CERCLA Incident Category: Time-Critical Removal Action

1.1.2	Site Description

1.1.2.1	Location

The Site is located in and around the city of lola, Allen County, Kansas. The main area of the former United Zinc property is
located on the east side of lola within a mixture of residential and commercial properties. The facility was one of several zinc
and lead smelting operations in the area between 1902 and 1925. Residential and non-residential properties were
contaminated with elevated levels of lead.

1.1.2.2	Description of Threat

FUZ_polrep_32.htm[6/22/2016 7:39:52 AM]


-------
Lead, a hazardous substance as defined by Section 101(14) of the Comprehensive Environmental Response, Compensation,
and Liability Act (CERCLA), as amended, has been released into the soil at the Site. The primary contaminants of concern at
this Site are lead and lead compounds.

1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results

Refer to PolRep #1.

2. Current Activities
2.1 Operations Section

2.1.1	Narrative

The removal action consists of excavation and proper disposal of soil and/or waste containing lead concentrations greater
than 400 milligrams per kilogram (mg/kg) from properties meeting the following criteria: residential properties where
a composite sample exceeds a concentration of 800 mg/kg; high child impact areas such as schools and daycare facilities
where a composite sample exceeds a concentration of 400 mg/kg; and residential properties where a child with a blood lead
level of 10 micrograms per deciliter (|jg/dl) or greater resides and soil contains lead concentrations over 400 mg/kg. Currently,
approximately 350 properties have been identified that meet these criteria. Excavated soil is transported to the Allen County
Landfill, a RCRA Subtitle D landfill, and used as daily cover.

2.1.2	Response Actions to Date.

Excavation was completed at the following properties during this reporting period:

A full list of properties (currently 110) addressed during this action is presented in the Notices section of this website.

The EPA continued efforts to assess properties which were not previously sampled. The EPA completed an initial
reconnaissance of these 890 unsampled properties and determined that approximately 350 properties are residential. To
date, access has been obtained for 220 of these properties (of which 214 have been sampled). Access has been declined for
59 properties.

2.1.3	Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)

The PRP search is ongoing. No PRP has been identified to date.

-------
2.2.1	Anticipated Activities

2.2.1.1	Planned Response Activities

Excavation and backfilling operations will continue. Because of the onset of higher temperatures, sod will be installed at a
reduced rate until fall to allow crews to maintain a higher frequency of watering. To minimize the number of properties left
without cover, larger properties will be targeted, which will reduce the number of properties completed each week.

START contractors will continue to process samples that have been collected for the assessment task. See Section 2.1.2 for
additional information regarding these properties.

2.2.1.2	Next Steps

The Site was listed on the National Priorities List (NPL) on May 21, 2013. A remedial action is being planned.

2.2.2	Issues

No issues at this time.

2.3	Logistics Section

Not applicable. The Logistics Section is not activated due to the size of the removal action.

2.4	Finance Section

6.	Additional sources of information

6.1 Internet location of additional information/report

Lead is classified by the EPA as a probable human carcinogen and is a cumulative toxicant. The early effects of lead poisoning
are nonspecific and difficult to distinguish from the symptoms of minor seasonal illnesses. Lead poisoning causes decreased
physical fitness, fatigue, sleep disturbance, headache, aching bones and muscles, digestive symptoms (particularly
constipation), abdominal cramping, nausea, vomiting, and decreased appetite. With increased exposure, symptoms
include anemia, pallor, a "lead line" on the gums, and decreased handgrip strength.

Children are more vulnerable to lead poisoning than adults. For children, lead can damage the central nervous system, kidneys
and reproductive system. At higher levels, it can cause coma, convulsions and death. Even low levels of lead are harmful and
are associated with decreased intelligence, impaired neurobehavioral development, decreased stature and growth, impaired
hearing acuity, and possibly high blood pressure.
