ENGINEER: Macek \ BCS 

PV (kg/yr): 2,080 

Revision Notes / Assessment Overview: 

The FOCUS ready draft version of the IRER has been revised 

to incorporate: 

 - additional review of information provided by the 

 submitter in the submission 

- supplemental information provided on May 5, 2011 

(letter from Nichlolas Caparco of Lockheed Martin to 

Jim Alwood and Greg Macek of the USEPA) and| - information 

obtained through phone conversations between Nicholas 

Caparco and Greg Macek on May 4 and May 10, 2011 

Key changes to the previous version of the engineering report 

include: 

 1. Revision of the Assessed Lifecycle of the PMN chemical to 

include the following 2 stages: 

- Manufacturing and Processing at Lockheed Martin facility 

 - Incorporation into article at Lockheed Martin facility 

 Note: submitter indicated 100% site-limited use. 

 2. Use of submitter's monitoring data for lead exposures 

 as a basis for estimating inhalation exposure 

 3. Refinement of the media of release determinations for 

 the various release sources based on additional discussions 

 with the submitter. 

4. Assessment of the water release potential for the two 

lifecycle stages based on additional review and discussions 

with the submitter. 

5. Addition of information on PPE use 

6. Added results of wastewater monitoring data conducted by 

 the submitter. 

7. Added NPDES # for the POTW that receives wastewater from 

the Lockheed Martin facility. 

SUBMITTER: Lockheed Martin 

USE: Piezoelectric ceramics used for active and passive 

underwater acoustic systems. Consolidated Set: P- 70, 

 P-11-0271, P-11-0272, P-11-0273, and P-11-0274. 

OTHER USES: 

MSDS: Yes Label: No 

EPA SANITIZED Page 1 of 10
Gen Eqpt: Safety glasses are recommended for protection 

against exposures to dusts. Full body clothing should be 

worn to prevent potential exposure to skin. Sufficient 

mechanical ventilation (general and/or local exhaust) 

shall be provided to| maintain exposures below 

permissible air concentrations. Protective gloves 

required. 

Respirator: A NIOSH approved respirator with P100 filters 

shall be worn when airborne exposures may exceed 

OSHA/ACGIH permissible air concentrations. 

Health Effects: ACUTE: May produce eye, skin and 

respiratory tract irritation, effects on the nervous 

system and kidneys, gastrointestinal distress and anemia. 

Common symptoms are a loss of appetite, nausea, vomiting, 

stomach cramps, constipation, anxiety, difficulty in 

sleeping, fatigue, moodiness, headache, joint or muscle 

aches and decreased sexual drive. Extreme overexposure 

may lead to tremors, convulsions, paralysis, stupor, coma 

and death. // CHRONIC: Children have enhanced absorption 

and retention of ingested lead and are particularly 

sensitive to the chronic effects of lead, with slowed 

cognitive| development and reduced growth. May produce 

effects on the blood, nervous and| immune systems, blood 

pressure, kidneys as well as skin and pulmonary| 

inflammatory tissue masses, rickets-like bone deformities, 

 decreased sperm count| and spontaneous abortion. Common 

symptoms are a loss of appetite, metallic taste in the 

mouth, anxiety, constipation, nausea, pallor, fatigue, 

weakness, insomnia,| headache, nervous irritability, 

muscle and joint pain or soreness, fine tremors,| 

numbness, dizziness, hyperactivity and abdominal pain. 

Maternal overexposure| may produce low birth weight, 

birth defects and slowed postnatal neurobehavioral| 

development in the offspring. Extreme overexposure may 

lead to vomiting,| drowsiness, stupor, poor memory, 

restlessness, irritability, tremor, convulsions,| coma 

and death. Muscular weakness may develop and progress to 

paralysis| observed as "wrist-drop" and/or "foot-drop".

NOTES & KEY ASSUMPTIONS: 

Generated by the 06/07/2005 version of ChemSTEER. The PMN 

is manufactured domestically, therefore mfg, proc/use 

into piezoelectric ceramics are assessed. This PMN is 

part of a related set including P11-0270 through P11-0274. 

 All cases have the same manufacturing and proc/use and 

exhibit the same releases and exposures. Changes to the 

IRER may effect the assessment of the other 4 PMNs in the 

set. The PMN contains five elements of concern: lead, 

strontium, titanium, tungsten, and cobalt. The PMN PB 

rating is P3B2; therefore, a full assessment is required. 

Releases are assessed to all media. Note, submission 

specifies several dust releases to stack air, which is 

controlled by a bag house. Cleaning releases are 

collected in a collection sump pit. The submission 

implies this pit may discharge or be further treated. 

Solids collected in the bag house from air emissions or 

from collected sump pit solids are sent off-site as 

hazardous waste every 3-5 years. Therefore, releases 

presented in this IRER to air and water may occur 

regularly; whereas land and incineration releases are 

expected to collect over time and occur every 3-5 years.

ENVIRONMENTAL RELEASES ESTIMATE SUMMARY

may coincide with daily releases from the other sources 

to the same medium.

Output 2: 1.0E-2 kg/site-day over 13 days/yr from 1 site 

to: Onendaga County Department of Water and Environment 

Protection (NPDES # NY0002101) 

from: Water releases from cleanup activities including 

facility floors 

basis: User-Defined Loss Rate Model. Submission 

estimates release into POTW from the process of 0.01 

kg/bt from various cleanup activities. Submitter 

provided results of sampling of wastewater from the 

facility. Samples were collected on 1/13/11. Results: 

Lead - <0.02 mg/L; 0.0019 mg/L and zirconium - <0.010 

mg/L. 

Air 

Output 2: 1.1E-2 kg/site-day over 13 days/yr from 1 site

from: Air emissions from baghouse 

basis: User-Defined Loss Rate Model. Submission estimates 

0.6 kg/bt of dust emissions into baghouse filter 

(corresponds to a loss fraction of 0.4%, CEB dust model 

estimates 0.5% release from solids transfer activities. 

Submitter indicated that efficiency of the baghouse 

filter is 98.2%. Calculation: 0.6 x (1-0.982) = 0.011 

kg.

Inhalation: 

Submitter indicated that respirators (1/2 face respirator 

with P100 filter) are used whenever there is a potential 

for lead exposure by inhalation 

Exposure to Particulate (Class I) 

Output 2: 2.9E-1 mg/day over 13 days/yr 

Number of workers (all sites) with inhalation exposure: 

Basis: Various activities (weighing, mixing and transfer 

of powder and slurries); User-defined Inhalation Model. 

Submitter indicated in supplemental information that an 

industrial hygiene plan for the site is developed each 

January for the current year. Personal lead exposure is 

always included in the plan. The sampling plan involves 

analyzing personal lead exposure for each major process 

performed in the ceramic area. The plan is based on 

activity in the area. Recent sample results for the lead 

breakup process was 13 ug/m3. Recent average sample 

results for powder fabrication for 220 kg batch was 18 

ug/m3. OSHA Action level for lead is 30 ug/m3 and OSHA 

PEL for lead is 50 ug/m3. Although employees are not 

exposed above the action level for more than 30 days a 

EPA SANITIZED Page 6 of 10
year they still require lead levels to be measured every 

6 months. Recent blood lead levels for two employees in 

the area were less than 3 mcg/d. The other employee's 

blood level was 9 mcg/d. CEB estimate is based on 18 

ug/m3 (conservatively assumed to be an 8-hr TWA exposure). 

 Chemistry report estimated that PMN material is 60-66% 

lead oxide. Calculation: 18 ug/m3 (lead)/0.63 x 1.25 

m3/hr x 8 hr/day = 0.286 mg/day 

NOTE: The respirator class is: I. Particulate (including 

solid or liquid droplets).

Dermal: 

Submitter indicated that Tyvek suits and booties are 

required whenever an employee enters the ceramic area. 

Nitrile gloves are used when working with powders. There 

are several activities when the PMN may be handled in 

liquid form. The submission indicates that the same PPE 

requirements would be in place as for solids (tyvek suit 

and booties, Nitrile gloves).
