This Flood Insurance Study (FIS) may not contain all data available within the repository. It is advisable to contact the community repository for any additional data. Part or all of this FIS may be revised and republished at any time. In addition, part of this FIS may be revised by the Letter of Map Revision (LOMR) process, which does not involve republication or redistribution of the FIS. It is, therefore, the responsibility of the user to consult with community officials and to check the community repository to obtain the most current FIS components. Initial County FIS Effective Date: June 4, 2007 Revised Countywide FIS Date: April 3, 2020 – To add Base Flood Elevations and Special Flood Hazard Areas; to change Base Flood Elevations, Special Flood Hazard Areas, and zone designations; to updated roads and road names; and to reflect updated topographic information.

It began as a small brownstone holousu e thai was later entirely encased in future wooden additions. The house stood near the banks the Passaic R.ver near the Clifton town line and was once a rest stop for travelers. Contents Acknowledgments 6 Introduction 7 1. Quarries, Mills, and Factories 9 2.

    Former Givaudan Facility CA725 Page 1 DOCUMENTATION OF ENVIRONMENTAL INDICATOR DETERMINATION RCRA Corrective Action Environmental Indicator (EI) RCRIS Code (CA725) Current Human Exposures Under Control Facility Name: Givaudan Roure Corporation Facility Address: 125 Delawanna Avenue, Clifton, New Jersey Facility EPA ID#: NJD002156354 Definition of Environmental Indicators (for the RCRA Corrective Action) Environmental Indicators (EIs) are measures being used by the Resource Conservation and Recovery Act (RCRA) Corrective Action program to go beyond programmatic activity measures (e.g., reports received and approved) to track changes in the quality of the environment. The two EIs developed to date indicate the quality of the environment in relation to current human exposures to contamination and the migration of contaminated groundwater. An EI for non-human (ecological) receptors is intended to be developed in the future. Definition of “Current Human Exposures Under Control” EI A positive “Current Human Exposures Under Control” EI determination (“YE” status code) indicates that there are no unacceptable human exposures to “contamination” (i.e., contaminants in concentrations in excess of appropriate risk-based levels) that can be reasonably expected under current land- and groundwater-use conditions (for all contamination subject to RCRA corrective action at or from the identified facility [i.e., site-wide]). Relationship of EI to Final Remedies While final remedies remain the long-term objectives of the RCRA Corrective Action program, the EIs are near-term objectives, which are currently being used as program measures for the Government Performance and Results Act of 1993 (GPRA). The “Current Human Exposures Under Control” EI is for reasonably expected human exposures under current land- and groundwater-use conditions ONLY, and does not consider potential future land- or groundwater-use conditions or ecological receptors.
