§ 54-151. Completion of landfill.

(a)

Requirements. When the permittee decides to temporarily or permanently suspend disposal operations at a particular site, the permittee shall within 20 days so notify the city. The permittee shall not remove equipment from the site prior to approval by the city. The city shall direct the permittee to perform corrective work at the site when such work is required in order to fulfill the requirements of this article. The corrective work, if required, shall be completed before the landfill operation is suspended, or accepted as completed. An insect and rodent control program may be required as part of the completion work. A suitable bond may be required by the city to guarantee such completion and maintenance.

(b)

Repair. The permittee shall repair all cracking, eroded, and uneven areas in the final cover, which occur during a ten-year period following completion of the landfill. During this period, the cover surface shall be retopsoiled and reseeded if insufficient vegetation exists to stabilize the surface.

(c)

Monitoring program. The monitoring program shall be as follows:

(1)

Groundwater and surface water. A sample of groundwater shall be collected from each and every monitor well, points of discharge of intercepted groundwater (springs) and surface water bodies prior to the beginning of any landfill operations. These samples shall be analyzed for iron, chloride, hardness of CaCO ₃ , sulfate, nitrates, chemical oxygen demand (COD), total dissolved solids (TDS) and pH and any others as required by the city engineer. These initial samples will serve as background data against which future samples can be compared. All monitoring points shall be sampled and tested for the required parameters every three months and/or more or less frequently should the need be demonstrated. The depth to the water table from a point of known elevation shall be measured and recorded in all monitor wells prior to the collection of each water quality sample. Wells shall be pumped for five minutes prior to sampling. Additional guidelines for monitoring well installation and sampling may be promulgated by the city council. Should any samples appear to have been influenced by the landfill operation, additional sampling, monitoring points and wells, and analysis may be required. The monitoring and analysis program shall be continued for at least five years following completion of the landfill or longer period if required by the city council. The permittee shall submit the results of all analysis to the city not later than 30 days after sample collection. Additional monitoring wells may be required when the initial monitoring wells indicate a change in the groundwater flow system and/or quality of the water.

(2)

Decomposition gases. When monitoring points for decomposition gases are required in the landfill, the permittee shall maintain them and for at least five years following completion or a longer period if required by the city council. The permittee shall submit quarterly gas composition data to the city. The city may require quarterly gas generation rate data.

(3)

Leachate. The permittee shall maintain and operate the leachate collection and treatment system at the completed landfill for at least five years following completion or a longer period if required by the city council. The permittee shall submit leachate quantity and quality data to the city council for those parameters and at such frequencies as specified by the city council.
