RULE 802 - BULK MATERIALS (Adopted 11/08/2005)

A. Purpose

The purpose of this regulation is to reduce th e amount of fine Partic ulate 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, st orage, 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 handli ng 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 ow ners/operators demonstrate to the

satisfaction of the APCO that none of the control measur es 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 Bu lk 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 Materi al in an outdoor area for a distance of twelve feet or

less with the use of a c hute 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 sha ll cause, suffer, allow or engage in any Bulk Material storage, for indus trial or commercial purposes without complying with one or more of the requirements of Secti on F.2 so as to limit VDE to 20% opacity.

E.3 Material transport: no Person shall caus e, suffer, allow or otherwise engage in the transportation of Bulk Mate rials for industrial or co mmercial 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 hand ling and/or at points of transfer; or.

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

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

transfer line

.

F.2 BULK MATERIAL STORAGE

F.2.a When storing Bulk Materials, co mply 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 utilizingfences or wind barriers, apply water or chemical/organic stabilizers/suppressants, or

F.2.d Utilize a 3-side structure with a heig ht at least equal to the height of the storage pile and with le ss than 50% porosity.

F.3. MATERIAL TRAN SPORT/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 lo ad, 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 th e 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 Vehicl e 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 gate s 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 cl eaned and/or washed at delivery site after re moval of Bulk Material.

G. Record of Control Implementation

Any Person subject to the require ments of this rule shall compile and retain records that provide evidence of control meas ure 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 bei ng applied three times a day and the date) Records

shall be maintained and be re adily 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.
