Potential Exposure Pathways Sample Clauses

Potential Exposure Pathways. Based on NASA’s planned land use for the NRP area, potential future receptors identified in the Revised HHRA include (a) construction workers; (b) indoor workers, such as researchers, teachers, office personnel; and (c) adult and child residents in housing provided for students or employees and their families (Mactec, 2003b). For the adult and child residents, exposures were assessed in two ways, i.e., assuming a typical 5- to 10- year residence at the Site, and assuming a 30-year residence at the Site, which is consistent with default exposure parameters in U.S. EPA risk assessment guidance. Potential future receptors may be exposed to COPCs by one or more of the following pathways: • inhalation of volatile chemicals from groundwater or soil; • dermal absorption due to direct soil and/or groundwater contact; • inhalation of airborne suspended soil particulates; and • incidental soil ingestion. These pathways are described more fully below. VOCs are the primary COPCs found within the NRP area. VOCs in groundwater and soil can volatilize into the pore spaces within unsaturated zone soils and migrate through the soil column and through cracks in floors into enclosed indoor spaces, where they can be inhaled by potential receptors. The migration of COPCs from the subsurface into indoor air is called “vapor intrusion”. This is the primary potentially complete exposure pathway that could affect future indoor workers, residents, students, or visitors to the NRP. This mechanism is illustrated on Figure 8 and discussed further in Section 5.1.1. The same mechanism can also lead to exposure to COPCs in ambient outdoor air; however, due to dilution by typical winds in the area, potential exposures are much less than in enclosed spaces. Construction workers may also be exposed to COPCs through the inhalation pathway during soil excavation or trenching activities that may expose soil or groundwater containing COPCs directly to ambient air leading to increased volatilization of COPCs. Exposure to COPCs can also occur through dermal absorption due to direct contact with soil or groundwater containing COPCs. COPCs can then be absorbed through the skin. This potentially complete exposure pathway could affect construction workers at the Site, particularly when excavation or trenching or other activities involve disturbance of the subsurface and expose workers to direct contact with soil or groundwater containing COPCs.

  • Circumstances Affecting LIBOR Rate Availability In connection with any request for a LIBOR Rate Loan or a conversion to or continuation thereof, if for any reason (i) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Loan, (ii) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that reasonable and adequate means do not exist for the ascertaining the LIBOR Rate for such Interest Period with respect to a proposed LIBOR Rate Loan or (iii) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the LIBOR Rate does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Loans during such Interest Period, then the Administrative Agent shall promptly give notice thereof to the Borrower. Thereafter, until the Administrative Agent notifies the Borrower that such circumstances no longer exist, the obligation of the Lenders to make LIBOR Rate Loans and the right of the Borrower to convert any Loan to or continue any Loan as a LIBOR Rate Loan shall be suspended, and the Borrower shall either (A) repay in full (or cause to be repaid in full) the then outstanding principal amount of each such LIBOR Rate Loan together with accrued interest thereon (subject to Section 5.1(d)), on the last day of the then current Interest Period applicable to such LIBOR Rate Loan; or (B) convert the then outstanding principal amount of each such LIBOR Rate Loan to a Base Rate Loan as of the last day of such Interest Period.

  • Provisions Related to Extended Revolving Credit Commitments If the maturity date in respect of any tranche of Revolving Credit Commitments occurs prior to the expiration of any Letter of Credit, then (i) if one or more other tranches of Revolving Credit Commitments in respect of which the maturity date shall not have occurred are then in effect, such Letters of Credit shall automatically be deemed to have been issued (including for purposes of the obligations of the Revolving Credit Lenders to purchase participations therein and to make Revolving Credit Loans and payments in respect thereof pursuant to Section 2.03(d)) under (and ratably participated in by Lenders pursuant to) the Revolving Credit Commitments in respect of such non-terminating tranches up to an aggregate amount not to exceed the aggregate principal amount of the unutilized Revolving Credit Commitments thereunder at such time (it being understood that no partial face amount of any Letter of Credit may be so reallocated) and (ii) to the extent not reallocated pursuant to immediately preceding clause (i), the Borrower shall Cash Collateralize any such Letter of Credit in accordance with Section 2.17. If, for any reason, such Cash Collateral is not provided or the reallocation does not occur, the Revolving Credit Lenders under the maturing tranche shall continue to be responsible for their participating interests in the Letters of Credit. Except to the extent of reallocations of participations pursuant to clause (i) of the second preceding sentence, the occurrence of a maturity date with respect to a given tranche of Revolving Credit Commitments shall have no effect upon (and shall not diminish) the percentage participations of the Revolving Credit Lenders in any Letter of Credit issued before such maturity date. Commencing with the maturity date of any tranche of Revolving Credit Commitments, the sublimit for Letters of Credit shall be agreed with the Lenders under the extended tranches.

  • Laws Affecting LIBOR Rate Availability If, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Offices) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Offices) to honor its obligations hereunder to make or maintain any LIBOR Rate Loan, such Lender shall promptly give notice thereof to the Administrative Agent and the Administrative Agent shall promptly give notice to the Borrower and the other Lenders. Thereafter, until the Administrative Agent notifies the Borrower that such circumstances no longer exist, (i) the obligations of the Lenders to make LIBOR Rate Loans and the right of the Borrower to convert any Loan or continue any Loan as a LIBOR Rate Loan shall be suspended and thereafter the Borrower may select only Base Rate Loans hereunder, and (ii) if any of the Lenders may not lawfully continue to maintain a LIBOR Rate Loan to the end of the then current Interest Period applicable thereto as a LIBOR Rate Loan, the applicable LIBOR Rate Loan shall immediately be converted to a Base Rate Loan for the remainder of such Interest Period.
