U.S. EPA Legal Requirements
The ZPP NA428 & NA857 Natural Gas and LPG Vapor engines have
been certified by the U.S. Environmental Protection Agency (EPA) as
Stationary Emergency Engines
. It is illegal to operate these engines in
a prime or emergency mobile application or a prime stationary
application.
Per 40 CFR 60.4243(d), you may operate your
Stationary Emergency
Engine
for an unlimited number of hours in emergency situations. You
may also operate your engine for up to 50 hours per year in non-
emergency situations for maintenance purposes.
To ensure emissions compliance, the U.S. EPA requires you to do one of
the following two options:
1. Operate and maintain your engine as specified in this Operators
Manual. In addition, you are required by law to keep detailed
maintenance records.
2. If you operate your engine as a
Stationary Emergency Engine
but do not operate and maintain your engine as specified in this
Operators Manual, your engine will be considered a non-certified
engine.
In this case, you must:
x
Keep a maintenance plan and records of conducted
maintenance.
x
To the extent practicable, maintain and operate the engine in
a manner consistent with good air pollution control practice
for minimizing emissions.
x
Conduct an initial performance test within 1 year of engine
startup to demonstrate compliance (NA857 only). Contact
your regional EPA office for instructions on how to conduct
an initial performance test.
Per section 113 of the U.S. Clean Air Act, failure to abide by these legal
requirements can result in fines up to $29,750 per day.
A maintenance plan and log are provided at the back of this manual for
you to record your engine maintenance. Update the log each time you
service your engine.
