Release of Sediment-Bounded Contaminants Sample Clauses

Release of Sediment-Bounded Contaminants. It is assumed the backfilling of sediment from ▇▇▇▇▇▇ barge or TSHD would expose the sediment to the entire water column. While the majority of sediment stays close together, about 3% of sediment would be entrained into the water column. Seawater would act like a solvent to extract contaminants from the entrained sediment. The dissolved contaminants would be carried away by water current, eventually reaching the nearby WSRs through advection and diffusion. To simulate this process, it is conservatively assumed 100% of the contaminants from the entrained sediment would be lost to the water column and the contaminant levels of the sediment would be at the corresponding UCEL for all contaminants. Then an inert tracer dispersion model would be conducted to simulate the dispersion of contaminants. The dilution achieved at the WSRs would then be factored in with the equilibrium concentration of contaminants in seawater to estimate the contaminant concentration at WSRs, for assessment against the proposed assessment criteria shown in Table 5.2. The dredging of marine sediment for the construction of CMPs would also result in disturbance to bottom sediment and potential release of sediment-bounded contaminants. Surface grab sediment samples were collected in mid-2020 to determine the level of contaminants in sediment within the majority of the Study Area. The sediment quality results are presented in Appendix B for reference. The highest contaminant levels among all stations are presented in Table 3.3 alongside with the LCEL and UCEL for comparison. As shown, none of the contaminant levels exceed the

  • Definition of Hazardous Materials For purposes of this Lease, the term “Hazardous Material” or “Hazardous Materials” shall mean any hazardous or toxic substance, material, product, byproduct, or waste, which is or shall become regulated by any governmental entity, including, without limitation, the County acting in its governmental capacity, the State of California or the United States government.

  • HAZARDOUS SUBSTANCE CONDITIONS If a Hazardous Substance Condition occurs, unless Lessee is legally responsible therefor (in which case Lessee shall make the investigation and remediation thereof required by Applicable Requirements and this Lease shall continue in full force and effect, but subject to Lessor's rights under Paragraph 6.2(c) and Paragraph 13), Lessor may at Lessor's option either (i) investigate and remediate such Hazardous Substance Condition, if required, as soon as reasonably possible at Lessor's expense, in which event this Lease shall continue in full force and effect, or (ii) if the estimated cost to investigate and remediate such condition exceeds twelve (12) times the then monthly Base Rent or $100,000 whichever is greater, give written notice to Lessee within thirty (30) days after receipt by Lessor of knowledge of the occurrence of such Hazardous Substance Condition of Lessor's desire to terminate this Lease as of the date sixty (60) days following the date of such notice. In the event Lessor elects to give such notice of Lessor's intention to terminate this Lease, Lessee shall have the right within ten (10) days after the receipt of such notice to give written notice to Lessor of Lessee's commitment to pay for the excess costs of (a) investigation and remediation of such Hazardous Substance Condition to the extent required by Applicable Requirements, over (b) an amount equal to twelve (12) times the then monthly Base Rent or $100,000, whichever is greater. Lessee shall provide Lessor with the funds required of Lessee or satisfactory assurance thereof within thirty (30) days following said commitment by Lessee. In such event this Lease shall continue in full force and effect, and Lessor shall proceed to make such investigation and remediation as soon as reasonably possible after the required funds are available. If Lessee does not give such notice and provide the required funds or assurance thereof within the time period specified above, this Lease shall terminate as of the date specified in Lessor's notice of termination.

  • Use of Hazardous Materials Tenant shall not cause or permit any Hazardous Materials to be used, stored, discharged, released or disposed of in the Premises or cause any Hazardous Materials to be used, stored, discharged, released or disposed of in, on, from, under or about, the Property, or any other land or improvements in the vicinity of the Property. Notwithstanding the foregoing, Tenant may use and store in the Premises such types and quantities of Hazardous Materials as are normally used in connection with Tenant’s permitted use of the Premises and then only in strict accordance with all Applicable Laws, including all Environmental Laws. Within thirty (30) days after the Effective Date, Tenant shall provide Landlord a complete list of all Hazardous Materials (other than standard janitorial and office products) used or stored, and expected to be used or stored, by Tenant or any of Tenant’s Agents at the Premises during the term of the Prior Lease or during the Term of this Lease, which list shall include MSDS sheets for all such Hazardous Materials and shall identify the equipment and systems within the Premises affected by such Hazardous Materials in Tenant’s business operations (“Tenant’s Hazardous Materials Plan”). Throughout the Term on an annual basis and upon Landlord’s written request, Tenant shall continue to update Tenant’s Hazardous Materials Plan so that it remains current. Without limiting the foregoing, Tenant shall, at its own expense, procure, maintain in effect and comply with all conditions of any and all permits, licenses, and other governmental and regulatory approvals required for Tenant’s use of Hazardous Materials at the Premises, including, without limitation, discharge of appropriately treated materials or wastes into or through any sanitary sewer serving the Premises. Tenant shall in all respects handle, treat, deal with and manage any and all Tenant’s Hazardous Materials in total conformity with all Environmental Laws and prudent industry practices regarding management of such Hazardous Materials.

  • Hazardous Substance The term “Hazardous Substance” shall mean any hazardous or toxic substances, materials or wastes, or pollutants or contaminants as defined, listed or regulated by any Environmental Law or by common law decision including, without limitation, chlorinated solvents; petroleum products or by products; asbestos; and polychlorinated biphenyl.

  • Hazardous Substances The words "Hazardous Substances" mean materials that, because of their quantity, concentration or physical, chemical or infectious characteristics, may cause or pose a present or potential hazard to human health or the environment when improperly used, treated, stored, disposed of, generated, manufactured, transported or otherwise handled. The words "Hazardous Substances" are used in their very broadest sense and include without limitation any and all hazardous or toxic substances, materials or waste as defined by or listed under the Environmental Laws. The term "Hazardous Substances" also includes, without limitation, petroleum and petroleum by-products or any fraction thereof and asbestos.
