Rule 2: Permits Due to the proximity of the Primero Middle/High School and local residences, LCC will record the level of airblast generated from each blast, and maintain copies of these airblast records in accordance with Rule 4.08.5(17). The airblast recording system will be established in the Primero Middle/High School parking lot neazest the blasting. The upper-end and lower-end frequency limits of the airblast monitoring system will be 250 and 2 Hz, respectively. Owners of residences or structures located within''/z mile of the permit boundazy will be notified of the blasting and offered the opportunity to receive pre-blasting surveys. Exhibit "B" on pages 2.05-39e and 2.05-39f is a copy of the notification to be sent annually. LCC will conduct pre- blasting surveys of surface structures upon request by the Division. No blasting will be conducted within 1000 feet of dwellings, schools, hospitals, churches, or nursing homes without prior approval from the Division. Table 2.05.3-3 lists the names and addresses of the residents and owners of dwellings and other structures located within one-half mile of the LCC permit boundazy. At least once each year, Lorencito agrees to initiate the following actions to maintain accurate property ownership records for lands located within one-half mile of the Mine Permit Area. (a) examine the Las Animas County Tax Assessor's records covering ownership of real property located within one-half mile of the mine Permit Area and copy all data covering a change in the ownership information since the last examination was conducted; (b) visit the azea within one-half mile of the Permit Area to determine if any new construction or renovation has occurred since the last visual survey; (c) record and maintain records showing when the examination of the tax assessor's records and the visual survey of the azea within one-half mile of the Permit Area occurred. This information shall be maintained in a sepazate file covering real property ownership changes that occur within one-half mile of the Permit Area. Rule 4.08.4(8) concerns limiting flyrock from blasting to '/z the distance to the nearest residence and/or the property boundary. The nearest residence to mining is neaz Contour Mine Area P2, approximately 1,200 feet away. The property boundary is approximately 50 feet from the northernmost boundazy of P2. In those azeas where blasting cannot be designed to control flyrock according to the rule, LCC will either not mine the azea, or will use dozer ripping or other non-flyrock methods to break rock and coal. As shown on Map 2.05.3-5, there aze several coal-bed methane wells and pipelines within 500 ft of permitted blasting azeas. Table 2.05.3-4 shows the date each coal bed methane well within 500 ft of proposed blasting was completed (based on well records maintained by the Colorado Oil and Gas Conservation Commission). According to Paragraph 15 of Exhibit B of the OIL AND GAS TOP LEASE, dated June 22, 1998, between MGP Enterprises (MGP) and Evergreen Resources, Inc. (Evergreen), Evergreen must suspend operations, shut in wells, and relocate gathering systems upon 120-day notice from LCC that its operations aze coming within 500 ft of their facilities. All coalbed methane facilities such as wells, wellheads, pipelines, and other associated facilities will be removed before blasting operations occur within 500 feet of them. In addition, Paragraph 15 states that both Page 2.05-39, 39a, b, c, d, e, C(Dec.04.02).doc 2.05-39a (Revised 12/11/02) ~~
