**Trends in Chromium and Lead Concentrations in Petroleum Refinery
Waste**

**[Regulatory Developments]{.underline}**

On September 8, 1994, EPA issued a final MACT rule that eliminated the
use of chromium-based water treatment chemicals and subsequently
chromium compound emissions from IPCTs.

On October 18, 2005, EPA proposed no changes to a rule that governs
emissions of toxic air pollutants from IPCTs.

(EPA required to assess the residual risk remaining after the
implementation of the 1994 standards.)

1992]{.underline}

*"A comparison of F037 and F038 characterization data with those for
K051 and K048 indicates that many of the constituents identified in K051
and K048 are also present at similar concentration in F037 and F038.
Based on the similarities of industry, processing stages, and waste
characterization data between F037,F038,K048 and K051, the Agency
believes that F037 and F038 can be treated to similar concentrations
using identical technologies as those identified for K048 and K051. EPA
is therefore placing F037 and F038 into the same waste treatability
group as K048-K052*."

**Sample Calculations**

**Sample Calculation (Lead):**

(20 MT)(1000kg/MT) = 20,000 kg waste

(20,000 kg waste)(1760 mg/kg) =35,200,000 mg Leady

In 20 MTD gasifiers 20% mass goes to syngas; 80% to bottoms with 100% of
metals

Therefore; 16 MTD of bottoms generated.

18,800,000 mg Lead/(16 MT)(1000kg/MT) = 2200 [mg/kg of Lead]{.underline}

Apply 20:1 TCLP ratio (multiply by 0.05) = [110 mg/L TCLP;]{.underline}
Apply 1000:1 (multiply by 0.001) = [2.2 mg/L TCLP]{.underline}

**Sample Calculation -- Method 1:**

(1800 MT of petcoke)(3.53/10E6) + (200 MT of secondary material)
(0.05/10E6) = 0.006354 + .00000005 = .00635405/200tons x 10E6 = 31.77 =
[31.8 mg/kg Arsenic in bottoms]{.underline}

Application of 20:1 ratio from TCLP (multiply by 0.05): 31.77 x .05 =
31.8 x 0.05 = [1.59 mg/L TCLP]{.underline}

Application of 1000:1 ratio from TCLP (multiply by 0.001): 31.77 x .001
= 31.8 x 0.001 = [0.0318 mg/L TCLP]{.underline}

**Sample Calculation -- Method 2**

(1800 MT of petroleum coke)(1000kg/MT) = 1.8 x 10E6 kg petroleum coke
(200 MT of secondary material)(1000kg/MT) = 2.0 x 10E5 kg secondary
material.

(1.8 x 10E6 kg petroleum coke)(3.53 mg Arsenic in petroleum coke/kg) =
6.3 54x 10E6 mg Arsenic

(2.0 x 10E5 kg secondary material)(0.05 mg Arsenic/kg secondary
material) = 1 x 10E4 mg Arsenic

6.354 x 10E6 mg Arsenic +.01 x 10 E6 mg Arsenic = 6.364 x 10E6 mg
Arsenic

200 MT of gasifier bottoms

6.364 x 10E6/(200MT)(1000 kg/MT) = [31.8 mg/kg Arsenic in
bottoms]{.underline}.

Application of 20:1 ratio from TCLP (multiply by 0.05): 31.8 x .05 =
[1.59 mg/L TCLP]{.underline}

Application of 1000:1 ratio from TCLP (multiply by 0.001): 31.8 x 0.001
= [0.0318 mg/L TCLP]{.underline}

## Sample Calculation -- Method 1 (Arsenic):

2000 MT (3.53/10E6) = 0.00706 MT of Arsenic

0.00706 MT of Arsenic/200 MT of bottoms = 0.0000353 x 10E6 = [35.3 mg/kg
Arsenic in bottoms]{.underline}

(35.3)(.05) = [1.76 mg/L TCLP]{.underline}

(35.3)(.001) = [0.0353 mg/L TCLP]{.underline}

**Sample Calculation -- Method 2 (Arsenic):**

(2000 MT)(1000 kg/MT) = 2,000,000 kg of petroleum coke

(2,000,000 kg)(3.53mg Arsenic/kg) = 7,060,000 mg Arsenic

7,060,000 mg Arsenic/(200 MT)(1000kg/MT) = [35.3 mg/kg Arsenic in
gasifier bottoms]{.underline}

(35.3)(.05) = [1.76 mg/L TCLP]{.underline}

(35.3)(.001) = [0.0353 mg/L TCLP]{.underline}
