IMPERIAL COUNTY AIR POLLUTION CONTROL DISTRICT 

RULE 802 - BULK MATERIALS 

(Adopted 11/08/2005) 

A. Purpose 

The purpose of this regulation is to reduce the amount of fine Particulate Matter (PM-10) 

entrained in the ambient air as a result of emissions generated from outdoor handling, 

storage, and transport of Bulk Material by requiring actions to prevent, reduce, or 

mitigate PM-10 emissions. 

B. Applicability 

This rule applies to the outdoor handling, storage, and transport of Bulk Material, 

including, but not limited to, earth, rock, silt, sediment, sand, gravel, soil, fill, Aggregate 

Materials, dirt, mud, debris, and other organic and/or inorganic material consisting of or 

containing Particulate Matter with five percent or greater silt content. 

C. Definitions 

The definitions of terms found in Rule 800 (General Requirements for Control of Fine 

Particulate Matter (PM-10) shall apply to this rule. 

D. Exemptions 

 In addition to the exemptions listed in Rule 800, Section E, the following exemptions are 

established for this rule: 

D.1 Outdoor storage, transport, or handling of Bulk Materials (including, but not 

limited to, organic or inorganic fertilizer, grains, seed, soil amendments, and feed)

which would be damaged by wetting with water or by the application of Chemical 

Stabilization/Suppression, provided owners/operators demonstrate to the 

satisfaction of the APCO that none of the control measures required by this rule 

can be implemented to limit VDE to 20% opacity or provide a Stabilized Surface, 

as defined in Rule 800. 

D.2 Outdoor storage or handling of any Bulk Material at a single site where no 

material is actively being added or removed at the end of the workday or 

overnight and where the total material stored is less than 100 cubic yards. 

D.3 Transport of a Bulk Material in an outdoor area for a distance of twelve feet or 

less with the use of a chute or conveyor device. 

D.4 Transport/hauling of Bulk Materials when conducted within the boundaries of a 

premises, are exempt from the requirements specified in Sections F.3.a and F.3.d.
 

E. Requirements 

 E.1 Bulk Material handling: no Person shall cause, suffer, allow or engage in any 

Bulk Material handling operation including, but not limited to stacking, loading, 

unloading, conveying and reclaiming of Bulk Material, for industrial or 

commercial purposes without complying with one or more of the requirements of 

Section F.1 so as to limit VDE to 20% opacity. 

 E.2 Bulk Material storage: no Person shall cause, suffer, allow or engage in any Bulk 

Material storage, for industrial or commercial purposes without complying with 

one or more of the requirements of Section F.2 so as to limit VDE to 20% opacity. 

 E.3 Material transport: no Person shall cause, suffer, allow or otherwise engage in the 

transportation of Bulk Materials for industrial or commercial purposes, without 

complying with all of the requirements of Section F.3 so as to limit VDE to 20% 

opacity. 

E.4 Haul Trucks: no Person shall cause, suffer, allow or otherwise engage in the use 

or operation of any Haul Truck, for industrial or commercial purposes, of 

transporting or storing Bulk Material without complying with all of the 

requirements of Section F.3 so as to limit VDE to 20% opacity. 

F. Best Available Control Measures for Fugitive Dust (PM-10) 

 F.1 BULK MATERIAL HANDLING/TRANSFER: 

 F.1.a Spray with water prior to handling and/or at points of transfer; or. 

 F.1.b Apply and maintain Chemical Stabilization, or 

 F.1.c Protect from wind erosion by sheltering or enclosing the operation and 

transfer line. 

 F.2 BULK MATERIAL STORAGE 

 F.2.a When storing Bulk Materials, comply with the conditions for a Stabilized 

Surface; or 

 F.2.b Cover Bulk Materials stored outdoors with tarps, plastic, or other suitable 

material and anchor in such a manner that prevents the cover from being 

removed by wind action, or 

 F.2.c Construct and maintain barriers with less than 50% porosity. If utilizing 
fences or wind barriers, apply water or chemical/organic 

stabilizers/suppressants, or 

 F.2.d Utilize a 3-side structure with a height at least equal to the height of the 

storage pile and with less than 50% porosity. 

 F.3. MATERIAL TRANSPORT/HAULING: 

 F.3.a Completely cover or enclose all Haul Truck loads of Bulk Material. 

 

F.3.b Haul Trucks transporting loads of Aggregate Materials shall not be 

required to cover their loads if the load, where it contacts the side, front, 

and back of the cargo container area remains six inches from the upper 

area of the container area, and if the load does not extend, at its peak, 

above any part of the upper edge of the cargo container area (As defined in 

Section 23114 of the California Vehicle Code for both public and private 

roads). 

 F.3.c The cargo compartment(s) of all Haul Trucks are to be constructed and 

maintained so that no spillage and loss of Bulk Material can occur from 

holes or other openings in the cargo compartment's floor, side, and/or 

tailgate. Seals on any openings used to empty the load including, but not 

limited to, bottom-dump release gates and tailgates to be properly 

maintained to prevent the loss of Bulk Material from those areas. 

 

 F.3.d The cargo compartment of all Haul Trucks is to be cleaned and/or washed 

at delivery site after removal of Bulk Material. 

G. Record of Control Implementation 

Any Person subject to the requirements of this rule shall compile and retain records that 

provide evidence of control measure application (i.e., receipts and/or purchase records). 

Such Person shall describe, in the records, the type of treatment or control measure, 

extent of coverage, and date applied. For control measures which require multiple daily 

applications, recording the frequency of application will fulfill the recordkeeping 

requirements of this rule (i.e., water being applied three times a day and the date) Records 

shall be maintained and be readily accessible for two years after the date of each entry 

and shall be provided to the APCD upon request.

 

H. Violations 

Failure to comply with any provisions of this rule shall constitute a violation of 

Regulation VIII.
