the improvement program includes engaging outside experts and consultants who specialize in risk management , reliability , mechanical integrity and psm . we are also recruiting and hiring additional corporate and plant engineering and operational personnel , and accelerating acquisition of additional spare parts to supplement our existing spare parts program . we estimate to incur expenses of approximately $ 1.0 million associated with these programs . the program also includes the installation of additional automation and additional plant equipment protections . also see discussion concerning planned capital expenditures associated with these programs under liquidity and capital resources  capital expenditures . 27 as a result of certain of the events discussed above , we filed insurance claims to recover a portion of the costs incurred and lost profits . see further discussion relating to the downtime of certain chemical facilities and our property and business interruption insurance claims and recovery below under downtime at certain chemical facilities-2012. we are also planning to construct an ammonia plant at the el dorado facility at an estimated cost ranging from $ 250 million to $ 300 million . if constructed , the ammonia plant will produce all of this facility 's ammonia feedstock requirements replacing the ammonia currently being purchased at a cost disadvantage compared to ammonia produced from natural gas . the final decision to construct the ammonia plant is subject to approval of our board of directors , and a number of business considerations , including , but not limited to , obtaining the required permits and adequate third-party financing . an independent engineering firm has been engaged to assist in the preliminary engineering and cost evaluation leading to our final decision . see further discussion relating to capital expenditures and related financing under liquidity and capital resources. economic conditions since our two core business segments serve several diverse markets , we consider fundamentals for each market individually as we evaluate economic conditions . from a macro standpoint , we believe the u.s. economy is poised for modest growth , based upon certain economic reports , including the conference board composite index of leading indicators . chemical businessour chemical business ' primary markets are agricultural , industrial and mining . during 2012 , approximately 46 % of sales were into agricultural markets to customers that purchase at spot market and or futures market prices . during 2012 , our sales volumes to agricultural customers decreased 17 % while sales dollars decreased 6 % compared to 2011. this decrease in sales is primarily the result of the planned and unplanned downtime at certain of our chemical facilities as discussed above partially offset by higher sales prices . in normal circumstances , our agricultural sales volumes and prices depend upon the supply of and the demand for fertilizer , which in turn depends on the market fundamentals for crops including corn , wheat , cotton and forage . the current outlook for 2013 according to most market indicators , including reports in green markets , fertilizer week and the usda 's world agricultural supply and demand estimates , points to positive supply and demand fundamentals for the types of nitrogen fertilizer products we produce and sell . however , it is possible that the fertilizer outlook could change if there are unanticipated changes in commodity prices , fertilizer imports , domestic fertilizer production capacity , acres planted of crops requiring fertilizer , or unfavorable weather conditions . we use natural gas to produce anhydrous ammonia , which ammonia is also used to produce uan . agricultural customer demand for ammonia and uan was strong during 2012. selling prices for ammonia were generally higher while selling prices for uan were slightly less compared to 2011 and the cost for natural gas used to produce these products was generally lower . as a result , gross margins per ton increased for these two products . we produce agricultural grade an from purchased ammonia , which cost is significantly higher compared to previous years and significantly higher than producing it from natural gas , resulting in a cost disadvantage compared to nitrogen fertilizers that can be produced from natural gas . approximately 54 % of our chemical business ' sales were into industrial and mining markets of which approximately 60 % of these sales are to customers that have contractual obligations to purchase a minimum quantity and allow us to recover our cost plus a profit , irrespective of the volume of product sold . during 2012 , our sales volumes to industrial customers decreased 5 % and sales volumes to mining customers decreased 24 % , as compared to 2011. sales dollars during 2012 increased slightly to industrial customers and sales dollars to mining customers decreased 19 % as compared to 2011. the slight increase in industrial sales was due to our ability to pass through higher cost ammonia with our contractual pricing . mining sales were lower due , in part , to the unplanned downtime at our el dorado and cherokee facilities as discussed below under downtime at certain chemical facilities2012 and due to lower customer demand , which we believe is due to higher coal inventories and natural gas being a more attractive alternative feedstock than coal for utility companies . climate control businesssales for 2012 were 5 % lower than the same period in 2011 , including an 11 % decrease in geothermal and water source heat pump sales partially offset by a 3 % increase in hydronic fan coil and a 10 % increase in other hvac sales . from a market sector perspective , the sales decline is due to a 21 % decrease in residential product sales and a slight decrease in sales of commercial/institutional products although sales of our custom air handlers increased . story_separator_special_tag we received correspondence associated with the $ 20 million received in january 2013 , which stated that our insurance carriers are still investigating the circumstances surrounding this event ( including the cause of this event , scope of our losses and support for our claim ) under a reservation of rights . for financial reporting purposes , we allocated $ 28.6 million to our property insurance claim and $ 11.4 million to our business interruption claim primarily based on the claims information provided to our insurance carriers in relation to our requests for insurance proceeds . the $ 28.6 million allocated to the property insurance claim was applied against the recoverable costs totaling $ 21.7 million . the insurance recovery in excess of the recoverable costs of $ 6.9 million was not recognized since it is considered a gain contingency , which will be recognized if , and when , realized or realizable and earned . the insurance recovery of $ 11.4 million allocated to the business interruption claim was applied against recoverable costs ( primarily relating to purchased product sold to our customers while certain of our nitric and sulfuric acid plants were being repaired ) totaling $ 7.3 million as a reduction to cost of sales . the insurance recovery in excess of recoverable costs of $ 4.1 million was not recognized since a portion of this amount relates to recoverable costs , which we were unable to conclude that it was at least probable ( for financial reporting purposes ) that these costs would be approved and a portion of this amount relates to lost profits , which is considered a gain contingency . the unrecognized portion of this recovery , and any additional recoveries , will be recognized if , and when , realized or realizable and earned . as of december 31 , 2012 , the balance of the insurance claim receivable relating to this event was $ 9.0 million , which consists of the approved payments due from our insurance carriers and allocated to our insurance claim as discussed above . 32 cherokee facilityon november 13 , 2012 , a pipe ruptured within the cherokee facility causing damage primarily to the heat exchanger portion of its ammonia plant . no serious injuries or environmental impact resulted from the pipe rupture . as a result of the damage , the cherokee facility can only produce , on a limited basis , nitric acid and an solution from purchased ammonia until the repairs are completed . currently , we expect the cherokee facility to be in full production during may 2013. for 2012 , we believe the cumulative adverse impact to operating income for the unplanned downtime at the cherokee facility was approximately $ 13 million including lost absorption and gross profit margins . a notice of insurance claims for property damage and business interruption was filed with the insurance carriers but the total amounts have not been determined but are expected to be substantial . our insurance policy provides , for the policy period covering this claim , for repair or replacement cost coverage relating to property damage with a $ 2.5 million deductible and provides for business interruption coverage for certain lost profits and extra expense with a 30-day waiting period . because our assessment that it was probable that the amount of coverage for property damages would exceed our property loss deductible , the net book value of the damaged property and other recoverable costs incurred through december 31 , 2012 , we did not recognize a loss relating to property damage from this pipe rupture but we recorded an insurance claim receivable relating to this event consisting of the recoverable costs . in addition , a recovery for certain lost profits from our business interruption coverage has not been recognized since it is considered a gain contingency , which will be recognized if , and when , realized or realizable and earned . as of december 31 , 2012 , the balance of the insurance claim receivable relating to this event was $ 1.1 million consisting of recoverable costs . it is possible that the actual development of the insurance claims discussed above could be different from our current allocations and estimates . due to the increase in the total value of property , plant and equipment ( pp & e ) and the insurance claims discussed above relating to our chemical business , our insurance premiums have increased and could increase in 2013. story_separator_special_tag style= `` font-family : times new
