United States Environmental Protection Agency Compliance Requirements
Purchaser's/Owner's Recordkeeping Responsibilities
The United States Environmental Protection Agency (EPA) and Generac Power Systems, Inc. (Generac), are pleased to explain
your recordkeeping 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 ap-
plicable emission related guidelines as specified in this Owner's Manual you are required to meet the following notification and
recordkeeping requirements to demonstrate compliance. 1.) Maintain documentation that the engine is certified to meet emission
standards. 2.) Recordkeeping of maintenance conducted. 3.) Recordkeeping 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.) Recordkeeping 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 , recordkeep-
ing of hours of operation begins January 1, 2011. For emergency engines less than 130 HP , recordkeeping of hours of operation
begins January 1, 2009; Engines are equipped with non-resettable hour meters to facilitate recordkeeping.
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 emergency 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 situa-
tions 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 considered non-certified and you must demonstrate compliance according to Subpart JJJJ – Standards of Per-
formance for Stationary Spark Ignition 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. In-
spection 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 your selling dealer
or a Generac Authorized Warranty Service dealer, 888-GENERAC (888-436-3722) or www.generac.com for the dealer nearest you.
Failing to follow these instructions when installing a certified engine in a piece of nonroad equipment violates federal law 40 CFR
1068.105 (b), subject to fines or penalties as described in the Clean Air Act.
