating and directing other comprehensive measures, to assure long-term environmental

compliance with environmental laws and regulations;

(ii) Can ensure that the necessary systems are established or that the necessary actions are taken

to gather complete and accurate information for control mechanism requirements; and

(iii) Is assigned or delegated the authority to sign documents in accordance with corporate

procedures.

(2) A general partner or proprietor if the industrial user submitting the report is a partnership or sole

proprietorship, respectively.
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 27/32

(3) A member or manager if the industrial user submitting the report is a limited liability company;

(4) A duly authorized representative of the individual designated in paragraph (F)(1), (F)(2) or (F)(3)

of this rule if:

(a) The authorization is made in writing by the individual described in paragraph (F)(1), (F)(2) or (F)

(3) of this rule;

(b) The authorization specifies either an individual or a position having responsibility for the overall

operation of the facility from which the industrial discharge originates, such as the position of plant

manager, or a position of equivalent responsibility, or having overall responsibility for environmental

matters for the company; and

(c) The written authorization is submitted to the control authority.

(5) If an authorization under paragraph (F)(4) of this rule is no longer accurate because a different

individual or position has responsibility for the overall operation of the facility, or overall responsibility

for environmental matters for the company, a new authorization satisfying the requirements of

paragraph (F)(4) of this rule shall be submitted to the control authority prior to or together with any

reports to be signed by an authorized representative.

(G) Any industrial user subject to the reporting requirements established in this rule shall:

(1) Maintain records of all information resulting from any monitoring activities required by this rule.

Such records shall include for all samples:

(a) The date, exact place, method, and time of sampling and the names of the person or persons

taking the samples;

(b) The dates analyses were performed;

(c) Who performed the analyses;

(d) The analytical techniques or methods used; and

(e) The results of such analyses; and

(2) Retain, for a minimum of three years, any records of monitoring activities and results (whether or

not such monitoring activities are required by this rule) and shall make such records available for

inspection and copying by Ohio EPA, USEPA, or the POTW to which the industrial user discharges.

This period of retention shall be extended during the course of any unresolved litigation regarding the

industrial user or when requested by the director.

(H) Sampling and analysis performed in preparation of any report required by this rule shall be

conducted in accordance with the following requirements:

(1) For the reports required in paragraphs (B) and (D) of this rule, a minimum of four grab samples

shall be used for pH, hexavalent chromium, cyanide, total phenols, oil and grease, sulfide, and volatile

organics for facilities for which historical sampling data do not exist; for facilities for which historical

sampling data are available, the control authority may authorize a lower minimum. For all other

pollutants, twenty-four-hour composite samples shall be obtained through flow-proportional composite

sampling techniques, unless flow-proportional sampling is waived by the control authority. In such

cases, samples may be obtained through time-proportional composite sampling techniques or through
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 28/32

a minimum of four grab samples where the user demonstrates that this will provide a representative

sample of the effluent being discharged;

(2) For those reports required in paragraphs (B) and (D) of this rule, unless an alternate sampling

procedure is specified by the control authority, where the flow of the stream being sampled is less

than or equal to nine hundred fifty thousand liters per day (approximately two hundred fifty thousand

gallons per day), the user shall take three samples within a two-week period; where the flow of the

stream being sampled is greater than nine hundred fifty thousand liters per day, the user shall take six

samples within a two-week period;

(3) Samples should be taken immediately downstream from pretreatment facilities, if such exist, or

immediately downstream from the regulated process if no pretreatment exists. If other wastestreams

are mixed with the regulated wastewater prior to pretreatment, the user should measure the flows

and concentrations necessary to allow use of the combined wastestream formula under paragraph (I)

(1) of rule 3745-3-09 of the Administrative Code in order to evaluate compliance with the categorical

pretreatment standards;

(4) Except as otherwise provided in this rule, sampling and analysis shall be performed in accordance

with the techniques prescribed in 40 C.F.R. 136. Where 40 C.F.R. 136 does not contain sampling or

analytical techniques for the pollutant in question, or where the director determines that the 40

C.F.R. 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling

and analysis shall be performed by using analytical methods or other applicable sampling and analytical

procedures approved by the director;

(5) Except in the case of non-significant categorical industrial users, the sampling and analysis

required in paragraphs (B), (D), and (E) of this rule may be performed by the control authority in lieu

of the industrial user. Where the POTW performs the required sampling and analysis in lieu of the

industrial user, the user will not be required to submit the compliance certification required in

paragraph (C)(6) of this rule. In addition, where the POTW itself collects all the information required

for the report, including flow data, the industrial user will not be required to submit the report;

(6) If sampling performed by an industrial user indicates a violation, the user shall notify the control

authority within twenty-four hours of becoming aware of the violation. The user shall also repeat the

sampling and analysis and submit the results of the repeat analysis to the control authority within

thirty days after becoming aware of the violation. Where the control authority has performed the

sampling and analysis in lieu of the industrial user, the control authority shall perform the repeat

sampling and analysis unless it notifies the user of the violation and requires the user to perform the

repeat analysis. Resampling is not required if:

(a) The control authority performs sampling at the industrial user at a frequency of at least once per

month, or

(b) The control authority performs sampling at the user between the time when initial sampling was

conducted and the time when the results of the initial sampling are received;

(7) The reports required in paragraph (E) of this rule shall be based upon data obtained through

appropriate sampling and analysis performed during the period covered by the report, which data is

representative of conditions occurring during the reporting period. The control authority shall require

that frequency of monitoring necessary to assess and assure compliance by industrial users with

applicable pretreatment standards and requirements. Grab samples shall be used for pH, hexavalent
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 29/32

chromium, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. For all other

pollutants, twenty-four-hour composite samples shall be obtained through flow-proportional composite

sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by

the control authority. Where time-proportional composite sampling or grab sampling is authorized by

the control authority, the samples shall be representative of the discharge and the decision to allow

the alternative sampling shall be documented in the industrial user file for that facility or facilities.

Using protocols (including appropriate preservation) specified in 40 C.F.R. 136 and appropriate USEPA

guidance, multiple grab samples collected during a twenty-four-hour period may be composited prior

to the analysis as follows: for hexavalent chromium, cyanide, total phenols, and sulfides the samples

may be composited in the laboratory or in the field; for volatile organics and oil and grease the

samples may be composited in the laboratory. Composite samples for other parameters unaffected by

the compositing procedures as documented in approved USEPA methodologies may be authorized by

the control authority, as appropriate;

(8) For the reports required by paragraph (E) of this rule, the control authority shall require the

number of grab samples necessary to assess and assure compliance by industrial users with applicable

pretreatment standards and requirements;

(9) If an industrial user subject to the reporting requirement in paragraph (E) of this rule monitors any

regulated pollutant at the permitted sampling location more frequently than required by the control

authority, using the procedures described in paragraph (H)(4) of this rule, the results of this

monitoring shall be included in the report; and

(10) The control authority may require an industrial user to install flow monitoring facilities,

instruments, and recording devices to enable accurate measurement of flows as determined to be

necessary.

(I) All industrial users shall promptly notify the control authority and the POTW in the cases where the

POTW does not have an approved pretreatment program in advance of any substantial change in the

volume or character of pollutants in their discharge including the listed or characteristic hazardous

wastes for which the industrial user has submitted initial notification under 40 C.F.R. 403.12(p).

Significant industrial users shall notify the POTW immediately of any changes at its facility affecting

potential for a slug discharge.

(J) Annual certification by non-significant categorical industrial users. A facility determined to be a

non-significant categorical industrial user pursuant to paragraph (Q) of rule 3745-3-01 of the

Administrative Code shall annually submit the following certification statement, signed in accordance

with the signatory requirements in paragraph (F) of this rule. This certification shall accompany any

alternative report required by the POTW:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the

categorical pretreatment standards under 40 C.F.R. [specify applicable national pretreatment

standard part or parts], I certify that, to the best of my knowledge and belief, during the period from

[specify month, day and year] to [specify month, day and year]:

(1) "The facility described as [insert facility name] met the definition of a non-significant categorical

industrial user as described in paragraph (Q) of rule 3745-3-01 of the Administrative Code;

(2) "The facility complied with all applicable pretreatment standards and requirements during this

reporting period; and
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 30/32

(3) "The facility never discharged more than one hundred gallons of total categorical wastewater on

any given day during this reporting period. This compliance certification is based upon the following

information:_[specify information]."

3745-3-09 General requirements governing application of pretreatment standards.

[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 rule 3745-3-01 of the Administrative Code.]

(A) The provisions of this rule provide general requirements concerning the application of

pretreatment standards to industrial users.

(B) Industrial users subject to categorical pretreatment standards shall also comply with the limits

under rule 3745-3-04 of the Administrative Code - "Prohibited discharges," and with any more

stringent pretreatment standards applicable under an approved POTW pretreatment program.

(C) Existing sources that become industrial users subsequent to promulgation of an applicable national

categorical pretreatment standard shall be considered existing industrial users except where such

sources meet the definition of a new source as defined in rule 3745-3-01 of the Administrative Code.

(D) New sources shall comply with the pretreatment standard for new sources (PSNS) that is

specified in the applicable subcategory of the national categorical pretreatment standard.

(E) Except where expressly authorized to do so by an applicable pretreatment standard or

requirement, no industrial user shall ever increase the use of process water or, in any other way,

attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve

compliance with a pretreatment standard or requirement. The director or a POTW under an approved

POTW pretreatment program may impose mass limitations on industrial users that are using, or

attempt to use, dilution to meet applicable pretreatment standards or requirement, or in such other

cases where the imposition of mass limitations is appropriate.

(F) Pollutant discharge limits in categorical pretreatment standards are expressed either as

concentration or mass limits or both. Wherever possible, equivalent mass limits are provided, and the

director or a POTW may use either concentration or mass limits for enforcement purposes. Limits in

categorical pretreatment standards shall apply to the effluent of the process regulated by the

standard, or as otherwise specified by the standard.

(G) Unless otherwise provided in an applicable categorical pretreatment standard, compliance with

such standards shall be measured in accordance with the methods of analyses and sampling

procedures specified under rule 3745-3-06 of the Administrative Code.

(H) In all cases in which a determination is sought by an industrial user concerning the applicability of

a particular subcategory under the national categorical pretreatment standards, the final

determination issued under 40 C.F.R. 403.6 shall control the application of the appropriate

subcategory. There shall be no right or procedure implied under this chapter for industrial users or

POTWs to seek such categorical determinations from the director other than through the procedures

and within the requirements of 40 C.F.R. 403.6.

(I)
10/31/13 Lawriter - OAC

codes.ohio.gov/oac/3745-3 32/32

(1) National categorical pretreatment standards shall apply to an industrial user unless an enforceable

alternative limit to the standard is applicable to the industrial user under:

(a) 40 C.F.R. 403.7 (removal credits) to reflect the removal at a POTW of pollutants discharged by

the industrial user of pollutants;
