NOW, THEREFORE, in consideration of the mutual covenants and obligations of the Parties herein contained, and for other good and valuable considerations, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:
​

Water Softener/Caustic Scrubber Effluent Disposal
​
Lessor shall dispose of Water Softener/Caustic Scrubber Effluent which is delivered by Lessee to Lessor at Lessor’s dust control water sump; provided that in no event shall Lessor be obligated to dispose of Water Softener/Caustic Scrubber Effluent in excess of the quantities set forth in Exhibit “E-2”.  Lessor shall not be required to dispose of Water Softener/Caustic Scrubber Effluent unless the quality of that effluent as delivered meets the quality standards described in Exhibit “E-2” or if such disposal would be inconsistent with any Legal Requirements or Permits applicable to Lessor or would cause Lessor to exceed any quantity or quality standards imposed upon Lessor by any such Legal Requirements or Permits.
​
Lessee shall install, own, operate and maintain, at its sole cost and expense, such equipment as is needed to ensure that Water Softener/Caustic Scrubber Effluent delivered to Lessor meets the quality specifications set forth in Exhibit “E-2”.  Lessor reserves the right to adjust such specifications from time to time as Lessor determines are reasonably necessary to enable Lessor to comply with any Legal Requirements or Permits.  In the event that Lessee delivers Water Softener/ Caustic Scrubber Effluent which fails to meet the quantity and quality specifications set forth in Exhibit “E-2”, Lessee shall immediately notify Lessor of such failure and take such steps as are necessary to prevent the further delivery of such non-conforming Water Softener/Caustic Scrubber Effluent including the transport of the effluent off-site for disposal.  Lessee shall 



promptly reimburse Lessor for all costs, expenses, fees, fines, and penalties, including costs and expenses incurred in the handling and disposing of such non-conforming Water Softener/Caustic Scrubber Effluent already received by Lessor.  In addition, Lessor may, at its election and without any obligation or liability, stop accepting Water Softener/Caustic Scrubber Effluent until Lessor is reasonably satisfied that future Water Softener/Caustic Scrubber Effluent discharges by Lessee shall meet the quantity and quality specifications set forth in Exhibit “E-2”.
​
Water Softener/Caustic Scrubber Effluent Metering and Quality Monitoring
​
Lessee, at its expense, shall provide monthly sampling of the quantity and quality of Water Softener/Caustic Scrubber Effluent.  Lessor may inspect and test all sampling points upon the installation thereof.  In addition, from time to time, Lessor shall be permitted to inspect and test each sampling point upon reasonable advance notice to Lessee.  The cost and expense of any such inspection or test shall be paid by Lessor.  If a sampling device is found to be defective or inaccurate, it shall promptly be adjusted, calibrated, repaired or replaced by Lessee at Lessee’s cost and expense.  If at anytime Lessor desires to independently test the samples, Lessor shall have the right to conduct such testing at its cost.
