From: Jones, Jennifer Sent: Thursday, July 21, 2011 10:28 AM To: hrichardsonpa(@emargmail.com Cc: Jones, Jennifer; Bennett, Bradley; Hodge, Al- Dumpor, Samir Subject: RE: Blank Renewal Form for NCG1400369.doc Mr. Richardson, I checked our files this morning to make sure that we didn't already have the correct information on file. It turns out we did have an application for an NPDES permit, as applied for by °Manifred D. Alligood" — apparently when it was entered into the database here it was done incorrectly. I should have checked that yesterday before calling — it was a long day and I didn't think to do that yesterday. I have called Mr. Alligood and told him that we do have the correct application and name for NCG140000, and he does not need to do anything further for the NPDES ready -mixed concrete permit. However, I did notice that Mr. Alligood olso hos a state storm water permit issued to ABHW Concrete (SW7061128). As that was issued out of the Washington Regional Office, I can't see the actual application, but you and Mr. Alligood will want to make sure that the applicant was "Manifred D. Alligood" for that permit as well — as the name "ABHW Concrete" does not appear in the NC Secretary of State's database for registered companies in NC. Again, I apologize for any inconvenience on your or Mr. Alligood's part. If you can please forward this to him for his records I would appreciate it. I have copied my supervisor and the supervisor of the Washington Regional Office. Thank you, sensitivty of the mean diameter, which is 0.00008. Therefore, the value of the mean sediment diameter used to determine the bed load rate is virtually immaterial. The Shiel equation is shown to be very sensitive to the slope and about half as sensitive to the hydraulic radius, mean diameter, and flow rate, which each have a magnitude of the relative sensitivity of approximately 1.0. The SchoklitSCh equation is very sensitive to the slope and hydraulic radius and very insensitive to the mean diameter. The relative sensitivities of the inputs are identical to those of the DuBois equation. It is interesting to note that the Goncharov equation is one of the two equations, the other being the Shamov equation, that produce a positive value for the relative sensitivity of the mean diameter, meaning that as the mean diameter of the sediment increases the bed load decreases. All other equations show a negative value for this input parameter, which means that as the mean diameter of the sediment increases the bed load decreases. The negative sensitivities suggest that, since an increase in sediment diameter means larger sediment particles and thus heavier particles, then the rate of bed -load transport would decrease since heavier particles are more difficult to move. However, the positive sensitivities suggest that as the particles increase in size they become heavier, so that although fewer particles are moved, the total rate of bed load transport increases due to the heavier weight of each particle. The Goncharov equation is also extremely sensitive to the mean velocity and critical velocity as shown by relative sensitivity values of 5.0 and -4.0, respectively. The Shamov equation is fairly sensitive to the mean sediment diameter (a positive value as discussed earlier) and extremely sensitive to the mean velocity and critical velocity as in the Goncharov equation.

Stormwater Permitting Unit 1617 Maif Service Center, Raleigh, NC 27699-1617 512 N. Salisbury St, Raleigh, NC 27604 x and Goncharov equations are somewhat sensitive to the depth of flow. It can be concluded by the negative relative sensitivity values that as the depth of flow increases, the bed load rate decreases. This is supported by the fact ,that as the depth of flow increases, the flow cross -sectional area normal to the direction of flow increases. Therefore, assuming a constant flow rate and using the continuity equation, the mean velocity must decrease, thus decreasing the amount of bed load capable of being transported. The Egiazarov equation is sensitive to the slope and flow rate. It is about 1.4 times more sensitive to the mean diameter and maximum dirameter of sediment particles. The Meyer -Peter equation is shown to be quite sensitive to the slope and Slightly less sensitive to the flow rate. However, it is very insensitive to the mean sediment diameter. Comparison of Relative Sensitivities of Variables As stated previously, by analyzing the rows of Table 3, the relative sensitivities can be used to show which equations are the most or least sensitive to particular input parameter. For example, it is apparent that the DuBois, the Shields, and the Schoklitsch equations are all extremely sensitive to slope, while the Egizarov and the Meyer -Peter equations are less sensitive; also, the Goncharov and the Shamov equations do not require it as an input. The hydraulic radius is seen to be important in the DuBois and Schoklitscn equations and less important than in the Shield equation. The DuBois, the Schoklitsch, and the Meyer -Peter equations are virtually insensitive to the mean sediment aiameter, while the Shields and the Egiazarov equations are sensitive to it.

The only equation that requires the maximum diameter of sediment particles is the Egiazarov equation. The depth of flow is a necessary input only for the Goncharov and the Shamov equations, both of which have moderate relative sensitivity values. The flow rate is required for the Shield, the Egiazarov, and the the Meyer -Peter equations, with a nearly constant relative sensitivity of about 1.0. Finally, the mean velocity and critical velocity are required inputs for the Goncharov and the Shamov equations only and have extreme effects on the bed load as seen by the large relative sensitivities of approximately 4.7 and -3.7, respectively.

High strength wastewaters include drum rinse out (and truck rinse off commingled with it plus incident rainfall) at the recycle system chambers. i. High pH and TSS wastes settle in three chambers and a recycle pit. ii. Overflow from the pit enters an infiltration basin (infiltrative capacity substantiated by Engineer's talcs) sized to take the 25-yr, 24-hr storm plus one day of drum rinse flows, plus one foot of freeboard. iii. Overflow from the infiltration basin and/or high -high overflow from recycle pit will flow to wet detention basin before discharge to receiving water. iv. Conclusion - High strength waters and stormwaters commingled with them meet the requirement for a 25-yr, 24-hr hold without discharge. Recovery of the design capacity is provided by the infiltration basin infiltrative losses. OK. b. Low strength, low volume wastewaters include aggregate irrigation and loading area washdown. i. Engineer provides talcs to show that the site soils are sufficiently porous that the estimated quantities of irrigation water and washdown water will not be discharged off site under dry conditions. ii. Engineer concludes that under wet conditions the commingled wastewater and stormwaters will flow to the wet pond. Engineer fails to make the specific argument that the discharge will meet TSS, pH, and settleable solids limits in the permit. But, given the very large dilutive affect from the commingling of the low strength wastes with the site stormwater, it is reasonable to conclude that the wet pond discharge will meet permit limits. OK. iii. Special provisions - Permit transmittal letter to note that the discharge from the wet pond is to be treated as the wastewater discharge sampling point. Engineer and applicant may not be aware that the potential for commingling of all site stormwater with any amount of wastewater requires that what would otherwise be viewed as just stormwater must be treated as the wastewater discharge. 3. Conclusion - ok to permit under NCG14. Add emphasis in xsmittal letter on sampling of wastewater. 4. Note - The site circumstances are fairly unusual. The high strength wastes receive settling in a recycle system, infiltration sized for the 25-yr storm, and overflow treated in a wet pond. This system would be permittable for the high strength wastes without the wet detention pond. The extra treatment provided in the wet pond is not often provided in other designs.

Director Division of Water Quality December 4, 2006 Mr. Manfred D. Alligood, Jr. 1935 West Fifth Street Washington, North Carolina 27889 Subject: Return of NCG140000 NOI #1135 ABHW Concrete, new Washington plant Beaufort County Dear Mr. Alligood: On December 1, 2006, the Division of Water Quality, Stormwater Permitting Unit received your Notice of Intent (NOI) to be covered under North Carolina's general permit NCG140000, submitted for your new location in Washington. Your submittal contained a check for $80, one NOI form, one set of calculations, one copy of two site location maps, an Erosion and Sedimentation Control Plan Permit Application, and three copies of a site plan by Hood Richardson, P.A. The submittal is significantly deficient, and we are returning it unprocessed. The submittal is deficient in the following particulars. 1. Inadequate design basis. You have applied for a permit to discharge stormwater and wastewater under our general permit NCG140000, and for an Authorization to Construct treatment facilities. North Carolina rules require DWQ to conduct an engineering review of your application. Briefly, our key design basis criteria for review for your proposed new construction are: Does the application include engineering calculations that predict compliance with the permit li.mits (i.e. TSS removal talcs, Settleable Solids removal talcs, pH correction narrative) for wastewater discharges; or else, does the application include water balance calculations that show that there will be no discharge of wastewaters from the recycle system in response to the 25-year, 24-hour storm event? The two criteria are stated in items 14 and 15 of the NOI that you submitted with the package. The submittal is not approvable in that it is not based on either of the two approvable design bases. The submitted calcs seem to be based on a design approach that may be acceptable under other jurisdictions and under other programs (the coastal State Stormwater Management program, for instance), but such a design approach is not acceptable for the federal NPDES stormwater discharge permit that you have applied for. Note also that there is no design narrative that tells us specifically how the stormwater and wastewater flows will be generated, collected, conveyed, treated, and discharged. Further, note that the -submittal makes no attempt to address the control of high -pH wastewaters presumably to be discharged from the operations of your proposed ready mixed concrete facility. 2. Inadequate site plan and engineering details. Please consider that as reviewers, we can't tell from the site plan whether the measures you are proposing are sufficient, or not, because the drawing does not present a complete picture of the site with respect to our NorthCarolina North Carolina Division of Water Quality 1617 ]Mail Service Center Raleigh, NC 27699-1617 Phone (919) 733-7058 Customer Service Internet: www.ncwaterquah1y.oM Location: 512 N.

Specifically: we must know where the wastewater and stormwater discharge points are - - they're not labeled as such on the site plan. We must know where all the wastewater flows originate - - for most ready mix sites we need to see the truck rinse off station and the overflow piping from the recycle system (neither identified on the site plan), in addition to the drum wash out station, the recycle system, the aggregate piles, and the batch plant (all shown.) We must see the proposed finished grade topo lines so that we can confirm for ourselves the direction of overland flow at the constructed facility. We must see a delineation of the contributing drainage areas that will flow to the proposed wastewater and stormwater control measures.. Further, we must see engineering details of the configuration of the mixing drum wash pit in order to review the volume and hydraulic operation of that structure.

Alligood, Jr. Dear Mr. Alligood: This office has completed its review of the erosion and sedimentation control plan for the referenced 3.9 acre disturbance. Based on the information provided, we have determined the submitted plan for the grading associaied with the construction of a commercial facility, if properly implemented and responsibly maintained, should meet the intent and minimum requirements of the Act. We, therefore, issue this LETTER OF APPROVAL. In 1973, the Sedimentation Pollution Control Act (copy available upon request) was enacted. It established a performance oriented program with the OBJECTIVE of PREVENTING SEDIMENT DAMAGE to adjoining properties and/or natural resources resulting from land disturbing activities through the use of reasonable and appropriate Best Land Management Practices, based on the approved plan and changing site conditions, during the course of the project. AS THE DECLARED RESPONSIBLE PARTY, YOUR LEGAL RESPONSIBULITY is to understand the Act and comply with the following minimum requirements of the Act and the above listed modifications (if any): -- an erosion and sedimentation control plan is only valid for 3 years following the date of initial approval, if no land -disturbing activity has been undertaken; 943 Washington Square Mall, Washington, North Carolina 27889 Telephone 252-546-6481, FAX 252-975.3716 Mr. Manfred D.

The mulch must cover at least 75 % of the seeded area after it is either tacked, with an acceptable tacking material, or crimped in place; -- in order to comply with the intent of the Ae7, the scheduling of the land - disturbing activities is to be such that both the area of exposure and the time between the land disturbance and the providing of a ground cover is minimized; -- . Mr. Manfred D. Alligood, Jr. December 22, 2006 Page 3 -- a permanent ground cover. sufficient restrain erosion, must be.provided within the shorter of 15 working or 90 calendar days after completion of construction or development on any portion of the tract (RYE GRASS I� NOT in the APPRUY seeding specifications SM is it an ACCEPTABLE substitute for the providing of a nurse cover for the permanent grass cover); and, -- this approval is based, in part, on the accuracy of the information provided in the Financial ResponsibiiitylOwnership form submitted with the project plans. You are required to file an amended form if there is any change in the information included on the form. This approval and the financial responsibility/liability cited in it does not automatically transfer with a change in project ownership. Be advised that to ensure compliance with the approved plan and the program requirements, unannounced periodic inspections will be made. If it is determined that the implemented plan is inadequate, this office may require the installation of additional measures and/or that the plan be revised to comply with state law. (Note: Revisions to the scope of this project without prior approval of the plan showing the changes can be considered a violation). Failure to comply with any part of the approved plan or with any requirements of this program could result in the taking of appropriate legal action (civil or criminal) against the financially responsible party (Manfred D. Alligood, Jr.). Some options are Stop Work Orders and the assessing of a civil penalty of up to $5000 for the initial violation plus up to $5000 per day for each day the site is out of compliance. In recognizing the desirability of early coordination of sedimentation control, we believe it would be beneficial for you and your contractor to arrange a preconstruction conference to discuss the requirements of the approved erosion and sedimentation control plan. Prior to beginning this project, YOU ARE REQUIRED TO either CONTACT THIS OFFICE TO ADVISE Mr. Gary Novak (252-946-6481, ext. 3857) OF THE CONSTRUCTION START-UP DATE, contractor and on -site contact person OR complete and return the attached Project Information Sheet to the above named. Acceptance and approval of this plan is conditioned upon your compliance with Federal and State water quality laws, regulations and rules. In addition, the land disturbing activity described in this plan may also require approval or permitting from other agencies - Federal, State or local. These could include the U.S. Army Corps of Engineers under Article 4.0.4. jurisdiction, the Division of Water Quality - Surface Water Section under stormwater regulations (contact the Stormwater group at 252-946-6481), county, city or town agencies under other local ordinances, or other approvals that may be required. This apprQyal does nQJ 5upernde any other apprQv l or permit. Mr. Manfred D. Alligood, Jr. December 22, 2006 Page 4 Please be advised that a rule to protect and maintain existing buffers along watercourses in the Tar -Pamlico River Basin became effective on January 1, 2000. The Tar -Pamlico River Riparian Area Protection and Maintenance Rule (15A NCAC 2B.0259) applies to a 50 (horizontal) foot wide zone along all perennial and intermittent streams, lakes, ponds and estuaries in the Tar - Pamlico River basin with forest vegetation on the adjacent land or "riparian area". in riparian areas, the rule prohibits all land disturbance, new development and fertilizer use in the first 30 (horizontal) feet directly adjacent to the stream and/or coastal wetland vegetation. With the exception of clearing, seeding and a one-time fertilizer use to establish the grass, the rule prohibits new development in the zone 20 feet landward of the first 30 feet of riparian area. For more information about the riparian area rule, please contact the Division of Water Quality's Wetland/401 Unit at 919-733-1786. Please be advised that all land -disturbing activities affecting 1 or more acres are required to have a (Federal) NPDES permit. Enclosed is the Construction Activities General NPDES Permit - NCGOlOOOO for this project. The responsibility for understanding and complying with this permit rests with you, the financially responsible party. Be aware that failure to comply with this permit could result in both the State and Federal governments taking appropriate legal action. Contact the Division of Water Quality - Surface Water Section at (252) 946-6481 should you have any questions regarding monitoring and record keeping requirements of the permit.

An infiltration pond sufficient to contain this storm for lie truck wash pad, the settling basin and one day of mixing drum wash water is provided. The pond is sized so that the entire above described volume mill infiltrate into the ground leaving the pond empty within 24 hours.

All surface water from operations and roads is either sheet flowed or collected by swales and directed to the stonnivaler pond. Stonnwater is collected and bled off by orifice over a period of two days. WASTEWATER On site sewage will be treated in a on site in a ground absorption system- permitted by the Bcauforl County Health Department. Wastewater from operations is generated during the wash out of truck mixing drums. This estimated to be 6,000 gallons per day. Treatment of this water passes thru a three celled settling basin arranged so that over flow from either process or storm water from die area will be disposed of in a separate absorption pond. All other stortr►vater is treated in a separate stonnivater pond. WASTEWATER BALANCE This facility will be permitted to produce 90,000 cubic gallons of concrete per year or 360 cubic yards per single slift day on a 5 day per week operation. One hundred sixty seven pounds (20 gallons) of water are required to make one cubic yard of concrete. Therefore. 7,200 gallons of water are required for one dan of production. 'l'ltis is a short fall of 1,200 gallons. There will be no ovei-11mv to the wastewater absorption pond during a normal day of operation. The three chambered settling basin is a triangular shaped cross section- is 22.8 feet long at the 4.5 feet deep. This is 10,406 gallons of storage. The settling basin is capable of holding (I O,406/6,000) 1.73 days of operation. Water will be recycled to the concrete miring by a ptunp installed in I1►c clean end -settling basin. t Recoven, of water in the settling basin is accomplished by use of one -inch diameter (leveling) siplions. DENR - WATER CAAM Wetlands & SWmwmW Brandt -2- WASTE WATER AND THE 25 YEAR 2 4 HOUR STORM, Tlie 25 year 24 hour stone event is 8 inches of rainfall. An in -filtration pond stiff icieut to contain this storm for the truck wash pad, the settling basin and one day of mixing drimi awash water is provided. The bond is sized so that the entire above described volume will infiltrate into the ground leaving the pond empty within 24 hours. Tlierefore, there is no run off from the waste water treatment pond until the 24-hour storm has been exceeded. An hourly water balance of the infiltration rate would show that more than an 8-inch 24 hour rain is required to overflow the emergency spillway. The overflow runs over the 29 foot long concrete lip of the settling basin and then into the slonnwater treatment pond. SUSPENDED SOLIDS Suspended solids from wastewater will leave the property only during rainfall events that are more intensive than the 25 year storm. By the time of overflow from slonns of greater intensity than the 25 year storm, solids will have either settled in the settling basin or have been flushed into the absorption pond. An 8-inch 24-hour rain is sufficient to have cleaned all land surfaces of'suspended solids. fit addition the rousing of the wastewater storm thru. the stonnwater pond provides back-up treatment. Suspended solids from die wastewater stream will not leave this property during normal operations and are unlikely to be exit lie property in concentration sufficient to violate the standards during stone events more intense than the 25-year storn, because of the granular nature of soils and materials used to produce concrete. PH CONTROL Concrete .wash water normally has a high pH. There will be no water ]caving die property or being infiltrated into the ground during normal operations. As has been shown fresh make-up water will be needed on a daily basis. The dilutive effect from rain storms of any residual process water washed into the absorption pond. the small volume of available process water, and the low number of overflow events will not have a measurable impact on ground water. 4�` '� t' 'therefore, pH control should not be required at this site.ZZe yJ�Jdp2 F5i?ln ii F�1*�4 Z� 1 F- Vi U.

Director Division of Water Quality March 12, 2007 Mr. Manfred D. Alligood, Jr. 1935 West Fifth Street Washington, North Carolina 27889 Subject: Additional Information Request Stormwater application NCG140369 ABHW Concrete, Washington Beaufort County Dear Mr. Alligood: On January 4, 2007, the Division of Water Quality, Stormwater Permitting Unit received your second application for coverage under General Permit NCG140000, authorizing the discharge of process wastewater and stormwater from your proposed facility in Washington. North Carolina rules require DWQ to conduct an engineering review of your permit application, Some portions of the submittal were unclear to us and on March 7, 2007, we contacted your engineer, Hood Richardson PA, for clarification. We are requesting a written response in order to continue processing your application. Please submit additional information addressing the items listed below. 1. Site Plan and design details. a..' I'm unclear on the purpose of the portable siphons between the cells of the wash pit, and have some concern that they may re -suspend solids that have already settled in the cells. Please explain their purpose or revise the design details showing the siphons. b: It is not clear that the wash pit structure features the 1' freeboard required in item 15 of the permit application (Notice of Intent form). Please reconcile by either f explanation or by revising the wash pit detail elevations. •c. Please revise the truck wash pad drawings to add curbing along two sides of the truck wash pad in order to ensure that all wash down flows will be directed into the wash pit. d. It appears that the wash pit is designed to overflow at elevation 15.0'. Specifically, three of the four cells have a ramped bottom that has a design, elevation of 15.0' at the lip so that the cells would fill up and overflow out the front of the cells, which I believe is the design intent. However, the top of wall for the whole structure is identified also as elevation 15.0', meaning that the overflow would not be controlled at the lip of the ramp into each cell, but would also overflow from the entire structure. Please revise the design details to control overflow from just the front of. the cells. 2. Design basis and design narrative. a. The design narrative does not address three additional wastewaters that ready - mixed concrete facilities typically generate: wash down waters from the truck loading.' area, drainage from irrigation of the materials stockpiles, and truck rinse off flows. We understand from discussions with Mr. Richardson that the truck rinse off will take place on the truck wash pad, along with the drum rinse out, which is acceptable. However, the two other wastewater.f lows are not addressed.; in the design narrative. Please expand the design basis, and revise the design narrative, (and if necessary one Norrthcarolina 11 atimally North Carolina Division of Water Quality 1617 Mail Service Center Raleigh, NC 27699-1617 Phone (919) 733-7058 Customer Service Internet: www.ncwaterauality.org Location: 512 N.

I am removing the siphons. b. J have drawn a line thru the wier at elevation 14.0 feet on page 2 of the plans. This is the highest elevation of standing water during normal operations. This provides one foot of Gee board. c.'Curbing has been added. 'd. The design as submitted does not attempt to control over -flow during flooding (heavy rainfall events) because all over flow waters will find their way to the storm water treatment pond. However, I have raised the walls of the wash pit by 0.5 feet to force flood waters to exit over the lip of the wash pit. Item 2 a. Wash down water from the truck loading area is estimated not to exceed 200 gallons per day. This water will flow along the side of the road, thru the culvert shown on the plans to the storm water treatment pond, a distance of about 400 feet. Consider that these soils are sandy and porous. The percolation rate for modified soils at the surface would be one gallon per square foot per hour and below the surface as much as 3.96 cubic feet per hour per square foot as is shown at other locations in this permit application. The average slope is 3.6 feet over 400 feet. The velocity of a small stream on an irregular surface flowing over a width of one foot is about 0.5 feet per second. Therefore, the travel time is 800 seconds_ The estimated wash Page 2 of 2 down titne is 15 minutes. 'Therefore, over the time period of 15 minutes plus 800 seconds or 28.33 minutes we should expect (28.33 min160 minutes per hour x lgal/hour per square foot x 400 square feet) 188 gallons to percolate into the ground Therefore, the wash water will not get to the treatment pond except during heavy rains. =0 1 g8 9 n L r-- Irrigation water from the stock pile area is routed along the edge of the road and thru the culvert (same as above). These waters are expected to reach the pond only during heavy rain events. Consider a 40-foot diameter stone or sand pile. The area would be 1256 square feet. These soils can absorb one gallon per square foot per hour or 1256 gallon per hour after the pile is saturated. This will require a -me of flow of about 21 gallon per minute. Also there will be a supervisor available to turn off the water supply when surface flow begins. There will be no adverse impact on the stormwater pond should the irrigation water reach he pond. Trunk rinse off will be done on the truck wash pad. b Calculations have been revised to show freeboard. sin y L. Richardson, PE ?4� e, 1- 4 � AC ! L. rti.* ri &-y e ►t_-1 Aot T es r?

After all my comments were addresses and revisions made, a state SW permit was issued on March 20, 2007. 1 don't see any problems with issuing them a NCG14 permit. Thanks Samir Bill Moore wrote: Ken Pickle wrote: Bill, I have an NOI from ABHW Concrete; the owner is Manfred D. Alligood, Jr. He is proposing a ready -mixed facility out Pactolus Highway, in the Wharton Station area. Their discharge would be to an unnamed tributary to Maple Branch to Tranters Creek, both being class C Sw NSW waters. The proposed wastewater recycle and treatment facility meets our requirements under NCG14 and their NOI is in order. I intend to issue them COC NCG140369, pending your favorable concurrence. Do you want to see the NOI? Do you need to make a site visit? (undeveloped site - 1 believe this is a new facility.) Any comments or concerns? Ken Good Morning Ken, Hope you and all the sw folks in the middle part of NC are doing well. Samir issued state sw permit (SW7061128) for the ABHW Concrete facility on 3/20/07. I will defer to him re. review of the NOI/NCG14 for this facility. While we are on the subject, on 5/1/07 1 issued state sw permit (SW7061113) for the DPD Properties ready mix plant located near Bayboro/Pamlico County. This is also a new facility. During the review of the state sw permit, I advised the owner by letter that a Fed sw permit would be required & provided all the necessary contact info to obtain the NCG14. Their engr responded & stated that the owner would apply for NCC14 prior to operation. If you need additional info re. this facility, let me know. During the state sw review process, I am trying to determine those facilities that require coverage under the Fed sw program and advise the owners of the Fed requirements. But, I am not letting the Fed process hold up the issuance of the state sw permit. Should we send copies of the state sw permits and/or the correspondence to DWQ/Stormwater Group ? In most cases, the owners are ready to build the minute they receive their state sw permit; but, if they haven't applied for their Fed sw permit, I question whether they will receive their Fed sw permit prior to beginning operation ? Another question for the "movers & shakers". Have a great day, later. of 1 5/9/2007 9:51 AM COC No. NCG 140369 Mr. Manfrud D.
