405.2 The APCO shall transfer an additional 5% of the calculated quantity of emission 

reductions to the Priority Reserve Bank.

405.3 The APCO shall retire an equivalent percentage of the calculated quantity of 

emission reductions to account for expected future improvements in the fleet, as 

determined by Section 401.4.

406 VIOLATIONS:

406.1 Failure to comply with any provision of this rule or permit condition established 

pursuant to this rule shall constitute a violation of this rule.

406.2 Failure to provide the quarterly emission reduction incorporated in the permit to 

operate for the control device shall be considered an emission reduction shortfall and 

shall be a separate violation for each day of the quarter. If an emission reduction 

shortfall occurs, the permittee shall take the following corrective actions in order:

406.2.1 The permittee shall average the actual emission reductions reported for the 

previous four quarters to determine if a sufficient quantity of actual emission 

reductions occurred to satisfy the quarterly emission reduction requirement 

on an annual basis. If the annual emission reductions satisfy the quarterly 

emission reduction requirement, the violation will be deemed resolved, if not 

the permittee shall comply with (ii) below.

406.2.2 The permittee shall submit a compliance plan quantifying the amount of the 

emission reduction shortfall and indicating how the emission reduction 

shortfall will be remedied within the next 4 quarters. Such remedies may 

include cancelling any unused ERCs, reducing additional emissions during 

any of the next four quarters, such that on an annual basis the required 

quarterly amount of emission reductions is provided, or purchasing and 

retiring the necessary amount of ERCs. 

406.3 Unnecessary idling or load testing for the sole purpose of providing the quarterly 

emission reduction or make-up of a prior quarter shortfall in emission reductions shall 

be a violation of this rule and the permit to operate.

406.4 If a compliance plan is not submitted or any emission reduction shortfall is not made 

up within four quarters of the shortfall occurrence, and any portion of the ERC 

certificate remains unused, a portion of the ERC certificate equivalent to the shortfall 

shall be revoked by the District. 

406.5 If activity levels at the rail yard fall below those projected pursuant to Section 401.3, 

the permittee may submit an application to revise the quarterly emission reductions 

required, based on the new activity levels. EPA must also provide written 

concurrence as to any new quarterly emission reduction requirement prior to 

issuance of a revised permit to operate.

STATIONARY RAIL YARD CONTROL EMISSION 

REDUCTION CREDITS

Prepared By:

Don Duffy,

Consultant to the Air Pollution Control District
STAFF REPORT ▫ Rule 515 Amendment

INTRODUCTION

The purpose of Rule 515, Stationary Rail Yard Control Emission Reduction Credits, is to provide 

owners of a rail yard a mechanism for quantifying, certifying, and banking emission reductions 

from the installation and use of a control device which reduces emissions from locomotive 

engines in rail yards. Rule 515 has been reviewed by EPA for incorporation into the State 

Implementation Plan (SIP) which resulted in several unofficial issues to be corrected before the 

rule can be approved. The District agreed to withdraw the rule from SIP consideration and 

amend it to resolve the EPA approval concerns.

When the owner or operator of a stationary source of air pollution wishes to install a new source 

or modify an existing source of air pollution, he or she must obtain a permit from the District. 

The District evaluates the proposed new air emissions through a process called “New Source 

Review”. If the increase in criteria pollutants is above a certain threshold, the owner or operator

must “offset” these emissions by providing for reduced emissions from another nearby source. 

This is done through acquiring Emission Reduction Credits (ERC). ERCs are generated for 

facilities that reduce emissions according to District rules. Rule 504, Emission Reduction 

Credits, is the general rule and applies to most situations. Rule 515, Stationary Rail Yard 

Control Emission Reduction Credits, is a specific rule that applies only to the reduction of 

emissions from locomotives in rail yards.

BACKGROUND

Rule 515 was promulgated on October 8, 2008 and sent to the California Air Resources Board 

(ARB) on November 5, 2008 and then submitted to EPA for SIP consideration by ARB on 

December 23, 2008. 

In June 2014 an EPA staff member contacted the District to notify the District that Rule 515 was 

being reviewed for SIP approval and there are several issues that make the rule un-approvable as 

written. The rule was withdrawn from SIP consideration by a letter from the District to ARB on 

July 7, 2014, in order to avoid formal disapproval occurring through a Federal Register Notice. 

EPA and the District agreed to collaborate on finding acceptable rule language to allow the rule 

to be re-submitted for SIP approval. This amendment incorporates the changes agreed to by both 

EPA and the District.

Rule 515 is an outgrowth of the December, 2004, Memorandum of Understanding (MOU) 

between the District and Union Pacific Railroad Company to reduce emissions from the J.R. 

Davis Rail Yard in Roseville. One of the elements of this work was development and feasibility 

testing of control equipment capturing and treating diesel exhaust emissions from stationary 

locomotive engines at the yard. This control equipment was called the Advanced Locomotive 

Emission Control System (ALECS) and often referred to as the “hood”. ALECS demonstrated 

over 90% control of NOx, SOx, and PM-10/PM-2.5. 

This rule was promulgated to provide a means of obtaining emission reduction credits (ERCs) 

for installing and operating such a control system on locomotive exhaust at the rail yard. Because 

ERCs are difficult to create and are required for new large sources of air emissions, any ERCs
STAFF REPORT ▫ Rule 515 Amendment (continued)

created through stationary locomotive emission reductions are marketable to others if not utilized 

by the ERC owner. Therefore the value of the ERCs serves as an incentive to reduce stationary 

locomotive emissions.

AMENDMENTS OF RULE 515

Staff is proposing to make a number of amendments to the rule to gain EPA SIP approval. These 

amendments are described below. A strikeout version of the amended rule is included as Exhibit 1

to this staff report.

Owners or Operators

The rule addresses the applicant for ERCs as the “owners or operators” of the control system. 

EPA is taking the position that the party responsible for insuring that the conditions of the 

operating permit and the ERCs must be the owner of the rail yard since a third party owner 

and operator of the control equipment would have no authority to require the locomotives to 

utilize the control system.

In all places where “owners or operators” is stated, it is changed to “operators”.

Final ERC Issuance

Section 303 of the rule requires that the operating permit for the control equipment contain 

certain conditions before ERCs can be issued for the emission reductions provided by the 

control equipment. One EPA concern is that the control equipment is shut down and does 

not continue to provide the emission reductions to support the ERCs. A condition is added to 

address this situation.

303.3 A statement that the permittee may not retire the permit for the control device 

unless the rail yard is shutdown or the permittee surrenders to the District a 

Certified ERC certificate for the same quantity of quarterly emission reductions 

required by the permit.

The violation section (section 406) of the rule has been enhanced. A condition in section 303 

is added to incorporate in the operating permit the following:

303.4 Statements that incorporate all of the provisions of Section 406-Violations.

Calculation of Emission Reductions

Section 401 specifies the procedures and content of the applicant’s application for ERCs to 

the District. Section 401.4 requires that the applicant provide an analysis of how future 

reductions in emissions from locomotives due to newer, lower-emitting engines in the 

locomotive fleet will reduce the emissions available to be treated by the control equipment. 

A requirement in this section that required discounting of the emission reductions in the 

future due to improvements in the fleet is moved to Section 405.3 and reworded slightly. 
STAFF REPORT ▫ Rule 515 Amendment (continued)

405.3 The APCO shall retire an equivalent percentage of the calculated quantity of 

emission reductions to account for expected future improvements in the fleet, as 

determined by Section 401.4.

Violations

Section 406, Violations, mainly deals with the situation where the owner of the rail yard does 

not provide the quarterly emission reductions from the control system to support the ERCs 

issued pursuant to this rule. Section 406.2 has been reworded and expanded to read:

406.2 Failure to provide the quarterly emission reduction incorporated in the permit to 

operate for the control device shall be considered an emission reduction shortfall 

and shall be a separate violation for each day of the quarter. If an emission 

reduction shortfall occurs, the permittee shall take the following corrective 

actions in order:

406.2.1 The permittee shall average the actual emission reductions reported for 

the previous four quarters to determine if a sufficient quantity of actual 

emission reductions occurred to satisfy the quarterly emission reduction 

requirement on an annual basis. If the annual emission reductions 

satisfy the quarterly emission reduction requirement, the violation will 

be deemed resolved. If not, the permittee shall comply with 406.2.2 

below.

406.2.2 The permittee shall submit a compliance plan quantifying the amount of

the emission reduction shortfall and indicating how the emission 

reduction shortfall will be remedied within the next 4 quarters. Such 

remedies may include cancelling any unused ERCs, reducing additional 

emissions during any of the next four quarters, such that on an annual 

basis the required quarterly amount of emission reductions is provided, 

or purchasing and retiring the necessary amount of ERCs.

Renumbered Section 406.4 deals with the situation of an emission reduction shortfall and the 

permittee does not submit a compliance plan to specify how the shortfall will be remedied:

406.4 If a compliance plan is not submitted or any emission reduction shortfall is not 

made up within four quarters of the shortfall occurrence, and any portion of the 

ERC certificate remains unused, a portion of the ERC certificate equivalent to the 

shortfall shall be revoked by the District.

Section 406.5 is added to specify the procedure for dealing with the situation where the rail 

yard activity falls below the level that allows support of the ERCs.

406.5 If activity levels at the rail yard fall below those projected pursuant to Section 

401.3, the permittee may submit an application to revise the quarterly emission 

reductions required, based on the new activity levels. EPA must also provide

written concurrence as to any new quarterly emission reduction requirement 

prior to issuance of a revised permit to operate.

Recordkeeping and Reporting

EPA has advised the District that any District rules referenced in a SIP approved rule must 

also be SIP approved. Section 503.4 requires the permittee to report breakdowns of the 

control device per District Rule 404, Upset Conditions, Breakdown or Scheduled 

Maintenance. Since Rule 404 is not SIP approved, this reference is not acceptable. EPA 

suggested deleting this section because Rule 404 would still apply to the permittee since it is 

a District rule. Section 503.4 is deleted.

FISCAL IMPACT

The amendment of Rule 515 will have insignificant fiscal impact on any persons using the rule 

compared with business under the current rule.

ANALYSIS AND FINDINGS

The following Analysis and the subsequent Findings are intended to address the requirements set 

forth in the Health and Safety Code relating to adoption of a new or amended District Rule, as well 

as other State statutes referenced herein.

Cost-Effectiveness of a Control Measure

California Health & Safety Code (H&S) Section 40703 requires a District to consider and make 

public “the cost-effectiveness of a control measure”. The amendment of Rule 515 should have 

insignificant financial impact on permit holders or the public as compared with business under 

the current rule, therefore there is no cost-effectiveness of this amendment.

Socioeconomic Impact

H&S Section 40728, in relevant part, requires the Board to consider the socioeconomic impact 

of any new rule if air quality or emission limits are significantly affected. However, Districts 

with a population of less than 500,000 persons are exempted from the socioeconomic analysis. 

In 2013, the population of Placer County was approximately 357,000 persons.

California Environmental Quality Act (CEQA)

Proposed amended Rule 515 is not an activity that may cause a direct or reasonably foreseeable 

indirect physical effect in the environment therefore not considered a “project”, as defined by 

Section 21065 of the California Public Resource Code and Section 15378(b)(4)&(5) of the 

CEQA guidelines. A CEQA analysis is therefore not necessary.
STAFF REPORT ▫ Rule 515 Amendment (continued)

5

Findings

A. Necessity – The amendment of Rule 515 is necessary in order to obtain federal and 

state recognition of the District’s Emission Reduction Credit rule in the SIP. SIP 

approval of this rule will allow ERCs issued to the rule to be used as offsets for major 

sources and major modifications.

B. Authority – California Health and Safety Code, Sections 40000, 40001, 40701, 40702, 

and 40716 are provisions of law that provide the District with the authority to adopt this 

amended Rule.

C. Clarity – There is no indication, at this time, that the proposed Rule is written in such a 

manner that persons affected by the Rule cannot easily understand them.

D. Consistency – The regulation is in harmony with, and not in conflict with or 

contradictory to, existing statutes, court decisions, or state or federal regulations.

E. Non-duplication – The regulation does not impose the same requirements as an 

existing state or federal regulation.

F. Reference – All statutes, court decisions, and other provisions of law used by PCAPCD 

in interpreting this regulation is incorporated into this analysis and this finding by 

reference.

Rules and Regulations 515-8 Placer County APCD

405 EMISSION REDUCTION CREDIT ADJUSTMENTS OF CALCULATED CREDITS: Before 

the APCO may issue an ERC certificate, the actual emission reductions calculated for each 

calendar quarter pursuant to Section 404 shall be reduced by the following amounts:

405.1 The APCO shall retire 10% of the calculated quantity of NOx emission reductions for 

air quality benefit.

405.2 The APCO shall transfer an additional 5% of the calculated quantity of emission 

reductions to the Priority Reserve Bank.

405.3 The APCO shall retire an equivalent percentage of the calculated quantity of 

emission reductions to account for expected future improvements in the fleet, as 

determined by Section 401.4.

406 VIOLATIONS:

406.1 Failure to comply with any provision of this rule or permit condition established 

pursuant to this rule shall constitute a violation of this rule.

406.2 Failure to provide the quarterly emission reduction incorporated in the permit to 

operate for the control device shall be considered an emission reduction shortfall and 

shall be a separate violation for each day of the quarter. If an emission reduction 

shortfall occurs, the permittee shall take the following corrective actions in order:

406.2.1 The permittee shall average the actual emission reductions reported for the 

previous four quarters to determine if a sufficient quantity of actual emission 

reductions occurred to satisfy the quarterly emission reduction requirement 

on an annual basis. If the annual emission reductions satisfy the quarterly 

emission reduction requirement, the violation will be deemed resolved, if not 

the permittee shall comply with (ii) below.

406.2.1406.2.2 The permittee shall submit a compliance plan quantifying the amount of the 

emission reduction shortfall and indicating how the emission reduction 

shortfall will be remedied within the next 4 quarters. Such remedies may 

include cancelling any unused ERCs, reducing additional emissions during 

any of the next four quarters, such that on an annual basis the required 

quarterly amount of emission reductions is provided, or purchasing and 

retiring the necessary amount of ERCs. Any such shortfall shall be made 

up within four quarters of the shortfall occurrence. The shortfall may be 

made up through...

406.23 Unnecessary idling or load testing for the sole purpose of providing the quarterly 

emission reduction or make-up of a prior quarter shortfall in emission reductions shall 

be a violation of this rule and the permit to operate.

406.34 If the owner is unwilling or unable to produce the emissions reduction required in the 

control device permit to operate and a compliance plan is not submitted or any such 

emission reduction shortfall is not made up within four quarters of the shortfall 

occurrence, and any portion of the ERC certificate remains unused, a portion of the 

ERC certificate equivalent to the shortfall shall be revoked by the District. 

406.5 If activity levels at the rail yard fall below those projected pursuant to Section 401.3, 

the permittee may submit an application to revise the quarterly emission reductions 

required, based on the new activity levels. EPA must also provide written 

concurrence as to any new quarterly emission reduction requirement prior to 

issuance of a revised permit to operate.

Placer County APCD 515-9 Rules and Regulations

501.1 For each control device installed to generate ERCs, the applicant shall install, and 

thereafter operate, maintain, certify, and quality-assure a continuous emission 

monitoring system (CEMS) which measures the inlet and outlet stack gas 

concentrations for each pollutant for which an ERC is to be issued and the oxygen 

concentrations in ppmv. The measured concentrations shall be corrected to 15 

percent oxygen on a dry basis.

501.2 The CEMS shall meet the applicable requirements of 40 CFR 60 Appendix B, 

Performance Specifications 2 and 3, and 40 CFR Part 60 Appendix F, Procedure 1. 

The CEMS shall complete a minimum of one cycle of operations (sampling, analyzing 

and data recording) for each successive 15-minute period. CEMS for PM shall not 

be required to include condensables.

501.3 The CEMS shall be programmed to calculate and record the actual emission 

reductions achieved by the control device, measured in pounds, on a daily basis, and 

summed quarterly.
