SITE CONDITIONS AND BACKGROUND CERCLIS # LAD052510344 Category of removal: Time-Critical Site ID #DF A. Site Description 1. Removal site evaluation The Delatte Metals-North Ponchatoula Battery Site is an aggregation of the inactive Delatte Metals facility and the abandoned North Ponchatoula Battery Site. The Delatte Metals facility consists of approximately 17.6 acres of land at 19113 Weinberger Road (previously 1540 Weinberger Road), Ponchatoula, Louisiana, in Tangipahoa Parish. The facility began battery recycling and smelting operations during the 1960's under the name Delatte and Fuscia Battery Co. In the early 1980's the facility name was changed to Delatte Metals, Inc., with Mr. Larry Delatte its sole owner and president. Delatte Metals shut down smelting operations in June 1992 . There is a long history of releases from and enforcement actions against the Delatte Metals facility. Examples include releases of lead, cadmium and arsenic to surrounding residential properties. There are also documented releases of both acidic and metallic wastes into Selser's Creek, surface discharge of caustic water (pH 13), and an unpermitted injection of caustic water in an attempt to neutralize acidic groundwater. In March 1994 the Louisiana Department of Environmental Quality (LDEQ) Hazardous Waste Division issued an Administrative Order to Delatte Metals regarding control and remediation of waste piles at the facility. A July 1994 Environmental Protection Agency (EPA) Region 6 Resource Conservation and Recovery Act (RCRA) compliance inspection revealed numerous violations, including unpermitted hazardous waste storage, failure to submit annual or biannual reports, inadequate closure plans, and inadequate financial assurances for closure. In March 1995, LDEQ denied Delatte's Hazardous Waste operating permit application. Although smelting operations have ceased, limited operation as a scrap dealer continues. In March 1996 LDEQ Hazardous Waste Division referred the Delatte Metals site to LDEQ's Inactive and Abandoned Sites Division (IASD) which referred the Delatte Metals site to the EPA Site Assessment Section in June 1996. The EPA completed a Site Investigation for the Delatte Metals site in March 1997, and began an Expanded Site Inspection in October 1997. Ponchatoula Battery was a battery recycling facility from the mid 1960's to 1981. During the 1960's the facility was located on 3.7 acres of land on the south side of Weinberger Road (the South Ponchatoula Battery site). Ponchatoula Battery moved its operation to the north side of Weinberger Road in the 1970's, on property adjacent to the Delatte Metals facility (the North Ponchatoula Battery site). Operations at both locations included battery breaking, resale of lead plates and plastic casings, and acid neutralization. Ponchatoula Battery ceased operations in late 1981, claiming inability to comply with state and Federal regulations. In late 1982, Ponchatoula Battery Company conducted a cleanup action at the North Ponchatoula Battery location that included closure of surface impoundments and removal of battery casings and contaminated soil. The Ponchatoula Battery Company filed for bankruptcy in 1985. A second cleanup of the North Ponchatoula Battery location was conducted in 1987 to remove the remaining battery casings. According to LDEQ's 1992 RCRA Facility Assessment report for Delatte Metals, "present standards for clean closure are stricter than those that were applied to this site". In 1993 the EPA Region 6 Alternative Remedial Contracting Strategy (ARCS) contractor conducted an Expanded Site Investigation (ESI) at the Ponchatoula Battery Site. Soil lead concentrations up to 156,000 parts per million (ppm) were detected, but the site did not score high enough to be evaluated further as a potential National Priorities List (NPL) site. Between 1994 and 1995 the EPA Region 6 Technical Assistance Team (TAT) contractor conducted removal assessment to delineate the extent of contamination at the Ponchatoula Battery Site, and the EPA Region 6 Response and Prevention Branch (RPB) conducted a time-critical removal action at the South Ponchatoula Battery location between 1996 and 1997. The North Ponchatoula Battery location was not addressed because of concerns ofrecontamination from the Delatte Metals site. In November 1996 LDEQ requested that EPA regard Ponchatoula Battery and Delatte Metals as a single unit, to avoid recontamination problems during remediation and attribution problems in site ranking. The Site is proposed for listing on the National Priorities List. 2. Physical location The Delatte Metals/North Ponchatoula Battery Site is approximately 5.5 miles south- southeast ofHammond, Louisiana, and 1.5 miles southeast of Ponchatoula, Louisiana. The site lies to the north ofWeinberger Road, in a rural area with numerous residences within a one-mile radius of the site. A site location map of the facility is included as attachment 2. The surrounding area is used for growing crops such as bell peppers, strawberries and soybeans. Minor amounts of land are used for harvesting timber. The March 1997 Site Inspection Report for Delatte Metals included an Environmental Justice Report. A copy of this report is included as Attachment 7. Ponchatoula is the host to the annual Louisiana Strawberry Festival. Tangipahoa Parish covers 783 square miles and has a population of about 85,707. Ponchatoula has a population of about 5,425 and the nearby city ofHammond has a population of about 15,871. The site is bounded by Weinberger Road and residences to the south, drainage ditches and residences to the north and east, and Selser's Creek and a residence to the west. 3. Site characteristics The Delatte Metals/North Ponchatoula Battery site sits on approximately 21.3 acres on the north side ofWeinberger Road. A map, included as Attachment 3, shows the general layout of the site. A two-story brick building immediately north and west ofWeinberger Road is a combination facility business office and residence. A chain link fence bounds the southern edge of the facility north of the facility offices. Most of the soil covering the site is contaminated with lead levels averaging 8000 ppm on the surface and decreasing at depth. Battery chips are visible in soil throughout the site. Rainwater leaching through the waste piles on site probably carries lead, cadmium and arsenic into the soil. Two office-type fixed trailers are directly north and west past the chain link fence. Beyond the trailer offices is an 8,000 square foot building (designated as the "Maintenance Building" for assessment purposes) where the facility actively received batteries and scrap during its operation. The building currently contains assorted debris and small quantities of lubricating oil. An acid tank farm on the facility contains five tanks. Three 2000- gallon capacity upright tanks contain low-pH acidic liquids (sulfuric acid). Two horizontal tanks in the tank farm, approximately 2500 gallons each in capacity, are empty. The Battery Saw Building covers approximately 33,000 square feet and contains the battery breaking and sawing equipment from the facility former operations. The building also contains several piles of mixed fines (particles less than .075 millimeters in diameter), debris and battery chips, and drums of organic liquids. The Settling Basin sits under an open sided tin roof and contains some settled fine solids and some equipment. The Furnace Building, which houses the actual smelter, smelting equipment and the 13 0-foot smelter stack, is very deteriorated, with a rusted and dilapidated roof. The Furnace Building contains approximately 70 tote bags of smelter ash from the pollution control equipment, drums of granular solids, hags of firing range bullet sand, debris and scrap metal. Slag Pile #1 contains approximately

    Production of Dialdehyde Cellulose and Periodate Regeneration: Towards Feasible Oxidation Processes

    Production of Dialdehyde Cellulose and Periodate Regeneration: Towards feasible oxidation processes Produktion av dialdehydcellulosa och återgenerering av perjodat: Mot möjliga oxidationsprocesser Elisabeth Höglund Department of Engineering and Chemical Sciences Chemistry 30 hp Supervisors: Susanne Hansson, Stora Enso & Gunilla Carlsson, Karlstad University Examinator: Thomas Nilsson 2015-09-25 ABSTRACT Cellulose is an attractive raw material that has lately become more interesting thanks to its degradability and renewability and the environmental awareness of our society. With the intention to find new material properties and applications, studies on cellulose derivatization have increased. Dialdehyde cellulose (DAC) is a derivative that is produced by selective cleavage of the C2-C3 bond in an anhydroglucose unit in the cellulose chain, utilizing sodium periodate (NaIO4) that works as a strong oxidant. At a fixed temperature, the reaction time as well as the amount of added periodate affect the resulting aldehyde content. DAC has shown to have promising properties, and by disintegrating the dialdehyde fibers into fibrils, thin films with extraordinary oxygen barrier at high humidity can be achieved. Normally, barrier properties of polysccharide films deteriorate at higher humidity due to their hygroscopic character. This DAC barrier could therefore be a potential environmentally-friendly replacement for aluminum which is utilized in many food packages today. The aim of this study was to investigate the possibilities to produce dialdehyde cellulose at an industrial level, where the regeneration of consumed periodate plays a significant role to obtain a feasible process. A screening of the periodate oxidation of cellulose containing seven experiments was conducted by employing the program MODDE for experimental design.

Received: / Accepted: / Published: Abstract: The Briggs-Rauscher (BR) oscillatory reaction is one of the more interesting and colorful oscillatory reactions. It has surpassed the demonstration realm, as it has found use as a method to assess antioxidant capacity. However, this application as an antioxidant assay is limited to water-soluble samples. In the constant search for different, novel applications, we report the effects of various sample solvents on the behavior of the BR reaction. Our investigation looked at how changes in the solvent used to dissolve samples altered the time intervals of BR reaction’s oscillations. The solvents used were ethanol, isopropanol, 1- propanol, acetone, and acetonitrile. Addition of ethanol had no effect on the BR oscillations. Isopropanol, 1- propanol, and acetone shorten the oscillation time. A test using acetonitrile discarded solvent polarity effects. Our results suggest that solvents that accelerate the enol pathway rate affect the oscillations of the BR reaction. Finally, samples can be safely dissolved in ethanol and used in the BR reaction. Keywords: oscillatory reaction, Briggs-Rauscher reaction, solvent variation, and enol pathway. Introduction The Briggs-Rauscher (BR) reaction is an oscillating reaction that changes between two cycles back and forth until it reaches equilibrium.

  • Consideration of Mandatory Fortification with Iodine for Australia and New Zealand Food Technology Report

    Consideration of Mandatory Fortification with Iodine for Australia and New Zealand Food Technology Report

    CONSIDERATION OF MANDATORY FORTIFICATION WITH IODINE FOR AUSTRALIA AND NEW ZEALAND FOOD TECHNOLOGY REPORT December 2007 1 Introduction Food Standards Australia New Zealand is considering mandatory fortification of the food supply in Australia and New Zealand with iodine. Generally, the addition of iodine to foods is technologically feasible. However, in some instances the addition of iodine can lead to quality changes in food products such as appearance, taste, odour, texture and shelf life. These changes will depend on the chemical form of iodine used as a fortificant, the chemistry of the food that is being fortified, the food processes involved in manufacture and possible processing interactions that could occur during distribution and storage. Many foods have been fortified with iodine and the potassium salts of iodine compounds have been used as the preferred form. 2 Forms of Iodine Iodine is normally introduced, or supplemented, as the iodide or iodate of potassium, calcium or sodium. The following table lists different chemical forms of iodine along with their important physical properties.

In this report, 18 updated and targeted technical information is compiled to augment the 1994 Technical Advisory Panel 19 (TAP) Report on iodine in support of the National Organic Standard’s Board’s sunset review of iodine teat 20 dips in organic livestock production. 21 Characterization of Petitioned Substance 22 23 Composition of the Substance: 24 A variety of substances containing iodine are used for antisepsis and disinfection. The observed activity of 25 these commercial disinfectants is based on the antimicrobial properties of molecular iodine (I2), which 26 consists of two covalently bonded atoms of elemental iodine (I). For industrial uses, I2 is commonly mixed 27 with surface-active agents (surfactants) to enhance the water solubility of I2 and also to sequester the 28 available I2 for extended release in disinfectant products. Generally referred to as iodophors, these 29 “complexes” consist of up to 20% I2 by weight in loose combination with nonionic surfactants such as 30 nonylphenol polyethylene glycol ether (Lauterbach & Uber, 2011).

    Estimation of DL-Glyceraldehyde, Dihy Droxyacetone, Methylglyoxal, and Their Mixtures by Oxidation with Sodium Periodate

    Estimation of DL-glyceraldehyde, dihy droxyacetone, methylglyoxal, and their mixtures by oxidation with sodium periodate M. FEDOROŇKO, E. FÜLEOVÄ, and W. DANIELISZYN Institute of Chemistry, Slovak Academy of Sciences, 809 33 Bratislava Received 17 May 1971 Dedicated to the 65th Anniversary of Professor S. Stankovianslcy An anatytical method for the estimation of DL-glyceraldehyde, dihydroxy- acetone, methylglyoxal, and their binary and ternary mixtures by oxidation with sodium periodate in unbuffered aqueous media was worked out. Oxi­ dations proceeded at 70°C during 1 hour. On the basis of chemical equations of oxidation of the individual compounds studied, of the unchanged sodium periodate as well as the produced acids and formaldehyde, mathematical relations were derived for calculation of the concentrations of individual compounds also in the mentioned types of mixtures. The error of estimation of individual compounds in the concentration range 5 — 20 mg did not exceed zz2%. In the case of binary and ternary mixtures for 20 mg sample, when the concentration range of individual compounds was 20—80%, the relative error of their estimation did not exceed ±10%. In this work, also mechanisms of oxidations with sodium periodate of the estimated compounds are dis­ cussed. In our studies of acid-base catalyzed isomerizations of trioses and their dehydration to methylglyoxal [1], we worked out a quick and fairly precise analytical method for the estimation of the mentioned compounds mainly in their mixtures [2]. This Polaro­ graphie method was based on different reactivity of the studied compounds with primary amines. Because the mentioned compounds are significant and frequently occur in mixtures, we looked for another, purely chemical method of their determination side by side.
