FACILITY DESCRIPTION

RMC Lonestar operates a portland cement manufacturing facility in

Davenport, California. This facility has been in operation since 1906. The

facility utilizes a Preheater/Precalciner Type Cement Kiln.

Limestone and shale are quarried at the facility location. These quarried

materials along with other purchased raw materials are ground, dried and

supplied in the appropriate chemical proportions to the

preheater/precalciner tower and then to the rotary kiln to produce clinker.

The clinker is cooled, then finish ground with additives in accordance with

the final product's desired properties. The finished product is sacked or

stored in silos prior to bulk shipment by truck or railcar.

The RMC Lonestar Davenport Plant is considered a federal Major Source and

subject to the Title V permitting program due to the potential to emit

Oxides of Nitrogen (NOx), Oxides of Sulfur (SOx), Carbon Monoxide (CO), and

Particulate Matter less than 10 microns in diameter (PM10).

GENERAL CONDITIONS

49. RMC Lonestar shall comply with all conditions of this federal operating

permit. Any noncompliance with a permit condition constitutes a violation

of the Federal Clean Air Act and is grounds for enforcement action; for

permit termination, revocation and reissuance, or modification; or for

denial of a permit renewal application. [District Rule 218]

50. In an enforcement action, the fact that RMC Lonestar would have to halt

or reduce the permitted activity in order to maintain compliance with the

conditions of this permit is not a defense. [District Rule 218]

51. This permit may be modified, revoked, reopened and reissued, or

terminated for cause as determined by the District. The filing of a request

by RMC Lonestar for a permit modification, revocation and reissuance, or

termination, or of a notification of planned changes or anticipated

noncompliance does not stay any permit condition. [District Rule 218]

52. This permit does not convey any property rights in either real or

personal property, or any exclusive privileges, nor does it authorize any

injury to private property or any invasion of personal rights, nor any

infringement of federal, state, or local laws or regulations. [District

Rule 218]

53. RMC Lonestar shall furnish to the District, within a reasonable time,

any information that the District may request in writing to determine

whether cause exists for modifying, revoking and reissuing, or terminating

the permit, or to determine compliance with the permit. Upon request, RMC

Lonestar shall also furnish to the District copies of records required to

be retained by this permit. [District Rule 218]

54. For applicable requirements that will become effective during the

permit term, RMC Lonestar shall meet such requirements on a timely basis

unless a more detailed schedule is expressly required by the applicable
requirement. [District Rule 218]

55. Any document submitted to the District pursuant to this permit shall

contain certification by the responsible official of truth, accuracy and

completeness. All certifications shall state that based on information and

belief formed after reasonable inquiry, the statements and information in

the document are true, accurate, and complete. RMC Lonestar shall promptly,

upon discovery, report to the District a material error or omission in

these records, reports, plans, or other documents. [District Rule 218]

56. RMC Lonestar shall report any violation of any requirement contained in

this permit to the District within 96 hours after such occurrence. The

violation report shall include the time intervals, date and magnitude of

excess emissions; nature and cause of the excess (if known), corrective

actions and preventive measures adopted. [District Rule 218]

57. Upon any administrative or judicial challenge, all the emission limits,

specific and general conditions, monitoring, record keeping, and reporting

requirements of this permit, except those being challenged, remain valid

and must be complied with. [District Rule 218]

58. For this federal operating permit to remain valid through the permit

term of five years from the date of issuance, RMC Lonestar shall pay an

annual emission fee based upon the requirements of District Rule 308.

[District Rule 218]

59. RMC Lonestar shall have available at the facility at all times a copy

of this federal operating permit. [District Rule 218]

60. For protection from enforcement action based upon an emergency, as

defined in District Rule 218, the responsible official for RMC Lonestar

shall submit to the District relevant evidence which demonstrates [District

Rule 218]:

a) an emergency occurred; and

b) that RMC Lonestar can identify the cause(s) of the emergency; and

c) that the facility was being properly operated at the time of the

emergency; and

d) that all steps were taken to minimize the emissions resulting from the

emergency; and

e) within two working days of the emergency event, RMC Lonestar provided

the District with a description of the emergency and any mitigating or

corrective actions taken.

61. Upon presentation of credentials, RMC Lonestar shall allow the

District, the ARB, the EPA, or an authorized representative, to perform the

following [District Rule 218]:

a) enter upon the premises where the federal operating permit source is

located or in which any records are required to be kept under the terms and

conditions of this federal operating permit;

b) to have access to and copy any records required to be kept under the
terms and conditions of this federal operating permit;

c) to inspect any equipment, operation, or process described or required in

this federal operating permit; and,

d) to sample emissions from the source.
