RICE NESHAP is an acronym for Reciprocating Internal Combustion Engines National Emissions Standards for Hazardous Air Pollutants.


The U.S. Environmental Protection Agency (EPA) adopted national emission standards for hazardous air pollutants (NESHAP) in 2010.  The regulations apply to stationary compression ignition (CI) and spark ignition (SI) reciprocating internal combustion engines (<500hp) at area and major sources of hazardous air pollutants (HAPs).


As part of the analysis process alert limits are applied aligned with the EPA guidelines.  Ensure your User Profile’s email preferences are properly defined to receive alert notifications.

Instructions

Registering a RICE NESHAP engine asset:

When registering your engine to apply the RICE NESHAP alert limits, please ensure to complete the designated fields noted below.

Spark Ignited Engines (Natural Gas or Landfill Gas):

  1.  From Assets page, “Create” an Asset
  2. Select Asset Class – “Engine - Natural Gas” or “Engine – Landfill Gas”
  3. Complete the asset registrations attribute fields
  4. For “Cycles” asset attribute, select either “2 CYCLE - RICE NESHAP-USA ONLY” or “4 CYCLE - RICE NESHAP-USA ONLY”

5. “Save” your asset registration


+++ SAMPLING - Submit sample using an Enhanced (blue capped) Mobil Serv sample bottle  +++

              LIMITS - Sample result alert limits for RICE NESHAP spark ignition engines:

 Combustion Ignited Engines (Diesel or Gasoline):

  1.  From Assets page, “Create” an Asset
  2. Select Asset Class – “Engine”
  3. Complete the asset registrations attribute fields
  4. For “Fuel Type” asset attribute, select either “DIESEL - RICE NESHAP-USA ONLY” or “GASOLINE -RICE NESHAP-USA ONLY”

5.“Save” your asset registration


+++  SAMPLING - Submit sample using an Enhanced (blue capped) Mobil Serv sample bottle  +++

              LIMITS - Sample result alert limits for RICE NESHAP combustion ignition engines:

Corrective Action

According to RICE NESHAP standards, if any of the above limits are exceeded:

  • Oil must be changed in the RICE within 2 business days of receiving the results of the analysis or before operating the RICE, whichever is later.
  • Owner or operator must keep records of the parameters that are analyzed as part of the program, the results of the analysis, and the oil changes for the engine.
  • Oil analysis program must be part of the maintenance plan for the engine.
