United States Environmental Protection Agency Compliance Requirements
(Stationary Emergency Spark-Ignited Generators)
Purchaser's/Owner's Record Keeping Responsibilities
The United States Environmental Protection Agency (EPA) and Generac Power Systems, Inc. (Generac) are pleased to explain your record
keeping requirements for compliance with Subpart JJJJ- Standards of Performance for Stationary Spark Ignition Internal Combustion
Engines as listed in the Electronic Code of Federal Regulations Title 40 Part 60. As the engine purchaser/owner who operates and maintains
their certified emergency stationary engine and emission control system according to applicable emission related guidelines as specified in
this Owner's Manual, you are required to meet the following notification and record keeping requirements to demonstrate compliance: 1)
Maintain documentation that the engine is certified to meet emission standards. 2) Record keeping of maintenance conducted. 3) Record
keeping of the provision allowing natural gas engines to operate using propane for a maximum of 100 hours per year as an alternate fuel
solely during emergency operations provided the engine is not certified to operate on propane. 4) Meet all compliance notifications submitted
to the purchaser/owner and maintain all supporting documentation. 5) Record keeping of hours of operation, including what classified the
operation as emergency and how many hours are spent for non-emergency operation. For emergency engines greater than or equal to 130
HP, record keeping of hours of operation begins January 1, 2011. For emergency engines less than 130 HP, record keeping of hours of oper-
ation begins January 1, 2009; engines are equipped with non-resettable hour meters to facilitate record keeping.
Specific Air Quality Management or Air Pollution Control Districts may have different and additional record keeping/reporting requirements.
Your permit to construct and/or operate the engine may be contingent upon compliance with those requirements. Check with your local Air
Quality Management or Air Pollution Control District for specific requirements.
Emergency stationary internal combustion engines (ICE) may be operated for the purpose of maintenance checks and readiness testing,
provided that the tests are recommended by Federal, State or local government, Generac, or the insurance company associated with the
engine. Maintenance checks and readiness testing of such units is limited to 100 hours per year. There is no time limit on the use of emer-
gency stationary ICE in emergency situations. The purchaser/owner may petition the Administrator for approval of additional hours to be
used for maintenance checks and readiness testing, but a petition is not required if the owner maintains records indicating that Federal,
State, or local standards require maintenance and testing of emergency ICE beyond 100 hours per year. Emergency stationary ICE may
operate up to 50 hours per year in non emergency situations, but those 50 hours are counted towards the 100 hours per year provided for
maintenance and testing.
The 50 hours per year for non-emergency situations cannot be used for peak shaving or to generate income for a facility to supply power to
an electric grid or otherwise supply power as part of a financial arrangement with another entity. For purchaser/owner of emergency engines,
any operation other than emergency operation, maintenance and testing, and operation in non-emergency situations for 50 hours per year,
as permitted in this section is prohibited.
If you operate and maintain your certified emergency stationary SI internal combustion engine and emissions control systems in accordance
to the specifications and guidelines in this Owner’s Manual, EPA will not require engine performance testing. If not, your engine will be con-
sidered non-certified and you must demonstrate compliance according to Subpart JJJJ - Standards of Performance for Stationary Spark Igni-
tion Internal Combustion Engines as listed in the Electronic Code of Federal Regulations Title 40 Part 60.
Emission-Related Installation Instructions
Your certified emergency stationary engine has pre-set emission control systems or components that require no adjustment. Inspection and
replacement of an emissions related component is required to be done so in accordance with the requirements cited in the United States
Environmental Protection Agency Warranty Statement or can be arranged by contacting either your selling dealer or a Generac Authorized
Warranty Service dealer, 1-800-333-1322 for the dealer nearest you. Failing to follow these instructions when installing a certified engine in a
piece of non-road equipment violates federal law 40 CFR 1068.105 (b), subject to fines or penalties as described in the Clean Air Act.
