2019 Comprehensive Annual Financial Report (CAFR)
In November 2005, the City issued $8.4 million in Special Obligation bonds for the purpose of constructing a solid waste transfer facility. This facility, which opened in 2006, is located in an industrial section of western Greensboro and accepts waste from the City’s solid waste collection services and from private haulers, with waste transported off-site daily to a private site outside of the City. It is expected that White Street Landfill will only be utilized for disposal of construction, demolition debris, yard waste and certain incinerated waste and in the event that the transfer station is not operational. The estimated liability amounts are based on what it would cost to perform all closure and postclosure care in the current year. Actual costs may be higher due to inflation, changes in technology, or changes in regulations. At June 30, 2019, the City had expended $3,876,035 to complete closure of the White Street facility, Phase II and $2,535,980 to begin closure activities at the construction and demolition site located on top of the municipal waste filled space. The balance of closure costs, estimated at $13,934,794 and an estimated $13,225,763 for postclosure care will be funded over the remaining life of the landfill, estimated to be 20 to 25 years. E. Pollution Remediation Obligations Greensboro staff have identified specific City-owned properties where either it is known or reasonably believed that the sites contain certain pollutants. Most of the properties have not completed an environmental assessment of the impact or have active remediation systems in place, however each site has been reported to a North Carolina regulatory agency as having a current or reportable incident, thus voluntarily obligating the City for certain remediation activities. In addition, the City entered an administrative agreement with a state agency to voluntarily assess a site. None of the reported pollution creates an imminent endangerment to public health or welfare and many of the sources of impact have already been eliminated, as reasonably appropriate. An estimated pollution remediation obligation of $1,553,535 is recorded in the Statement of Net Position in the Solid Waste Management Enterprise Fund. This amount reflects current estimates for groundwater pollution remediation noted at the City’s White Street landfill, in an active part of the disposal site, not associated with closure and postclosure activities. City staff has voluntarily worked with appropriate State regulators to assess the environmental impact and to develop a corrective action plan. The estimated cost of remediation is based on an external consultant’s estimate for the corrective action plan, which involves phyto-remediation and monitored natural attenuation activities. Should further activities become necessary, such as constructing a pump and treat system, cost estimates would then be re-evaluated. Remediation activities began in Fiscal Year 2010 and are ongoing. Additional pollution remediation activities have been identified by the City relating to a former industrially-impacted property purchased in 1999 to house certain public safety and Water Resources operations. A Phase I Remedial Assessment was prepared by an external consultant in 2019 that focused on groundwater contamination. As of June 30, 2019, the City recorded an estimated pollution remediation obligation of $2,736,292 in the Water Resources Enterprise Fund and an additional $1,303,708 in the government-wide financial statements for public safety operations. City officials deem use of biobarrier methods to be the probable course of remediation action. Certain other sites associated with pollution activity within the City have been identified, primarily pertaining to former waste disposal or prior property use; however, costs for remediation activities are not estimable as of June 30, 2019. In addition, we estimate no future recoveries to potentially reduce the recorded pollution liabilities in Fiscal Year 2019.
