RULE 80 6 CONS ERVATION MANAGEMENT PRACTICES (Adopted 11/08/2005 ; Revised __/__/____ )

A. Purpose

The purpose of this regulation is to reduce the amount of coarse fine Particulate Matter (PM

- 10) entrained in the ambient air as a result of emissions generated from Agricultural Operation Sites by requiring Conservation Management Practices to prevent, reduce, or mitigate PM

- 10 emissions.

B. Applicability

This rule applies to Agricultural Operation Sites located within the Imperial County. Effective on and after January 1, 2013

, January 1, 2006 , an owner/operator shall implement the applicable CMPs selected for each Agricultural Operation Site. The provisions of this rule adopted on November 8, 2005 shall remain in effect until January 1, 2013 at which time the amendments adopted on October 16, 2012 shall take effect.

C. Definitions

In addition to the definitions of terms in Rule 800 (General Requirements for Control of Fine Particulate Matter (PM

- 10), the following definitions shall govern

th e implementation of t his rule:

C.1 AGRICULTURAL OPERATIONS: The growing and harvesting of crops for the primary purpose of earning a living.

C.2 AGRICULTURAL OPERATION SITE: One or more agricultural parcels that meet the following:

C.2.a Are under the same or common ownership or operation, or which are owned or operated by entities which are under common control;

and

C.2.b Are located on one or more contiguous or adjacent properties wholly within Imperial County.

C.3 AGRICULTURAL PARCEL: A portion of real property used by an owner

or ope rator for carrying out a specific agricultural operation. Roads, vehicle/equipment traffic areas, and facilities, on or adjacent to the cropland are part of the agricultural parcel.

C.4 ALTERNATIVE TILLING: Rotate tillage leaving residue on soil. Till ing

al ternative rows for weed management , reducing and wind blown dust

allows for approximately 50% of reduction in field activity related to tilling

,

806

- 1Imperial County Air Pollution Control District R ule 806

in addition to stabilizing soil surface and reducing soil compaction.

C.5 APPLICATION EFFICIENCIES: Use more efficient application equipment so as to reduce a minimum of one ground operation. Examples include: compact or low volume spray equipment; aerial applications; micro

- heads or infrared spot sprayers; electrostatic spray ers. Reduces soil compaction, passes and chemical usage.

C. 6 5 BALING/LARGE BALES: Reduce a minimum of one pass through the field per acre by using large balers to harvest crops. Using balers to harvest crop. It reduces PM emissions from crops traditional ly harvested by chopping, truck, passes and residue burning.

C. 7 6 BED/ROW SIZE OR SPACING: Reduce a minimum of one tillage operation by Increas ing e or decreas ing e the size of the planting bed area (can be done for field and permanent crops) or adjusting spacing

. Spacing adjustments reduce the number of passes and soil disturbance by increasing plant density/canopy through reduction of row width to contain PM within the canopy.

C.8 BULK MATERIALS CONTROL: Minimize visible dust emissions from bulk materials by using dust suppressant or water to form a stabilized surface, or using a tarp to fully cover the pile or truckbed, or using a wind barrier or

3

- sided structure to reduce entrai nment of fugitive dust.

C. 9 7 CHEMIGATION/FERTIGATION: Reduce a minimum of one ground operation by applying Application of chemicals through an irrigation
system. This Each application reduces the need to travel in the field for application purposes, thus reducing operations the number of passes and soil disturbance while increasing the efficiency of the application.

C. 10 8 CHIPS/MULCHES, ORGANIC MATERIALS, POLYMERS, ROAD OIL & SAND: Application of any nontoxic chemical or organic dust suppressant that meets all specification required by any federal, state, or local water agency and is not prohibited for use by any applicable regulations. Chips/Mulches and organic materials shou ld meet the specifications in the mulches definition below. Polymers, road oil and sand should create a stabilized surface during high traffic times such as harvest.

C 11

. 9 COMBINED OPERATION: To c C ombine equipment to perform several operations during one pass , thereby reducing a minimum of one tillage operation

. The reduction in the number of passes necessary to cultivate

the land will result in fewer disturbances to the soil. Examples include:

use of o ne

- pass till equipment in ground preparation or crop tillage; and cultivation and fertilization of a field crop in a single pass. Other benefits are reduction of soil compaction and time to prepare fields, both of which

806

- 2Imperial County Air Pollution Control District R ule 806

can be precursors to additional til lage requirements. If a combined operation is accomplished through equipment change/technological improvement, that action is considered one CMP, and either Equipment Changes/Technological Improvements CMP or Combined Operations CMP may be selected in a CM P Plan, but not both.

C.1 2 0 CONSERVATION IRRIGATION: Reduce a minimum of one tillage operation related to weeding by To conserv ing e the amount quantity of

water use d by using either , e.g.: drip, sprinkler, or buried/underground line irrigation . Conservin g water reduces weed population, which in turn reduces the need for tillage and as well as reduces soil compaction.

C.1 5 3 CONSERVA TION TILLAGE (e.g.: no tillage, minimum tillage): A tillage system that reduces a minimum of three tillage operations. This system reduces soil and water loss by reducing the number of passes and by leaving crop residue on the field after harvest as well a s managing the residue so that it remains intact during the planting season

. Types of tillage that reduce loss of soil and water in comparison to Conventional Tillage. It reduces the number of passes and amount of soil disturbance. It improves soil becau se it retains plant residue and increases organic

matter.

C.1 6 4 COVER CROPS: Establish cover crops that maintain a minimum of 60 percent ground cover, as determined by the L l ine

- intersection Transect

Test M m ethod . Native or volunteer vegetation that meets the minimum ground cover requirement is acceptable. Use seeding or natural vegetation/regrowth of plants to cover soil surface. It reduces soil

disturbance due to wind erosion and entrainment.

C.17 CROP RESIDU E MANAGEMENT: Maintain crop residue from previous crops until tilling for the next crop. Crop residues must maintain a minimum of 60 percent ground cover as determined by L l ine

- intersection

Transect Test M m ethod. Implements such as undercuters or sweeps ca n maintain crop residues without burying or destroying residues.

It reduces the number of passes during an operation, thereby reducing soil

disturbance. Reduce a minimum of one tillage operation by modifying equipment or making technological improvements. Examples include flame cultivation or equipmen t that combines discing, chiseling and ring rolling.

or til lage operation by using Use biological control methods or non

chemical control methods. It reduces chemical use, thereby reducing

passes. Examples include: organic certification, biological controls, mulches and humus.

consistent with NRCS Code 609

– Surface Roughening.

C.5 0 TILLAGE OPERATION: An agricultural operation that mechanically manipulates the soil for the enhancement of crop production. Examples include discing, weeding, or bedding. A pass through the field may be a subset of a tillage operation.
