## A. Site Description 1. Removal SiteEvaluation In 1926, theTexas Electric Steel Casting Company (TESCO) began operations as a metal casting foundry. TESCO primarily manufactured specialty moldedparts such as large wheels, tracks, and mining equipment. The process area consisted ofcasting plants. Both plants maintained separate sand systems, core ovens, mold makes, electric arc furnaces, pouring facilities, andcleaning, annealing and heat treating process areas. During the mid-1980s, the southern portion ofthe Site was leased to Can-Am Resources Group (Can-AM). Can-Am conducted a spentcatalystrecycling operations using an experimental process. Can-Am reportedly obtained between 2,000 and4,000 drums ofspent catalyst from chemical plants and refineries along the Houston Ship Channel. By 1988, Can-Am ceased operations and abandoned the drums ofspentcatalyston the Site. In 1990, MDI bought the TESCO note from the Texas Commerce Bank. TESCO ceased operations in February 1991, and MDI foreclosed on the property. MDI reopened as the San Jacinto Foundry (SJF) on March 1,1991. 

## SJFcontinued operations until about June 1, 1992. MDI filed for Chapter7 Bankruptcy in the U.S. Bankruptcy Court for the Southern District of Texas in May 1992. The onsite facilities were demolished as a salvage operations underthe orderofthe U.S. Bankruptcy Court between March 1995 and January 1996. As a result ofthe operations at the facility, several offsite properties were contaminated with lead above the action level of400 parts permillion (PPM). More than 150 residential yards and the courtyards ofa City ofHouston Housing Authority complex have been addressed by eitherthe State ofTexas orEPA. The owners ofsix additional homes declined to give access or to participate in the previous cleanups. Recently, those owners have chosen to provide access for sampling and cleanup. 2. Physical Location The MDI Site was located at 3617 Baer Streetin Houston, TX. It 

## was an abandoned foundry facility located approximately two miles eastofdowntown Houston nearthe Intersection ofHighway 59 and Interstate 10. This portion ofHouston is known as the "Fifth Ward:' The facility occupied approximately 36 acres in an area ofmixed industrial and residential landuse. It was bounded byHare Street to the north; National VinegarCompany and Press Street to the east; the fonnerTexas 

## & New Orleans Railroadright-of-way beyond the easement to the south; and Bringhurst Street to the west. There are in excess of 10,000 people within a mile ofthe Site, including several hundred children attending the local elementary school. The homes involvedin the response are approximately within 

## Y2 to

# * ofa mile from the facility. The perimeteris representedby the map in Figure 1.

3. Site Characteristics The MDI facility has been purchasedby an unrelatedcompany thathas agreed to conduct the cleanup on the facility perEPA oversight. Plans are to build Condominiums as partofthe revitalization ofthe area and specifically atthe Site. There are approximately 150residential homes and properties that are contaminated above the action level that have been addressedby previous actions. In 

## addition, the nearby BruceElementary School and the Houston Housing Authority's Kelly village, amulti-family apartmentcomplex, have been addressed. An additional 6 homes have recentlyprovided access for sampling andcleanup. This proposedaction will address those homes. 4. Releases orthreatenedrelease into the environmentofahazardous substance, pollutantorcontaminant Leadis the primarycontaminant ofconcern atthe Site. Leadis a designatedhazardous substance as defined in Section 101(140ofCERCLA, 42 U.S.C. §9601(14), and40 CFR §302.4. TCEis ahazardous constituentunder40 C.F.R. Part261. (See

## Previous actions In 1998 and 1999, the Potentially Responsible parties removed over 5,000 drums containing waste materials, with EPA's oversight. Shortly after that the Texas Commission on Environmental Quality (TCEQ) conducted aremoval andrestoration of89 residential yards. In 2003 and 2005, EPA conducted removal actions on homes and a school that were not addressed by the TCEQ action. Those actions addressed approximately 65 homes andresidential lots and the Bruce Elementary School grounds. In 2006, EPA conducted a removal action atthe Houston Housing Authority's Kelly Village. Kelly Village is a multi-family apartmentcomplex. The courtyards and playgrounds with leadcontamination exceeding the action level were excavated andrestored. 2. Current actions The MOl facility is being revitalized by aprivate investorper an agreement with EPA. No actions on the residential properties arecurrently being taken. C. State and Local Authorities' Roles 1. State and local actions to date The State, through theTCEQ conducted aremoval action at the Site in 1999. TCEQ addressed 89 homes before available funding was depleted. 2. Potential for continued StatelLocal response The TCEQ has indicatedthat they do not have the funding for this response.

## III. THREATS TO PUBLIC HEALTH OR WELFARE OR THE ENVIRONMENT, AND STATUTORY AND REGULATORY AUTHORITIES 

## A. Threats to Public Health orWelfare The current c'onditions at the Site meet the following factors which indicate that the Site is athreat to the public health, welfare and the environment and aremoval action is appropriate under Section 300.415(b)(2) ofthe National Contingency Plan. Any or all ofthese factors may be present at the Site yet anyone ofthese factors may determine the appropriateness ofa removal action. I. 

## Actual or Potential Exposure to Nearby Human Populations, Animals, orthe Food Chain from Hazardous Substances orPollutants or Contaminants NCP Section 300.415(b)(2)(i) The soils at the Site contain lead concentrations up to 2,000 ppm. The EPA's goal is to attempt to limit exposure to soil lead levels such that a typical child orgroup ofsimilarly exposed children would have an estimated risk ofno more than 5% ofexceeding a 10 Ilgld1 blood lead level. The 463 ppm removal action level meets the 5% benchmark, based on the experience gained from other lead sites in EPA Region 6. The Centerfor Disease Control (CDC) considers the 10 Ilgldl blood lead level as elevated for young children. The EPA believes that the lead in theses soils is attributable to the historical foundry operations as well as otherpossible sources. 2. High Levels ofHazardous Substances orPollutants orContaminants in Soils Largely At or Near the Surface that MayMigrate. NCP Section 300.415(b)(2)(iv) The concentrations oflead in the soils ofthe homes exceed the 463 ppm actIon level. Lead affects multiple target systems in adults and children. However, young children, generally seven years ofage and younger are at the greatest risk from the effects oflead. Lead can cause damage to the brain and nervous system, slowed growth, and behavioral, learning, and hearing problems. 3. Weather Conditions That May Cause Hazardous Substances or Pollutants or Contaminants to Migrate ofbe Released. NCP Section 300.415(b)(2)(v) The Houston area is subject to frequent heavyrain storms, tornados, flooding and severe hurricanes. Those weatherconditions,can cause the migration ofthe contaminant. 4. The Availabilityofother Appropriate Federal or State Response Mechanisms to Respond to the Release. NCP Section 300.415(b)(2)(vii) There are no other feasible alternative mechanisms to respond to the Site. The State has indicated that they do not have the funds to conduct the removal. The PRPs have declined to take action at the Site

## IV. ENDANGERMENT DETERMINATION Actual or threatened releases ofhazardous substances, pollutants orcontaminants from this Site, ifnot addressed by implementing the response action selected in this Action Memorandum, may present an imminent and substantial endangerment to the public health, welfare, orthe environment.
V. PROPOSED ACTIONS AND ESTIMATED COSTS A. 

## Proposed actions 1. ProposedAction Description The proposed removal action involves the excavation ofthe contaminated soils from parts orthe entire residential yard ofthe six residences. Excavation will be conducted according to the investigation completed on each residence. The excavated areas will bebackfilled to propergrade and restored. The contaminated soil will be transported offsite for disposal at an approved and appropriate facility. 2. Contribution to Remedial Performance The proposed action is consistentwith the remedial. Completion ofthe cleanup at the six residences will allow for the delisting ofthe Site. 3. Description ofAlternative Technologies The alternative to removal ofthe contaminated soil is to use engineering controls such as maintaining grass cover orconcreting the contaminated areas. Those controls will not remove the contamination and will not ensure that future contamination will not occur. Concrete slabs are not acceptable in most areas. The likelihood ofmaintaining the proper grass cover is unlikely. 4. Applicable or Relevant and Appropriate Requirements (ARAR) This removal action will be conducted to eliminatethe actual or potential exposure to hazardous substance, pollutant orcontaminantto the environment, pursuant to CERCLA, 42 V.S.c. §9601 et**~.,** 

## and in a mannerconsistent with the National Contingency Plan (NCP), 40 CFR Part 300, as required at 33 U.S.c. §1321(c)(2) and42 V.S.c. §9605. Pursuant to 40 CFR Part 300.415(j), fund-financed removal actions under CERCLA §104 and removal actions

## pursuant to CERCLA §

## 106 shall, to the extent practicable considering the exigencies ofthe situation, attain the applicable orrelevant and appropriate requirements underFederal environmental law. 5. Project Schedule The action will begin with the documentation ofexisting conditions ateach ofthe residences. Typically, the documentation oftwo residences can be completed in a day. The excavation, backfill and restoration ofthe yards can be accomplished in 3 to 4 days perresidence. If

## additional work is required. such as the replacementofdamaged sidewalks ordriveways, then additional days are expected for those activities. The cleanup is completed with an inspection and acceptance by the property ownerthat all restoration has been completed. B. Estimated Costs Extramural Costs Previous Costs Proposed Ceiling Total Ceiling Forthis action Cleanup Contractor $1.178.314.60 $200,000 $1.378,314.60 START $784,291.02 $80.000 $864,291.02 Miscellaneous $477.51 $477.51 Total Extramural $ 1,963,083.13 $280.000 $2,243,083.13 Site Contingency (15%) $40,000 $40,000.00 TOTAL CEILING $320,000 $2,283,083.13


## VI. EXPECTED CHANGE IN THE SITUATION SHOULD ACTION BEDELAYED ORNOT TAKEN If

## this action is not taken at the Site, residents ofthe homes will continue to be exposed to concentrations oflead above the action level. The neighborhoodhas many children in the most susceptjble range ofage. Those children will continue to 

## be exposed to the lead contaminated soil. The lead may also migrate and result in additional yards to be contaminated.

## VIII. ENFORCEMENT For administrative purposes, information concerning confidential enforcement strategy for this Site is contained in the Enforcement Attachment

## #1. The total costfor this removal action based on'full-cost accounting practices that will be eligible for cost recovery are estimated to be $3,674,975.66 or$526,504.50 for this action alone. (Direct Cost) + (OtherIndirectCosts) 

## +52.61 % of(Total Direct + Indirect Costs) =EstimatedEPA Cost for This Removal Action only. $320,000 + $25,000 + 0.5261($320,000 + $25,000) = $526,504.50 Total cost for the project: $2,283,083.13+ $125,000 + 0.5261($2,283,083.13+ $125,000) = $3,674,975.66 Directcosts include direct extramural costs and direct intramural costs. Indirect costs are calculated based on an estimated indirectcost rated expressed as a percentage ofsite-specific direct costs, consistent with the full cost accounting methodology effective October2,2002. The estimates do not include pre-judgmentinterest, do nottake into account otherenforcementcosts, including Department ofJustice costs, and may be adjusted during the course ofa removal action. The estimates are for illustrative purposes only, and their use is not intendedto create any rights forresponsible parties. Neitherthe lack ofa total costestimate northe deviation ofactual total costs from thisestimate will affect the United States' right to cost recover.


## VIII. RECOMMENDATION This decision document represents the selected removal action for the Many Diversified Interests, Inc. (MDI) Site, Houston, Hartis County, Texas, developed in accordance with CERCLA as amended, and not inconsistentwith the NCP. This decision is based on the administrative record for the Site. Conditions at the Site meet the criteria as defined by 40 CFR Section 300.415(b)(2) ofthe NCP for a removal, and I recommend your approval ofthe proposedremoval action. The total projectceiling for. his action will be $320,000.

# I August 2007 This fact sheet answers the most frequently asked health questions (FAQs) a·bout lead, For more information, call the ATSDR Information Center at**1-800-232~4636.** 

### This fact sheet is one in a series ofsummaries about hazardous substances and their health effects. It 

### is important you understand this information because this substance may harm you. The effects ofexposure to an)' hazardous substance depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other chemicals are present. 

## HIGHLIGHTS: Exposure to lead can happen from breathing workplace air or dust, eating contaminated foods, or drinking contaminated water. Children can be exposed from eating lead-based paint chips or playing in contaminated soil. Lead can damage the nervous system, kidneys, and reproductive system. Lead has been found in at least 1,272 of the 

## 1,684 National Priority List sites identified by the Environmental Protection Agency (EPA).
. What is lead'! Lead is a naturally occurring bluish-gray metal found in small amounts in the earth's crust. Lead can be found in all parts ofour environment. Much ofit comes from human activities including burning fossil fuels, mining, and manufacturing. Lead has many different uses. It is used in the production of batteries, ammunition, metal products (solder and pipes), and devices to shield X-rays. Because ofhc;alth concerns, lead from paints and ceramic products, caulking, and pipe solder has been dramatically reduced in recent years. The use of lead as an additive to gasoline was banned in 1996 in the United States.
. 

### What happens to lead when it 

### enters the environment'! 

# o Lead itselfdoes not break down. but lead compounds are changed by sunlight, air, and water. 

# o When lead is released to the air, it may travel long distances before settling to the ground. 

# o Once lead falls onto $oil, it usually sticks to soil particles. 

# o Movement oflead from soil into groundwater will dcpend on the type of lead compound and the characteristics ofthe soil. 

### How might I be exposed to lead'? 

# o Eating food or drinking water that contains lead. Water pipes in some older homes may contain lead solder. Lead
. can leach out into the**w~l!er.** 

# o Spending time in areas where lead-based paints have been used and are dcteriorating. Deteriorating lead paint can contribute to lead dust. 

# o Working in ajob where lead is used or engaging in certain hobbies in which lead is used, such as making stained glass. 

# o Using health-care products or folk remedies that contain lead. 

### How can lead affect my health'! The effects oflead are the same whether it enters the body through breathing or swallowing. Lead can affect almost every organ and system in your body. The main target for lead toxicity is the nervous system, both in adults and children. Long-term exposure ofadults can result in decreased performance in· some tests that measure functions ofthe nervous system. It may also cause weakness in fingers, wrists, or ankles. Lead exposure also causes small increases in blood pressure, particularly in middle-aged and older people and can cause anemia. Exposure to high lead levels can severely damage the brain and kidneys in adults or children and ultimately cause death. In pregnant women, high levels ofexposure to lead.may cause miscarriage. Highlevel exposure in men can damage the organs responsible for sperm production. 

### How likely is lead to cause cancer? We have no conclusive proofthat lead causes cancer in humans. Kidney tumors have developed in rats and mice that had been given large doses ofsome kind oflead compounds.

(DHHS) has determined that lead and lead compounds are reasonably anticipated to be human carcinogens and the EPA has determined that lead is a probable human carcinogen. The International Agency for Research on Cancer (IARC) has determined that inorganic le:td is probably carcinogenic to humans and that there is insufficient information to determine whether organic lead compounds will cause cancer in humans.
. . 

## How can lead affect children? Small children can be exposed by eating lead-based paint chips, chewing on objects painted with lead-based paint, or swallowing house dust or soil that contains lead. Children arc more vulnerable to Icad poisoning than adults. A child who swallows large amounts oflead may develop blood anemia, severe stomachache, muscle weakness, and brain damage. Ifa child swallows smaller amounts oflead, much less severe effects on blood and brain function may occur. Even at much lower levels ofexposure, lead can affect a child's mental and physical growth
.. Exposure to

### I~ad is more dangerous for young and unborn children. Unborn children call be exposed to lead through their mothers. Hannful cffectS include premature births, smaller babies, decreased mental ability in the infant, learning difficulties, and reduced growth in young children. These effects are more common ifthe mother or baby was exposed to high levels oflead. Some ofthese effects may persist beyond childhood. 

## How can families reduce the risks ofexposure to lead? 

# o Avoid exposure to sources of lead. 

# o Do not allow children to chew or mouth surfaces that may have been painted with lead-based paint. 

# o Ifyou have a water lead problem, rUIl or flush water that has been standing overnight before drinking or cooking with it 

# o Some types ofpaints and pigments that are used as make-up or hair coloring contain lead. Keep these kinds of products away from children 

# o Ifyour home contains**lead-~ased** paint or you live in an area contaminated with lead, wash children's hands and faces often to remove lead dusts and soil, and regularly clean the house ofdust and tracked in soil. 

## Is there a medical test to determine whether I've been exposed to lead? A blood test is available to measure the amount oflead in your blood and to estimate the amount ofyour recent exposure to lead. Blood tests are commonly used to screen children for lead poisoning. Lead in teeth or bone? can be measured by X-ray techniques, but these methods are not widely available. Exposure to lead also can be evaluated by measuring erythrocyte protoporphyrin (EP) in blood samples. EP is a part ofred blood cells known to increase when the amount oflead in the blood is high. However, the EP level is not sensitive enough to identify children with elevated blood lead levels below about 25 micrograms perdeciliter**(~g/dL).** These tests usually require special analytical equipment that is not available in a doctor's office. However, your doctor
. can draw blood samples and send them 10 appropriate laboratories for analysis. \ 

## HasthefederalgovernmentmadeJ"ecommendations to protecthuman health? The Centers for Disease Control and Prevention (CDC) recommends that states test children at ages I and 2 years. Children should be tested at ages 

### 3-6 years ifthey have never been tested for lead, ifthey

### r~ceive services from public assistance programs for the poor such as Medicaid or the Supplemental Food Program for Women, Infants. and Children, ifthey live in a building or frequently visit a house buiIt before 

### 1950; ifthey visit a home (house or apartment) built before 

### 1978 that has been recently remodeled; and/or if they have a brother, sister, or playmate who has had lead poisoning. CDC considers a blood lead level of 

### 10 IlgfdL to' be a level ofconcern for children. EPA limits lead in drinking waterto 

### 15 J.lg per liter.
