# I Intent To Test Notification General Notes on Chromium Sampling and Analysis The field emission sampling procedures used by Envisage Environmental, Incorporated, are presented in USEPA Reference Method 306, Determination of Chromium Emissions From Decorative and Hard Chromium Electroplating and Anodizing Operations. The chromium sampling train assembly may be found in the sampling train diagram. A brief description of its operation is presented below. Gas flow measurements will be conducted simultaneously with the chromium sampling so isokinetic rates can be maintained. The pitot system is zeroed and each leg is leak checked at greater than 3" H2

### 0 gage pressure for at least fifteen seconds. The average velocity pressure and temperature between the two runs will be used to calculate a chromium emission rate. The entire sampling train is vacuum leak checked from the nozzle opening at about (-)15" Hg gage pressure. The sample probe is positioned at the first sample point within the stack and sampling begins when the source reaches stability. Post-test run leak checks are performed as above with the sample train leak check conducted at the highest vacuum attained during the run and is held for one minute. Also incorporated into the field sampling and data analysis are those considerations and calculations contained in the following: 1) Construction Details of Isokinetic Source Sampling Equipment, US EPA Doc. APTD - 0581, April 1971. 2) Maintenance, Calibration, and Operations of Iso kinetic Source Sampling Equipment, US EPA Doc. APTD - 0576, March 1972. 3) "A Method of Interpreting Stack Sampling Data," by W.S. Smith et ai, June 14 - 19,1970. Laboratory analyse,s-which are followed by Envisage Environmental are those procedures stated in USEPA Reference Methocf.30SA, Determination of Chromium Emissions From Decorative and Hard Chromium Electroplating and ,'Anodizing Operations, with associated calculations presented therein. Envisage Environmental Inc. ,illso uses the on-site sampling procedures and sample analysis quality control and quality assurance requirements as published in USEPA Document SOO/4-77/027b June 1987, Volume

### ----------------------------------------------------------------------------------Intent To Test Notification Chromium F. Sampling Train Information Please refer to Sampling Train Diagram for schematic of proposed chromium sampling train. (Attachments No. 1) Sampling for chromium emissions will be performed using the USEPA Method S sample train (excluding filter) in place of the Mason Jar method. The sampling train is assembled as follows: Method 5 probe and impingers. The four impingers contain in order - 100 ml. of 0.1 N NaOH, 100 ml. of 0.1 N NaOH, empty, and 200 g. of silica

, gel. Glass probe liners will be used. The probe will be modified by installing a calibrated ''type K" thermocouple

for probe exit temperature measurement. This modification will not alter the heater construction design as specified in APTD-OS81. The on-site sample recovery is carried out as follows: After the post test sample train leak checks have been performed, the probe assembly is disconnected from the sample train and rinsed and recovered with the absorbing solution. The probe is considered clean and may be reused for the next sampling run. After the leak check operations the impingers are removed from the sample train. wiped clean from sealing grease, and stored in their labeled and recorded sample case.

### G. Laboratory Analysis

The protocol used for the laboratory analysis of the collected samples is as presented in USEPA Reference Method 306. The impinger liquid catch is measured volumetrically. The liquid contents are combined. The I 

### solutions are combined with the probe rinse and sent to an independent laboratory for analysis by Method 306.

### Envisage Environmental Incorporated conducted emission sampling at the Diamond Hard Chrome facility. Cleveland, Ohio on April 21, 1998. The objective of the test program was to measure the mass emission rates of total chrome emitted into the atmosphere from the 

### # 2 Chrome Scrubber exhaust. Emission sampling was conducted in triplicate with each of the test runs conducted over a one hundred and twenty-five (125) minute period.
Mr. Robert Tankovich, Diamond Hard Chrome, coordinated the test program and operational procedures. The Envisage testing team consisted of Messrs. Tyson Houchin and Matthew Wahrer.
The Cleveland Department of Air Pollution Control was represented by Mr. James Krause and Ms. Jane Bell. They were present throughout the testing period.

SAMPLING AND ANALYTICAL PROCEDURES The sample collection and analysis techniques utilized for this test program were performed in accordance with the following USEPA Reference test methods: USEPA Method 1 USEPA Method 2 USEPA Method 3 USEPA Method 4 USEPA Method 306
METHODS 1 Sample and Velocity Traverses for Stationary Sources. Determination of Stack Gas Velocity and Volumetric Flow Rate. Gas Analysis for Carbon Dioxide, Oxygen, Excess Air, and Dry Molecular Weight. Determination of Moisture Content in Stack Gases. Determination of Chromium Emissions from Decorative and Hard Chromium Electroplating Operations and Anodizing Operations.

The exhaust stack serving the #2 Chrome Scrubber is rectangular and had internal dimensions of 28 x 21 inches. The stack had an upstream distance of 48" (2.09 equivalent diameters) and a downstream distance of 23" (1.0 equivalent diameter). Sampling was conducted through five (5) sample ports with a total of twenty-five sampling pOints used, five (5) sampling points per port. METHOD 2 Three (3) foot ·S" type pitot tubes, and a Type K thermocouples were used for measuring the gas stream's velocity and temperature. The pressure drop, temperature and sample were taken and measured by traversing across the internal dimensions of the exhaust through the sample ports. METHOD 

### 3 Sampling for the determination of dry gas molecular weight was performed utilizing USEPA Method 3 procedures.

Integrated samples were extracted from the stack during the sample runs. The sampling system**con~isted** of a stainless steel probe, followed by a Teflon sample line attached to a polyethylene squeeze pump. The squeeze pump was coupled with a leak free Tedlar bag. The concentration of oxygen and carbon dioxide in the sample was determined by using a Bacharach "Fyrite" Portable Gas Analyzer. Fyrite analysis provides for the selective absorption of oxygen in Burell Oxysorbent and carbon dioxide in potassium hydroxide solutions. The difference in gas volume before and after the absorption represents the amount of constituent gas in the Sample. Each sample was analyzed three (3) times, and the average of the readings for each run were used in calculating the emission rate.

### 6 METHOD 

### 4 The moisture content of the gas stream was determined by USEPA Method 4, impinger procedure. The impinger procedure consists of an integrated gas stream sample which is drawn through a series of chilled impingers and tarred dry silica gel, by means of calibrated dry gas meter. The net weight of liquid and liquid absorbed by the silica gel were recorded for the calculation of moisture content per sample volume. METHOD 306 

### The chromium emissions exiting the exhaust stack were measured by following the procedures outlined in USEPA Method 306. The sampling train consisted of a glass nozzle connected to a heated Pyrex liner. The liner was connected to a series of impingers (Method 4) which contained; 100ml of sodium hydroxide in the first two, followed by an empty, and the final impinger containing the 200 grams of dry silica gel. Samples were taken from the gas stream isokinetically through the nozzle and sample train. Exit gas temperature of the impingers was maintained below 68°F. with an ice bath. At the conclusion of each test run the sample train was allowed to cool and a leak check of the train and pitot tube was performed. After the leak check the probe and nozzle cleaning was performed in the field using a nylon bristled brush and a carrier liquid of sodium hydroxide. The field cleaning of the sampling probe and nozzle follows this procedure; At the conclusion of the test run the nozzle is removed, the inside surface is rinsed. brushed. and rinsed until visually clean of particulate matter. The rinse is collected in a glass sample bottle and capped with a teflon lined lid. The sample probe is rinsed into the same container by tilting the probe assembly and rotating so that the rinse liquid empties into the collection bottle. The nylon bristled brush is then introduced into the liner. By using a forward and rotating action the liner is brushed clean with copious amounts of sodium hydroxide. Visual inspection is then made and the process repeated until the rinse liquid is visually clean. A final rinse is then rotated down the inclined probe liner. The cleaning brushes are then rinsed and the sample bottle capped and secured in the appropriate test run container.
The rinse samples including the impinger liquid are taken and analyzed in the laboratory. The impinger liquid is measured volumetrically and transferred to a storage bottle. The liquid is then transported to an independent laboratory for analysis of chromium. 

## GENERAL
All analytical procedures were performed in accordance with the methods speCified in the Code of Federal Regulations, Title 

### 40, Part 60, Volume 43. Example calculations to determine the emission rates can be found in the example calculation section of this report.
