Relief Xxxxx. (1) Drilling of a relief well may be commenced without first securing a permit if such action is deemed necessary in the good faith opinion of the operator. The operator shall make all reasonable efforts to notify the superintendent by telephone as soon as feasible, but failure to make such notification shall not be deemed a violation of this article. Within twenty-four (24) hours thereafter, the operator drilling the same shall notify the superintendent that such operations have been commenced, stating fully the reasons therefore, and shall within five (5) days after commencement of operations make application to the superintendent for a special permit to drill such well as a "relief well."
Relief Xxxxx. The drilling of relief xxxxx under this Drilling Contract, subject to the consent and approval of Contractor’s insurance underwriters or their designated marine surveyors, shall be by mutual agreement of Operator and Contractor depending on the particular facts and circumstances of any such relief well and the blowout or other cause necessitating same, and Operator shall reimburse Contractor for any additional or increased premiums assessed by Contractor’s insurers.
Relief Xxxxx. Relief well access points must be maintained so that cover plates can be easily removed for inspection of the tees and surrounding piping. The outfall structures must be kept clear of debris or other material that may affect the operation of the outlet pipe flap gates. The relief xxxxx should be pump-tested, swabbed/cleaned, and sounded by the LMA every five years using the procedures outlined in USACE EM 0000-0-0000, Chapter 8. The purpose of these tests is to measure the efficiencies and flow capacities of the xxxxx and to determine whether sediment or other debris have been deposited in the xxxxx. All xxxxx requiring sediment removal must be pump-tested after sediment has been removed to confirm that the well efficiency has not decreased by more than 20 percent due to the presence of foreign material in the well. During pump tests, runoff must be directed through the lateral pipes toward the outfall structures in order to check that the lines are free of blockages and that the flap gates function properly. Sediment amounts in the relief xxxxx must be measured by sounding a well before and after pump tests. If significant algae or other biological growth is suspected within a well, it must be cleaned as described in USACE EM 0000-0-0000. If efficiencies are less than 80 percent of those recorded at the time of installation, corrective measures per USACE EM 0000-0-0000, Chapters 10 and 11 should be employed. If corrective measures are implemented but do not improve performance to at least 80 percent of the original efficiency, the well should be replaced. Any items that are malfunctioning or have been damaged must be replaced by the LMA. Any condition that prohibits flow into or out of relief xxxxx could result in potentially unstable and hazardous conditions. Malfunctioning and damage to the relief xxxxx can be caused by vandalism, breakage, or excessive deformation of the well screens due to ground movements, corrosion or erosion of the well screen. Repairs to relief xxxxx should be made in accordance with USACE EM 0000-0-0000. Reliefwells must be replaced upon reaching 50 years of service life. If non-functioning relief xxxxx cannot be repaired and are found to be no longer acceptable due to collapse, excessive sediment production or other conditions, they should be properly abandoned and replaced. Abandoned xxxxx should be sealed following procedures established by Yuba County and the California Water Well Standards (Bulletins 74-90 and 74-81). New we...
