10A 6600 6591 Sed level below actual and bottom <br />The Division suggests that sediment markers be installed based on the design capacity <br />of each pond. Then, using the actual top of the riser and lowest hole design <br />information, the sediment level and remaining capacity can be estimated. It may also <br />be of benefit to use stage elevation rather than absolute elevation AMSL. Please <br />review all 1St quarter reports and correct as necessary. <br /> <br />January 7, 2003 <br />The Division of Minerals and Geology has recently completed a thorough review of the <br />as-built certifications received for all sediment ponds built to-date at the Lorencito <br />Canyon Mine. This review was conducted in accordance with along-standing DMG <br />policy regarding professional certification. The significant portion of the policy is stated <br />below in italics for your convenience. <br />The purpose of professional certifications is to certify that roads, ponds, and embankments have <br />been built as designed, and inspected and monitored in accordance with the regulations. The <br />Division has become aware of cases where professional certification has not been timely, <br />appropriate, or acceptable in accordance with the Rules and Regulations for Coal Mining. <br />Three recurrent types of problems are apparent. <br />1. Structures have been certified only as being in compliance with the requirements <br />of the regulations or prudent state-of--the-art, without being certified as having <br />been built in accordance with the approved design. <br />2. Incidences where the structure could not be built as designed due to the <br />topography of the site where the structure was to be placed differing significantly <br />from mapped pre-mining configuration. <br />3. Flawed inspections and certifications due to inadequate professional practices. <br />The purpose of this policy is to emphasize the need for exercising care in professional <br />certification and professional responsibility as required by the Act. <br />An acceptable professional certification contains clear and unambiguous statements presenting <br />the following information, at a minimum: <br />1) A statement of the professional qualifications of the certifying professional <br />2) A citation of the Rule requiring the certification <br />3) A specific description of the subject of the certification <br />4) A statement of the actions taken in preparing the certification, including such things as <br />inspections performed (date, time, weather and methods), laboratory or field testing preformed, <br />plan or permit documents reviewed, and consultation with other professionals. <br />5) A statement of pertinent professional observations and conclusions made during the <br />completion of the certification. <br />
