Rule 2, Definitions: Rule 2 defines terms that are used in multiple rules. The following definitions were removed

from Rule 2 because they are no longer used in any of the District's rules: "Air Pollution Abatement Operation"

and "Photochemically Reactive Solvent."

The term "Acceptable Incinerator" is used only in Rule 23. However, the provisions of Rule 57, Combustion

Contaminants – Specific, better define what an acceptable incinerator would be. An incinerator meeting the

definition in Rule 2 might not be able to meet Rule 57. Therefore, the term "Acceptable Incinerator" was deleted

from Rule 2.

The term "Existing Equipment" was deleted from Rule 2 and redefined in Rule 5 where it is used.

The term "Loading Facility" was deleted from Rule 2. The term is used in Rule 71.3. Definitions for Rule 71.3 are

contained in Rule 71, which already contains a definition of "Loading Facility."

The terms "Major Source" and "Modified Emissions Unit" were deleted from Rule 2. The terms are adequately

defined in all of the rules in which they are used.

The term "Noxious Mist" was used in Rule 50. Rule 50 was amended in a manner that no longer uses the term,

so it was deleted from Rule 2.

The term "Non-Mobile Equipment" was used in Rule 60. Rule 60 was repealed and the term "Non-Mobile

Equipment" was deleted from Rule 2. .

The terms "Process Weight" and "Solid Particulate Matter" are used only in Rule 53. Rule 53 was revised to

include definitions of these terms. Therefore, these terms were deleted from Rule 2. The term "Batch Operation"

was used in the old definition of "Process Weight." Because the new definition of "Process Weight" does not use

the term "Batch Operation", it was deleted from Rule 2.

The term "Particulate Matter" is used in multiple rules. The definition of "Particulate Matter" in Rule 2 was revised

to be consistent with the definitions used in Rules 52 and 53. The revised definition of "Particulate Matter" no

longer includes the word "Dust." Therefore the definition of "Dust" was deleted from Rule 2.

A temperature of 70 degrees Fahrenheit is specified in the term "Standard Conditions." The standard was

amended to 68 degrees Fahrenheit for consistency with U.S. Environmental Protection Agency (EPA) and

California Air Resources Board (ARB) regulations.

Rule 5, Effective Date: A definition for the term "Existing Equipment" was added.

Rule 10, Permits Required: Part 70 (Title V) permit renewal requirements were clarified.

Rule 30, Permit Renewal: Part 70 (Title V) permit renewal requirements were clarified.

Rule 42. Permit Fees: Section H was revised to increase permit fees and define acronyms. Outdated language

was deleted from section B.2.a. Section K, California Clean Air Act Fee, was deleted. The California Air

Resources Board (ARB) is in the final stages of amending the California Clean Air Act Nonvehicular Source Fee

regulation. One of ARB's amendments will allow the state to collect this fee directly, rather than relying on the

District.

Rule 45.1, ECO Plan Fees was repealed. It was obsolete

Rule 50, Opacity was revised to specify EPA Method 9, Visual Determination of the Opacity of Emissions From

Stationary Sources, for determining compliance. By specifying Method 9, Notes 1-3 in Section A could be

deleted. Additionally, state law prohibits air districts from applying the rule to certain sources, including pile

drivers, open fires, dust from agricultural operations, abrasive blasting operations, and others. Some of these

exemptions are currently listed in Rule 55. Staff added exemptions to Rule 50 to reference these state limitations

on local authority. Revised subsection C.3 does not exempt combustion equipment used in agricultural

operations because the term "dust" does not apply to combustion contaminants.

Rule 51, Nuisance: Agricultural odors must be exempted from Rule 51 pursuant to state law. This exemption

was in Rule 55. Staff is moved the exemption for agriculture odors to Rule 51.

Rule 52, Particulate Matter – Concentration: Rule 52 sets limits on the concentration of particulate matter that

may be emitted from any source. The only exemptions listed in the rule were for gas turbines and steam

generators that burn liquid or gaseous fuels. The rule was revised to specify that "boilers, steam generators,

water heaters, process heaters, space heaters, gas turbines, internal combustion engines, and flares that

combust liquid or gaseous fuels or waste gases and emit only combustion products" are all exempt from Rule 52.

Regulation of particulate matter from these devices is not necessary because EPA emission factors (AP-42) for

boilers, process heaters, natural gas internal combustion engines, and diesel engines fueled with either natural

gas or fuel oil are lower than the emission limits imposed by Rule 52. The rule was also revised to exempt

abrasive blasting and open fires already regulated by Rules 74.1 and 56, respectively. These exemptions reflect

the District's historical application of Rule 52. Appropriate test methods and definitions were also added.

Rule 53, Particulate Matter - Process Weight: Rule 53 sets emission limits on the amount of solid particulate

matter that may be released from any source based on throughput (i.e., process weight). The definition of

"Process Weight" implies that combustion contaminants from gaseous fuels were not intended to be covered by

Rule 53. Test methods, exemptions, and definitions are added in a similar manner as Rule 52. Additionally, a

typographical error in column 2 of the table on page one is corrected.

Rule 55, Exemptions from Emission Standards was repealed. The exemptions specified in Rule 55 from Rules

50 and 51 were moved to those rules. The exemption in Section C.3 for "Short duration, infrequently operated

sources engaged in experimental or research operations not exceeding an aggregate of two hours per month"

has never been claimed and was deleted.

Rule 60, New Non-Mobile Equipment - Sulfur Dioxide, Nitrogen Oxides, and Particulate Matter is obsolete and

was repealed. Rule 60 prohibited construction of any device that would emit more than 200 pounds per hour

(pph) of sulfur oxides, 140 pph of oxides of nitrogen, or 10 pph of particulate matter from the burning of a fuel.

These emission rates are equal to 800 tons per year (tpy) sulfur oxides, 560 tpy oxides of nitrogen, and 40 tpy of

particulate matter (assuming 8000 hours of operation per year). These would be very large sources. The rule

has not been triggered in staff's memory. These emission rates exceed the current balances for these pollutants

in the District emission reduction credit bank. Obtaining offsets of this magnitude would be very difficult, if not

impossible. Rule 26, New Source Review, has effectively replaced Rule 60. Rule 26 requires all new sources to

control air pollutants using Best Available Control Technology (BACT) and requires all new emissions to be offset.

Rule 62.3, Hexavalent Chromium – Cooling Towers; Rule 62.4, Asbestos – Serpentine Rock for Surfacing; and

Rule 62.5, Dioxins – Medical Waste Incinerators are proposed to be repealed. The Ventura County APCD Board

adopted the rules in 1990 and 1991. Rule 62.3 implements the California Airborne Toxic Control Measure

(ATCM) for the control of hexavalent chromium from cooling towers. Rule 62.4 implements a previous version of

the ATCM for the control of asbestos emissions from unpaved roads surfaced with serpentine rock. Rule 62.4 is

no longer current because CARB modified the ATCM on July 20, 2000. Rule 62.5 implements the ATCM for the

control of dioxin emissions from medical waste incinerators. California Health and Safety Code (H&SC) Section

39666(d), as it existed in 1990 and 1991, required air districts to adopt rules to implement state ATCMs. Since

that time, H&SC Section 39666(d) has been revised to allow air districts to implement ATCMs directly, without

adopting local implementation rules. Therefore, it is not necessary to maintain current versions of these locally

adopted rules in the Ventura County APCD rulebook.

Rule 68, Carbon Monoxide: Rule 68 limits CO emissions from any source to 2,000 parts per million (ppm). The

current rule exempts "emissions from internal combustion engines, jet engine or rocket engine test stands, or

rocket propellant or rocket fuel testing devices." The rule was amended to specify that boilers, steam generators,

water heaters, process heaters, space heaters, internal combustion engines, gas turbines, jet engine test stands,

rocket engine test stands, flares, and open outdoor fires are exempt from Rule 68. Boilers, steam generators,

water heaters, and process heaters larger than 400,000 Btu/hr are subject to more stringent CO limits pursuant to

Rules 74.11.1, 74.15, 74.15.1 and 59. Because Rule 68 was not intended to apply to smaller units such as

residential water heaters and space heaters, they were also exempted. EPA emission factors show that CO

emissions from gas turbines and flares are less than 2000 ppm. Non-exempt sources subject to Rule 68 include

drum-mix driers and aggregate driers at asphalt batch plants, incinerators, kilns, and smelters. Appropriate test

methods and definitions were also added.

Rule 100, Analytical Methods is obsolete and was repealed. Appropriate test methods are now specified in each

applicable rule that sets an emission limit. The repeal of Rule 100 included repeal and elimination of Appendixes

A, B, C, D, and F, which are referenced in Rule 100.

Rule 102, Source Tests: Minor corrections were adopted regarding the schedule for source testing and reporting.

The rule was also revised to state that appropriate test methods are specified in the applicable rules that set the

emission limits.
