Management of Material with Previously Unknown Hazardous Substances Clause Samples

Management of Material with Previously Unknown Hazardous Substances. If the Proponent encounters a previously unknown occurrence of hazardous substances at concentrations greater than applicable cleanup levels and those materials possess field- screening indications of gross contamination (e.g., odor or presence of visible non- aqueous phase liquid (NAPL)), then the Proponent must notify Ecology and the Port contacts in Section 3.1 of the occurrence within 3 business days. Hazardous substances known to exceed cleanup levels within soil or groundwater of the PTM ▇▇▇ include petroleum hydrocarbon, metals, VOCs, PAHs, dioxins/furans, and acidic pH. Aspect (2013) and Aspect (2014) provide additional details regarding hazardous substances within the PTM ▇▇▇, and are incorporated here by reference. After notifying the Port and Ecology, such materials excavated for project purposes must be segregated and managed separately from materials without indications of gross contamination. Excavated materials with indications of gross contamination must be either: (1) properly profiled and disposed of off site in accordance with procedures identified in Section 3.2.3; or (2) sampled to characterize the contamination as described below, and the information presented to Ecology for their determination on its suitability for on-site reuse beneath the ▇▇▇-wide cap. To chemically characterize material containing gross contamination for potential on-site reuse, one representative 5-point composite sample will be collected for each 20 cubic yards of material with indications of gross contamination, using industry-standard sampling practices for the material being sampled and the contaminants being analyzed for (listed below). The material may be sampled in situ (that is, before excavation/grading) or sampled from a stockpile after excavation/grading. Each sample must have a unique identification number and, for each sample, the correlation between the identification number and the stockpile or in situ location from which it was collected must be recorded. Characterization soil samples must be submitted under chain of custody to an Ecology-accredited analytical laboratory for the following chemical analyses: • Diesel-range and oil-range petroleum hydrocarbons (by NWTPH-Dx method with silica gel pretreatment); • VOCs by EPA Method 8260; and • The metals arsenic, cadmium, chromium, copper, lead, mercury, nickel, and zinc (by EPA Methods 6000 and 7000).

  • No Hazardous Materials (A) have been disposed of or otherwise released from any Real Property of the Company or any of its Subsidiaries in violation of any Environmental Laws; or (B) are present on, over, beneath, in or upon any Real Property or any portion thereof in quantities that would constitute a violation of any Environmental Laws. No prior use by the Company or any of its Subsidiaries of any Real Property has occurred that violates any Environmental Laws, which violation would have a material adverse effect on the business of the Company or any of its Subsidiaries.

  • 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 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.

  • 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.

  • 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.
