52.252-3 ALTERATIONS IN SOLICITATION (APR 1984)

Portions of this solicitation are altered as follows:

P00001 - No alterations to SOW or attachments. Quote due date extended to 22-June-2018. Answers are being provided in response to questions.

(End of Summary of Changes)

Surface Water and Sediment Remedial Investigation Scope of Work

DSC McLouth Steel Gibraltar Plant Gibraltar, Michigan EPA Site ID No. MIN000510362

USACE response to contractor questions are in green.

1. Can we get a week’s extension for the due date until June 22, 2018?

Response date has been changed to 22 June 2018.

The SOW and the FSP, QAPP, and SSHP have some differences that need to be clarified.

2. The FSP says on page 4‐1 that the USACE and its subcontractors will establish:

* Field trailer

* Storage container

* Portable sanitary facilities

* Temporary IDW storage area

* Dumpster

* Equipment Decontamination area

The SOW says on page 9 USACE and its subcontractors will establish:

* Temporary IDW storage area

* Dumpster

* Equipment Decontamination area

Who will be providing the portable sanitary facilities?

The Contractor shall provide the portable sanitary facilities.

3. Clearing and grubbing is to be done to provide safer access for sampling activities. If we need to move dirt to build sloped access ramps for safer access to the ponds, is that considered clearing and grubbing or building of roads? Will it be allowed in area where there are no landfill caps to impact?

That should be considered as ‘construction of gravel access roads’ and should be considered within the lump sum proposal. No landfill caps are near the proposed project areas and access ramps will be permitted to gain access to the ponds/basins.

4. If we install sampling docks/pads to assist in getting the samples to the geologist/engineer on shore, can they be left in place, or would they need to be removed?

Yes, they can remain in‐place.

5. What are the work hours estimated for this project? What hours will the site be open? 7 am to 7 pm?

6 am to 9 pm (dawn to dusk)?

The site will be able to be accessed from 7 am to 7 pm.

6. The FSP says 2 rounds of surface water sampling, the SOW says nothing about a second round of sampling. Are we to provide pricing for only one round of sampling?

This SOW is for one round of sampling.

7. The SOW says the surface water samples will be collected from 8 locations and composited for one sample. Do we need 8 coliwasas or bailers per pond, or can the same sampler be used throughout the pond, and a new sampler per pond, or can the samplers be decontaminated between samples/ponds?

Do we need different or additional sampling equipment for the discrete sample locations for the VOC sampling?

One coliwasa can be used per pond. A new coliwasa shall be used at each pond. Additional sampling equipment for the VOCs is not required.

8. Most bailers and coliwasas are 3‐4 feet in length. If the water is deeper than 3 feet, will we need to provide alternative sampling equipment to get sample from the entire water column?

One sample from the approximate center of the vertical column will be sufficient.

9. Will the engineer/scientist be on the boat to assist in the collection of the water? or will they be in their own boat?

Yes, if there is sufficient space aboard the boat, the engineer/scientist will be onboard to assist in sample collection. If not, the contractor will collect the sample from each discrete location with a coliwasa and transfer the water to a 10‐liter collapsible container (will be provided by USACE). The container will then be transferred to the engineer/scientist for processing.

10. Will you provide the winning bid the GIS files with the sample location coordinates?

The sample location coordinates will be provided to the Contractor post award.

11. Who will do the water quality monitoring of the various parameters (SOW page 9)? Will the samples be monitored or the ponds? It just says during sampling monitoring will occur.

If there is sufficient space aboard the boat, the engineer/scientist will be onboard to assist in measuring surface water field parameters using a Horiba U‐52 multi‐parameter instrument (or similar equipment).

If not, the contractor will measure the field parameters.

12. If the water samples are to be collected prior to sediment sampling to reduce the impacts, what about the impacts from launching the boat, and moving around the pond? If there isn’t enough water, then just moving the boat from one sample location to another could impact the water sample. Will anchoring be required to hold the boat in place while water sampling?

Impacts from launching the boat will be unavoidable. Care will be used to cause as little disturbance as possible. Anchoring is not required while collecting surface water samples.

13. Does water sampling and sediment sampling have to occur on the same day? Can different boats be used to collect the water and sediment samples?

They do not have to occur on the same day. Different boats can be used to collect the water and sediment samples.

14. If the water is too shallow to allow access by boat to a sample location, will the location be moved, or will another sampling vessel be required?

Another vessel would be required. Alternatively, the samples could be collected by wading into the pond.

15. If the sample locations is located near the edge in vegetation, will the location be moved, or will the vegetation need to be removed prior to sampling? How should the impacts to the water sample be handled? Should water sampling be delayed?

Sample locations may be moved based on field conditions. Some impacts will be unavoidable. Care shall be used to cause as little disturbance as possible.

16. Can we install markers, buoys, stakes, where the samples are to be located?

Yes.

17. Can we inspect the ponds before mobilization to sample to determine sample locations and water depths?

Yes.

18. Do the sediment samples have to be contiguous? If using a geoprobe with a 5‐foot sampler, would that be acceptable?

The sediment samples shall be contiguous.

19. Will the engineer/scientist be on the boat to PID the sample? Or will each sample have to be brought to shore for opening?

Yes, if there is sufficient space aboard the boat, the engineer/scientist will be onboard to assist in sample collection and screening with the PID. If not, the contractor may screen the sample aboard the boat or transfer it to shore for screening.

20. What is the recovery is poor? e.g. push 8 feet and only get 2 feet of sediment.

Additional samples shall be required in the case of poor recovery.

21. Who is to provide the drums for the sediment waste?

The contractor shall provide the drums for sediment waste.

22. Who is to provide for the disposal of the drums of sediment waste?

The drums shall remain on‐site in a designated staging area pending eventual disposal at one of the on‐ site landfills.

23. When is the drum disposal of sediment waste to occur? At the receipt of analytical results, end of project, end of the calendar year?

The drums shall remain on‐site in a designated staging area pending eventual disposal at one of the on‐ site landfills.

24. Why isn’t the excess sediment being returned to the pond?

The USEPA required that all sediment waste be placed into drums and not returned to the associated pond.

25. The SOW doesn’t say anything about Level C and a respirator plan. The FSP says modified Level D.

The SSHP has different information. Who is doing the real time monitoring?

The Contractor is responsible for the safety of their workers; however, the sampling is anticipated to be performed using Level D PPE. The contractor shall perform monitoring of the breathing zone using a PID and/or MultiRAE PLUS or QRAE (or similar equipment), and if warranted, shall switch to Level C PPE per their accepted APP/SSHP.

26. Who is doing the dust monitoring and when? Does it only need to be done if/when we are building roads, clearing and grubbing, or during the whole time of sampling?

Dust monitoring is not required for this work.

27. Who is responsible for hosting the daily safety tailgate meeting?

The contractor shall be responsible for hosting the daily tailgate safety meetings.

28. Do the contractors need the blood‐borne pathogen training?

USACE has no requirement for this training.

29. Respirators and Level C. Do all employees on site need Level C respirators even if only doing grubbing and clearing or administrative work?

Respirators and Level C PPE are not anticipated to be required during grubbing and clearing or administrative work; however, the Contractor is responsible for the safety of their workers.

30. Do we need to set up a site control area/contamination reduction zone for each pond where we are launching, staging, and decontaminating equipment?

No, the shoreline where the vessel is launched and decontaminated shall act as the contaminant reduction zone for the vessel.

31. Will the scientist/engineer have to go through the CRZ and be decontaminated every time a sample is brought to shore? or will they be working in the EZ/CRZ?

They will be working in the EZ/CRZ.

32. Page 27 of the SSHP says USACE personnel will be using a PID for VOC and SVOC monitoring. The PID will be donned suing a Personal Exposure Vest for direct continuous breathing zone monitoring. Does this mean a USACE person will be on the sampling boat during all sampling activities?

Yes, if there is sufficient space aboard the boat, the engineer/scientist will be onboard to assist in sample collection and screening with the PID.

33. The SSHP seems to be concerned with phenols and carbon disulfide. Who is to provide the monitoring badges and/or dragger tubes described on page 28?

The Contractor is responsible for the safety of their workers; however, the sampling is anticipated to be performed using Level D PPE. The Contractor shall perform monitoring of the breathing zone using a PID and/or MultiRAE PLUS or QRAE (or similar equipment).

34. The SSHP page 30 says work clothing requires Saranex coveralls and booties for water and sediment sampling. Is this correct? Is this protective clothing also required for the decontamination procedures?

The Contractor is responsible for the safety of their workers; however, the use of Saranex coveralls is recommended for sampling and decon procedures.

35. If personnel are not able to be upgraded to Level C, the Work will be stopped until monitoring has shown that the air levels have reduced to Level D?

Correct.

36. Who is responsible for monitoring the wind direction?

The contractor shall monitor wind direction. A short piece of warning tape can be affixed to a secure upright to serve as a wind direction telltale.

37. The SOW says the solicitation requires a Lump Sum Price. Do you need a price breakdown or just a single price?

Please submit the total lump sum price to perform the work described within the SOW and clarified by the Q&A.

38. The SOW asks for a narrative? Is there a page limit or other requirement for the narrative?

Please submit a narrative no longer than two 8.5x11 pages.

39. Can the schedule included in the narrative be a Gantt Chart (bar chart)?

Yes.

40. The basis for award says the “responsible contractor that offers the lowest price” does this mean the proposal with the technically acceptable lowest price?

No, this is not LPTA and the contractor will not be evaluated against minimal technical and performance standards. Responsibility will be established prior to award in accordance with FAR Part 9.1. FAR Part

9.104 details the standards necessary to be determined responsible. The apparent low price contractor may be required to complete a pre‐award survey if limited information is available. The survey is more in‐depth than what is being requested at this time. The request for the schedule correlates to FAR 9.104(b), and narrative to 9.104(e) and (f). The System for Award Management (SAM) database, Federal Awardee Performance and Integrity Information System (FAPIIS) database, and Past Performance Information Retrieval System (PPIRS) will also be used to supplement this determination.

41. Can the current occupants of the facility provide the water necessary for the decontamination? Or will that need to be brought on site daily?

Potable water for decontamination will be available on‐site.

42. Will weekend (Saturday & Sunday) work be allow during the project?

Yes. A 10‐day on, 4‐day off schedule would be acceptable.

43. On Page 6 of the Scope of Work:

* 3.1 Task 1: Document Review and Pre‐bid Onsite Meeting Prior to conducting a site visit, the Contractor shall review, at minimum, the following three documents:

* • USACE Buffalo District, 2017, Field Sampling Plan, DSC McLouth Steel Gibraltar Plant, Gibraltar, Michigan, December.

• USACE Buffalo District, 2017, Quality Assurance Project Plan, DSC McLouth Steel Gibraltar Plant, Michigan, December.

* • USACE Buffalo District, 2017, Site Safety and Health Plan, DSC McLouth Steel Gibraltar Plant, Michigan, December.

* Can the Corps please provide these Documents These attachments have been posted on FEDBIZOPS.

44. Will the Corp be providing coolers and ice for sample transport to the laboratory or is it expected that the contractor will cover these logistics?

Laboratory analysis is covered under a separate contract with the USACE. The Contractor shall help collect the samples, however the USACE will be responsible for obtaining sample bottles/jars, labeling and icing the samples, and coordinate with the laboratory contractor for sample pick‐up at the site.

45. Will there be a site walk for this project? I did not see one mentioned in the RFP. If not, is it possible for my team and I to visit it on our own? We are within close proximity to it.

A site visit was posted on FEDBIZOPS and occurred Friday, June 8, 2018, at 10:00am.

46. Who will be obtaining the sample bottles from the Lab?

Laboratory analysis is covered under a separate contract with the USACE. The Contractor shall help collect the samples, however the USACE will be responsible for obtaining sample bottles/jars, labeling and icing the samples, and coordinate with the laboratory contractor for sample pick‐up at the site.

47. Are lab costs to be included in the bid, or will the samples be analyzed under a different contract?

Lab costs shall not be included in the Contractor’s proposal. Laboratory analysis is covered under a separate contract with the USACE. The Contractor shall help collect the samples, however the USACE will be responsible for obtaining sample bottles/jars, labeling and icing the samples, and coordinate with the laboratory contractor for sample pick‐up at the site.

48. Page 10 of the SOW says a 2‐inch diameter cellulose acetate butyrate core tube. Can a 3‐inch or 4‐ inch diameter sampling tube be used?

Please send a copy of Appendix B of the FSP.

A 2‐inch tube was mentioned to limit the amount of excess sediment, however a 3 or 4‐inch tube can be used, if it will allow for a better sample to be recovered. The FSP was posted on FEDBIZOPS.

49. Page 12 Section 4 says to provide one original and one copy of the quote. On the FBO page it says we can submit the proposal via e‐mail. Do you still want one original and one copy?

No, everything can be submitted via email and one version is sufficient. If you chose to submit via mail, please include an original and a copy.

50. The figures do not show the location of Quarry Lake. Please provide a map of Quarry Lake.

Quarry Lake is depicted on Figure 4‐1B of the FSP, which has been posted on FEDBIZOPS.

51. Staging location for the IDW. Will each figure have its own IDW location, or will there be only one for the project? Will both figures need a rented dumpster for trash and a mulching area for cut vegetation?

There should be one staging location for IDW near Countywide Landfill and one staging location near the leachate treatment lagoon system, selected upon initiating the project. One dumpster (minimum 10cy) for trash should be sufficient that should be staged near Countywide Landfill. Cut vegetation shall be placed adjacent to the associated pond/basin, out of the way of operations.

52. Can the SSHO and the QCM be the same person?

Yes, if they are qualified to perform both duties and the duties of one position doesn’t interfere with the duties of the other position.

53. Is construction of a gravel road necessary? Our equipment is quite mobile and designed for these settings, and we feel that this step will add a potentially unnecessary cost based on our extensive experience providing vibracore services in similar settings.

No, construction of a gravel road is optional, dependent on contractor equipment requirements.

54. How much time will USACE require to process the collected vibracores on‐site Once the tubes are cut open, USACE will require approximately 20 minutes to process the samples.

55. Will the contractor be allowed to select the DoD ELAP accredited lab, or will USACE Buffalo choose the laboratory?

Laboratory analysis is covered under a separate contract with the USACE. The Contractor shall help collect the samples, however the USACE will be responsible for obtaining sample bottles/jars, labeling and icing the samples, and coordinate with the laboratory contractor for sample pick‐up at the site.

56. Does RTI Laboratories, Inc. have to be used as the environmental lab per the UFP‐QAPP?

Laboratory analysis is covered under a separate contract with the USACE. The Contractor shall help collect the samples, however the USACE will be responsible for obtaining sample bottles/jars, labeling and icing the samples, and coordinate with the laboratory contractor for sample pick‐up at the site.

57. Is RTI Laboratories, Inc. currently under contract with USACE Buffalo to provide laboratory services?

Laboratory analysis is covered under a separate contract with the USACE. The Contractor shall help collect the samples, however the USACE will be responsible for obtaining sample bottles/jars, labeling and icing the samples, and coordinate with the laboratory contractor for sample pick‐up at the site.

Section 3.3.4 Sediment Sampling states that the “vibracore may utilize a 2‐inch diameter cellulose acetate butyrate (CAB) core tube (core catcher end down) up to 10 feet in length… The tube will be vibrated into the sediment until it is inserted 10 feet or until refusal occurs.” Questions include:

58. Are 2‐inch diameter core tubes required? (we have found that larger diameter sediment core tubes have much better recovery in soft sediment) A 2‐inch tube was mentioned to limit the amount of excess sediment, however a 3 or 4‐inch tube can be used if it will allow for a better sample to be recovered.

59. Can Lexan be substituted for CAB?

Yes.

60. Is there a percent recovery requirement for the sediment cores? For example, 80% recovery means that 8‐feet of sediment core is obtained from a 10‐foot push. We have found that 2‐inch diameter core tubes can have poor recovery (50% or less) in soft sediment which greatly complicates interpretation of the field and laboratory data.

A 2‐inch tube was mentioned to limit the amount of excess sediment, however a 3 or 4‐inch tube can be used if it will allow for a better sample to be recovered. A minimum 50% recovery is required.

70. Can we use sediment coring equipment other than vibracore?

Yes, if the equipment can meet the sediment collection requirements as specified within the SOW.

71. Does the USACE provide the construction trailer, potable water, dumpster for disposal of core tubes, and bathroom facilities or does the contractor?

A trailer is not anticipated to be needed for this portion of the RI. Potable water for decontamination will be available on‐site. The Contractor shall procure the dumpster, for disposal of municipal waste, and portable sanitary facilities.

72. The Site Safety and Health Plan (Section 8.1 Levels of Protection, pg.31) indicates that Level D+ or Level C will be required for intrusive activities. The upgrade to Level C is triggered by photoionization detector (PID) readings (pg. 28 of the SSHP). Questions include:

73. Will USACE or the contractor be required to conduct the PID air monitoring during intrusive activities?

The Contractor is responsible for the safety of their workers; however, the sampling is anticipated to be performed using Level D PPE. The contractor shall perform monitoring of the breathing zone using a PID and/or MultiRAE PLUS or QRAE (or similar equipment), and if warranted, shall switch to Level C PPE per their accepted APP/SSHP.

75. Based on the SSHP, do all personnel that may be involved with intrusive activities (sediment coring, construction of gravel access roads, etc.) required to have training and equipment to upgrade to Level C?

The Contractor is responsible for the safety of their workers; however, it is anticipated that only personnel performing the intrusive activities (i.e. collecting the samples) would be required to have training and equipment to upgrade to Level C, based on monitoring of the breathing zone. Level C PPE is not anticipated to be required during construction of access roads or grubbing and clearing activities.

76. We have a question regarding the RFP. Must the sediment sampling be performed using Vibra Core techniques or can the samples be collected by grab techniques? Also please confirm that there is no there is no laboratory analysis or final reporting requested. Is there the possibility of extending the due date by 7 days to provide additional time for a final response?

Other techniques may be used, if the equipment can meet the sediment collection requirements as specified within the SOW. No laboratory analysis or final reporting is required under this SOW.

Response date has been changed to 22 June 2018.
