§94.215 Maintenance of records; submittal of information; right of entry.

(a) Any manufacturer subject to any of the standards or procedures prescribed in this 

subpart shall establish, maintain and retain the following adequately organized and indexed 

records:

(1) General records. The records required to be maintained by this paragraph (a) shall 

consist of:

(i) Identification and description of all certification engines for which testing is required 

under this subpart.

(ii) A description of all emission control systems which are installed on or incorporated in 

each certification engine.

buildup activities in paragraph (a)(2)(i)(A) of this section occurred with respect to the 

certification engine and shall be kept in a designated location.

(3) All records, other than routine emission test records, required to be maintained under 

this subpart shall be retained by the manufacturer for a period of 8 years after issuance of all 

certificates of conformity to which they relate. Routine emission test records shall be retained 

by the manufacturer for a period of one (1) year after issuance of all certificates of conformity 

to which they relate. Records may be retained as hard copy or reduced to computer disks, 

etc., depending on the record retention procedures of the manufacturer: Provided, that in 

every case all the information contained in the hard copy shall be retained.

(4) Nothing in this section limits the Administrator's discretion in requiring the 

manufacturer to retain additional records or submit information not specifically required by this 

section.

(5) Pursuant to a request made by the Administrator, the manufacturer shall submit to 

him/her the information that is required to be retained.

(6) EPA may void a certificate of conformity ab initio for an engine family for which the 

manufacturer fails to retain the records required in this section or to provide such information 

to the Administrator upon request.

(b) The manufacturer of engines subject to any of the standards prescribed in this part 

shall submit to the Administrator, at the time of issuance by the manufacturer, copies of all 

instructions or explanations regarding the use, repair, adjustment, maintenance, or testing of 

such engine, relevant to the control of crankcase, or exhaust emissions issued by the 

manufacturer, for use by other manufacturers, assembly plants, distributors, dealers, owners

and operators. Any material not translated into the English language need not be submitted 

unless specifically requested by the Administrator.

(c) Any manufacturer participating in averaging, banking and trading program of subpart 

D of this part must comply with the maintenance of records requirements of §94.308.

(d)(1) Any manufacturer who has applied for certification of a new engine subject to 

certification testing under this subpart shall admit or cause to be admitted any EPA 

Enforcement Officer during operating hours on presentation of credentials to any of the 

following:
(i) Any facility where any such tests or any procedures or activities connected with such 

test are or were performed;

(ii) Any facility where any engine which is being tested (or was tested, or is to be tested) 

is present;

(iii) Any facility where any construction process or assembly process used in the 

modification or buildup of such an engine into a certification engine is taking place or has 

taken place; or

(iv) Any facility where any record or other document relating to any of the activities listed 

in this paragraph (d)(1).

(2) Upon admission to any facility referred to in paragraph (d)(1) of this section, any EPA 

Enforcement Officer shall be allowed:

(i) To inspect and monitor any part or aspect of such procedures, activities and testing 

facilities including, but not limited to, monitoring engine preconditioning, emissions tests, 

service accumulation, maintenance, and engine storage procedures, and to verify correlation 

or calibration of test equipment;

(ii) To inspect and make copies of any such records, designs, or other documents, 

including those records specified in Subpart D of this part; and

(iii) To inspect and/or photograph any part or aspect of any such certification engine and 

any components to be used in the construction thereof.

(3) In order to allow the Administrator to determine whether or not production engines, 

conform to the conditions upon which a certificate of conformity has been issued, or conform 

in all material respects to the design specifications applicable to those engines, as described 

in the application for certification for which a certificate of conformity has been issued, any 

manufacturer shall admit any EPA Enforcement Officer on presentation of credentials to:

(i) Any facility where any document, design or procedure relating to the translation of the 

design and construction of engines and emission related components described in the 

application for certification or used for certification testing into production engines is located or 

carried on;

(ii) Any facility where any engines to be introduced into commerce are manufactured; 

and

(iii) Any facility where records specified this section are located.

(4) On admission to any such facility referred to in paragraph (d)(3) of this section, any 

EPA Enforcement Officer shall be allowed:

(i) To inspect and monitor any aspects of such manufacture and other procedures;

(ii) To inspect and make copies of any such records, documents or designs;

(iii) To inspect and photograph any part or aspect of any such engine(s) and any 

component used in the assembly thereof that are reasonably related to the purpose of his/her 

entry; and

(iv) To inspect and make copies of any records and documents specified in this section.
(5) Any EPA Enforcement Officer shall be furnished by those in charge of a facility being 

inspected with such reasonable assistance as he/she may request to help him/her discharge 

any function listed in this part. Each applicant for or recipient of certification is required to 

cause those in charge of a facility operated for its benefit to furnish such reasonable 

assistance without charge to EPA whether or not the applicant controls the facility.

(6) The duty to admit or cause to be admitted any EPA Enforcement Officer applies to 

any facility involved in the manufacturing or assembling of engines, whether or not the 

manufacturer owns or controls the facility in question and applies both to domestic and to 

foreign manufacturers and facilities. EPA will not attempt to make any inspections which it has 

been informed that local law forbids. However, if local law makes it impossible to do what is 

necessary to insure the accuracy of data generated at a facility, no informed judgment that an 

engine is certifiable or is covered by a certificate can properly be based on those data. It is the 

responsibility of the manufacturer to locate its testing and manufacturing facilities in 

jurisdictions where this situation will not arise.

(7) For purposes of this section:

(i) “Presentation of credentials” shall mean display of the document designating a 

person as an EPA Enforcement Officer.

(ii) Where component or engine storage areas or facilities are concerned, “operating 

hours” shall mean all times during which personnel other than custodial personnel are at work 

in the vicinity of the area or facility and have access to it.

(iii) Where facilities or areas other than those covered by paragraph (d)(7)(ii) of this 

section are concerned, “operating hours” shall mean all times during which an assembly line is 

in operation or all times during which testing, maintenance, service accumulation, production 

or compilation of records, or any other procedure or activity related to certification testing, to 

translation of designs from the test stage to the production stage, or to engine manufacture, or 

assembly is being carried out in a facility.

(iv) “Reasonable assistance” includes, but is not limited to, clerical, copying, 

interpretation and translation services, the making available on request of personnel of the 

facility being inspected during their working hours to inform the EPA Enforcement Officer of 

how the facility operates and to answer his questions, and the performance on request of 

emissions tests on any engine which is being, has been, or will be used for certification 

testing. Such tests shall be nondestructive, but may require appropriate service accumulation. 

A manufacturer may be compelled to cause the personal appearance of any employee at such 

a facility before an EPA Enforcement Officer by written request for his appearance, signed by 

the Assistant Administrator for Air and Radiation or the Assistant Administrator for 

Enforcement and Compliance Assurance, served on the manufacturer. Any such employee 

who has been instructed by the manufacturer to appear will be entitled to be accompanied, 

represented and advised by counsel.

(v) Any entry without 24 hour prior written or oral notification to the affected 

manufacturer shall be authorized in writing by the Assistant Administrator for Air and Radiation 

or the Assistant Administrator for Enforcement and Compliance Assurance.

(8) EPA may void a certificate of conformity ab initio for engines introduced into 

commerce if the manufacturer (or contractor for the manufacturer, if applicable) fails to comply 

with any provision of this section.

§1065.25 Recordkeeping.

(a) The procedures in this part include various requirements to record data or other 

information. Refer to the standard-setting part and §1065.695 regarding specific 

recordkeeping requirements.

(b) You must promptly send us organized, written records in English if we ask for them. 

We may review them at any time.

(c) We may waive specific reporting or recordkeeping requirements we determine to be 

unnecessary for the purposes of this part and the standard-setting part. Note that while we will 

generally keep the records required by this part, we are not obligated to keep records we 

determine to be unnecessary for us to keep. For example, while we require you to keep 

records for invalid tests so that we may verify that your invalidation was appropriate, it is not 

necessary for us to keep records for our own invalid tests.

Note: Many facilities that would be affected by the rule emit GHGs from multiple sources. The facility must assess 

every source category that could potentially apply to each when determining if a threshold has been exceeded. If the 

threshold is exceed for any source category, the facility must report and keep records from emissions from all source 

categories, including those source categories that do not exceed the applicable threshold.
