Applicability. This section applies to any nonroad engines as defined in WAC
173-400-030, except for:
(a) Any nonroad engine that is:
(i) In or on a piece of equipment that is self-propelled or serves a dual purpose by both propelling itself and performing another function; or
(ii) In or on a piece of equipment that is intended to be propelled while performing its function.
(b) Nonroad engines with a cumulative maximum rated brake horsepower of 500 BHP or less.
(c) Engines being stored in work centers, garages, or engine pool sites prior to being dispatched to the field for use and that do not provide back-up power at the work center, garage, or engine pool. Such engines may be operated at these facilities only for the purpose of engine maintenance, testing, and repair.
(d) A back-up nonroad engine demonstrated to have the same or lower emissions than the primary power nonroad engine.
(2) Nonroad engines are not subject to:
(a) New source review.
(b) Control technology determinations.
(c) Emission limits set by the SIP.
(3) Fuel standards. All nonroad engines must use ultra low sulfur diesel or ultra low sulfur biodiesel (a sulfur content of 15 ppm or 0.0015% sulfur by weight or less), gasoline, natural gas, propane, liquefied petroleum gas (LPG), hydrogen, ethanol, methanol, or liquefied/compressed natural gas (LNG/CNG). A facility that receives deliveries of only ultra low sulfur diesel or ultra low sulfur biodiesel is deemed to be compliant with this fuel standard.
(4) ˃ 500 and ≤ 2000 BHP. This section applies to a project that requires the installation and operation of nonroad engines with a cumulative maximum rated brake horsepower greater than 500 BHP and less than or equal to 2000 BHP.
(a) Notification of intent to operate is required before operations begin.
The owner or operator must notify the permitting authority of their intent to operate prior to beginning operation. The notice must contain the following information:
(i) Name and address of owner or operator;
(ii) Site address or location;
(iii) Date of equipment arrival at the site;
(iv) Cumulative engine maximum rated BHP.
(b) Recordkeeping. For each site, the owner or operator must record the following information for each nonroad engine:
(i) Site address or location;
(ii) Date of equipment arrival at the site;
(iii) Date of equipment departure from the site;
(iv) Engine function or purpose;
(v) Identification of each component as follows:
(A) Equipment manufacturer, model number and its unique serial number;
(B) Engine model year;
(vi) Type of fuel used with fuel specifications (sulfur content, cetane number, etc.).
(c) Record retention requirements. The owner or operator must keep the records of the current engine and equipment activity in hard copy or electronic form. These records can be maintained on-site or off-site for at least five years and must be readily available to the permitting authority on request.
(5) ˃ 2000 BHP. This section applies to a project that requires the installation and operation of nonroad engines with a cumulative maximum rated brake horsepower greater than 2000 BHP.
(a) Notification of intent to operate.
(i) Prior to operation, the owner or operator must notify the permitting authority of the intent to operate and supply sufficient information to enable the permitting authority to determine that the operation will comply with national ambient air quality standards as regulated by WAC
173-400-113 (3) and (4).
(ii) The notification must contain, at a minimum, the information in subsection (4)(a) of this section.
(b) Approval is required before operations begin. The owner or operator must obtain written nonroad engine approval to operate, from the permitting authority, prior to operation.
(c) Recordkeeping. The owner or operator must meet all of the requirements of subsection (4)(b) and (c) of this section.
(6) Integrated review. Applicants seeking approval to construct or modify a stationary source that requires review under WAC
173-400-110 or
173-400-560 and to operate one or more nonroad engines in conjunction with the new or modified stationary source may elect to integrate the reviews. The notification process for integrated review must comply with the new source review public involvement procedures for the stationary source as applicable (i.e., WAC
173-400-171 or
173-400-740).
(7) Enforcement. All persons who receive a nonroad engine approval to operate must comply with all conditions contained in the approval.
(8) Permitting authority review period. Within fifteen days after receiving a complete notice of intent to operate, the permitting authority must either issue the approval to operate or notify the applicant that operation must not start until the permitting authority has set specific operating conditions. The permitting authority must promptly provide copies of the final decision to the applicant.
(9) Conditions to assure compliance with NAAQS. Subject to the limitations of subsection (2) of this section, the permitting authority may set specific conditions for operation as necessary to ensure that the nonroad engines do not cause or contribute to a violation of National Ambient Air Quality Standards.
(10) Appeals. Final decisions and orders of ecology or a permitting authority may be appealed to the pollution control hearings board as provided in chapters
43.21B RCW and
371-08 WAC.
(11) Change of conditions. The owner or operator may request, at any time, a change in conditions of an approval to operate. The permitting authority may approve the request provided that the permitting authority finds that the operation will comply with WAC 173-400-113 (3) and (4).
