Schuttler Date January 3, 1983 Based on a review of your VCM sampling and analysis methodology, I am providing specific recommendations to improve quality control. The following VCM sampling and analysis papers by Jack Larkin were reviewed: 1. Personnel Monitoring for VCM Exposure Utilizing the 3M Brand Organic Vapor Monitor (OVM) #3500, December 15, 1980. 2. Use of Higher Capacity Badges for VCM Monitoring, June 4, 1982. (Each paper is enclosed in Attachment I). Reviews were provided by R. G. Badger, OCC Central Sciences and Dr. F. W. Snowden, 3M, Occupational Health and Safety Products Division. Their reviews are presented in Attachment II. The major concerns with Larkin's papers are: 1. Air bags are not an acceptable device for exposure chambers in validating Organic Vapor Monitor performance. A dynamic flow chamber must be employed to provide meaningful results. 3M has conducted validation tests for VCM using a dynamic flow chamber. Thus it is unnecessary to validate the use of 3M OVM badges. 2. The inference of #3500 (one-bed) badge capacity presented in paper 1 is incorrect. As discussed by Snowden, the capacity or linear range in the #3500 badge depends on the exposure history but testing in a bag provides misleading data. Since the linear range for #3500 badges may be quite low for 8 hour samples, I recommend that the #3520 or double wafer badge be used for sampling all Group 1 employees. The weight relationship of VCM on each wafer of the #3520 badge will indicate if a valid sample was collected (i.e., if the weight response is linear). For the #3520 badge, "to assure a valid sample under all sampling conditions, the ratio of the contaminant weight (Ws) on the second adsorbent to the contaminant weight (Wp) on the primary absorbent must meet the following criteria: Ws/Wp < 0.50"*. *Anders, L.W., et al, Organic Vapor Monitor with Backup, Section #3520. 3M Company publication. (No date given). 2149E-1 OCC 8167 2- - 3. The conclusion in paper 2 that, "the double badqes do not perform in the manner suggested by the manufacturer's literature", is untrue and appears to follow from a lack of understanding of the operatinq principle of the #3520 badge and faulty experimental technique. See Snowden's review for a discussion. The #3520 badge and the similar 2-section badge by DuPont are based on sound technical principles and have been lab and field validated. 4. To criticize the recommended analytical procedure when that procedure was not followed (paper 1, section A), indicates faulty experimental desiqn. The 3M analytical method is simply an adaptation of the NIOSH Standard Method for VCM. DMAC is a less efficient solvent than CS2 which results in less complete desorption of VCM from the badge. The use of either solvent may give accurate and reproducible results however. Since you are using a non-standard method, I recommend that split sampling be conducted periodically and one of the samples sent to an AIHA certified lab for analysis to compare with the Works Lab results. This will provide technical support for the DMAC-Head Space method. Recommendations To summarize, my recommendations are: 1. The VCM sampling proqram should use #3520 badges for Group 1 employees and to retest other employees when sample results show greater than 1 ppm, 8 hour TWA. 2. The analysis of #3520 badges must be performed separately for each wafer and the VCM weight for each wafer added using the following equation: C (mq/m^) = (Wp + 2.2 Ws) Kp + t Where: Kp = samplinq rate of the contaminant onto the primary adsorbent. t = length of samplinq period. Wp = corrected weiqht collected on the primary adsorbent. Ws = corrected weiqht collected on the secondary adsorbent. 3. Validation data should be collected on the VCM analytical method by conducting selected split personal sampling and sending one of the samples from each set to an AIHA certified lab for comparison. 2149E-2 cc 8168 TO MR.

LARKIN REFERENCE SUBJECT PERSONNEL MONITORING FOR VCM EXPOSURE UTILIZING THE.3M BRAND ORGANIC VAPOR MONITOR #5500 RECfcilvfc-O Guo i o 1980 G. D. L! OYD History: Up to the present, personnel monitorin' for vinyl chloride monomer (VCM) exposure, as required by the Occupational Safety and Health Administration (OSHA), has been carried out usin' ten minute air sampling bags and standard 'as chromatographic analysis. In order to convert to use of the 3M Brand Organic Vapor Monitor #31500 and to utilize our automatic headspace gas chromatograph and computin' integrator, a study has been initiated to establish operating parameters and validity of data obtained. Summary of Results: 1. To avoid handling the volatile and highly toxic solvent carbon disulfide, dimethyl acetamide was used as the desorbing medium in this investigation. 2. The desorbinr technique suggested by 3M literature was found to yield incomplete recovery thus producing inaccurate results. 3. A technique was developed wherein the charcoal disc of the J>K bad'e was transferred to a test vial of the F40 headspace gas chromatograph and desorbent added directly to the sealed vial via hypodermic injection. 4. A response factor for standard VCM concentration was derived as part of the programming of the Model I computing integrator. 5. A VCM concentration value was determined using standard 1.01 ppm VCM in air, also necessary for programming the Model I. 6. It was determined that the Model I may he programmed to print out ppm VCM exposure directly as 8 Hour Time Weighted Average. 7. Numerous analyses were run on bad~es placed on different plant personnel for 8 hour periods which produced data consistent with that expected. 8. Additional analyses using higher standard samples, 10.1 ppm and 20.0 ppm VCM, indicate linearity of results up to the saturation level of the discs. Conclusion: ae. The method of analysis developed in this investigation offers an accurate, and relatively simple and rapid, determination of 8 Hour Time Weighted Average VCM exposure utilizing the 3M Brand Organic Vapor Monitor #3500. /A.

The procedure proposed by Perkin-Elmer Corp. to utilize their F40 headspace gas chromatograph with Model I computing integrator to determine levels of VCM adsorbed by activated charcoal surests several desorbents other than carbon disulfide (CS^). To minimize volatility and avoid working with the highly toxic CS2, dimethylacetamide (DMAC) seemed to be the most promising alternative and was thus used in this investigation. 3H Brand Organic Vapor Monitor #3500 is a plastic badge containing activated charcoal imnressed in an inert matrix in the form of a disc about 1/2 mm thick by 30 mra in diameter inset in the badge and covered by a permeable mem brane. The disc is exposed to sample atmosphere and VCM is adsorbed by the charcoal by diffusion of sample atmosphere across the face of the membrane. The suggested handling procedure is that at conclusion of exposure time the badge be recealed and derorbent be introduced for a period of time (1 ml DMAC for 1/2 hour with ueriodic agitation). After desorbtion, the DMAC is analyzed by gas chromatography to determine VCM content. Data obtained is incorporated in calculations to determine Time Weighted Average VCM exposure. This procedure was applied to a 3M badge exposed for 8 hours to an atmosphere containing 10.5 ppm VCM and the entire 1 ml portion of DMAC was transferred to a headspace vial, sealed, equilibrated for 1/2 hour at Q0C and analyzed using the F40 and Model I. The Model I was programmed to convert the VCM peak signal data to pna VCM contained in the vapor space of the vial. Transfe of the DMAC to the vial is somewhat arbitrary as one cannot transfer all the DMAC initially introduced to the bad'-e. In this analysis, a value of 138 ppm ^ VCM was obtained. To determine totality of desorbtion, a second 1 ml portion of DMAC was added to the previously desorbed badge and the process of analysis repeated. The second run yielded an additional 143 ppm VCM. A third DMAC addition was made and an additional 78 ppm VCM obtained. Finally, the disc which had been desorbed three times was removed from the badge, cut into small pieces, placed in a headsnace vial and 1 ml DMAC added. The result, an additional 23o ppm VCM. Obviously, the desorbtion using the 3M technique is neither complete nor accurate. B. On the basis of the data obtained in A, it was decided to remove the charcoal disc from the badge upon completion of exposure, cut the disc into pieces and place the entire disc in a vial for desorbtion. Numerous standard samples were prepared as follows: An opened badge was placed in a 15 liter air bag through a slit in the bag, the. bag was then resealed and filled with 1.01 ppm standard VCM in air. After 8 hours, the hadge was taken from the hag, the disc removed, cut into pieces and the pieces sealed in a headspace vial. 1 ml DMAC was injected into the vial, the vial was equilibrated 1 hour 90C in the F40 and analyzed using the F4o and the Model I. In order to obtain integrated data directly in ppm, it was first necessary to establish a response factor (RF) for VCM standard sample. This was done according to Quantitative Method 3 of the Model I operations manual. Over a period of weeks, three vials were filled each day with standard 10.5 ppm VCM in air, sealed and 1 ml DMAC added. Each vial was analyzed using the F40 and Model I and an RF obtained. Statistical analysis of the resulting data yielded an RF of 3085 (see Page A) having a Standard Deviation of 236 and a 95# Confidence Limit of 37.4 which is 2.83# of the RF. It should be noted that without the 1 ml of DMAC the RF would be 300-350 units higher indicating OCC 8170 -2- an established eouilibrium in the vial where about 90$ of the available VCM C is in the vapor space and 10$ in the DMAC. Using the PF of 3085, the Model I was programmed to print out the concen tration in ppm of VCM in each vial containing a charcoal disc exposed to 1.01 ppra VCM standard for 8 hours. Statistical analysis of the data obtained for samples ran over a period of weeks yielded an average of 109.6 ppm VCM (see Page B) having a Standard Deviation of 5*21 ppm and a 95$ Confidence Limit of 2.8 ppm which is 2.56$ of the average. This means that a vial prepared and .treated as described above contains 109.6 ppm VCM by volume in the vapor space, this being the VCM desorbed by the DMAC. Since the volume of the vial with 1 mj DMAC is 22.5 ml, the actual VCM in the vapor space by weight is 6.89 X 10 rrams. However, as will be shown, it is not necessary to convert to weight VCM on each analysis. C. Utilizing the RF of 3085 and the 1.01 ppm VCM standard concentration of 109.6 ppm VCM, the Model I may be orogrammed so that for an unknown sample the VCM peak signal from the F^O will be reported on the Model I printer tape directly as 8 Hour Time Weighted Average VCM exposure in ppm by volume. For example, a badge was placed on a reactor operator for a period of 8 hours. At conclu sion of exposure, the badre was sealed and returned to the laboratory. The badge was opened, the disc removed, cut into pieces, transferred to a headspace vial and the vial sealed. 1 ml DMAC was added to the vial and the vial was equilibrated 1 hour @ 90C in the sample holder of the F40. The Model I was programmed with the RF of 3085, the average 1.01 ppm VCM standard concen tration of 109.6 and an expoential value of 3 to properly position the decimal point. The vial was then analyzed according to standard F4o operational pro cedure and VCM peak signal as produced by the chromatographs FID was converted by the Model I directly into 8 Hr. TWA VCM exposure of 2.1 ppm. See Page C for numerous examples of analyses run on various plant personnel. D. Additional analytical work using VCM standard of 10.1 ppm for the 8 hour exposure indicates that as the level of VCM in air increases, the charcoal disc adsorbs in a linear manner. The average of a number of 10.1 ppm standard air bags was 10.5 ppm by analysis, not considered to be indicative of non linearity. Samples were also crudely prepared at a target of 20.0 ppm and these also indicated linearity of data. The manufacturer indicates the badge will adsorb up to a level of 30.0 ppm VCM before saturation occurs. E. Considerable time was devoted to establishing the proposed method and neces sitated use of many 3M badges. Any evaluation of other monitors or desorbing agents would involve repeating much of the experimental procedure.

Two double badges were individually exposed in air bags to 10.1 ppm VCM standard for a period of S hours. The badges were then dis embled and the front and back adsorption discs were cut into small pieces and sealed in headspace vials with 1 ml SMAC. The -vials were then analyzed using our headspace gas chromatograph with computing integrator programmed to yield the VCM concentration directly as 8 hour TWA. For one badge, the front disc showed 7*4 PFn VC^ and the back disc J.O ppm VCM. The other badge Showed 7.9 ppai VCM on the front disc and 2.9 ppm VCM on the back disc. Average for the two runs was 7.65 ppm on the front disc and ?.95 PPEi on the back disc, a ratio of about 70-50 front to back. ( past work with single badges indicated complete adsorption of ;he 10 ppm standard on the single disc. B. Six sets-of- badges, one single and one dpuble, were hung or| productior personnel anticipated to have high levels of exposure. As it turned out, high levels were not experienced; however, this was a condition over which we had no control. Regardless, after 8 hours exposure, the single badges discs and the front an$ back discs of the double badges were individually analyzed. In npst instances, agre e merit between the single badge disc and the total of the double badge data was good. However, in|every case, despit e gene rail; low to very low exposure levels, VCM was found on the back d:-se and at about the same ratio as was found with, the 10.1 ppm VCM standard. See Table I. At these low levels, and based on our work wi th single badges, no permeation to the back disc would have been expe cted to occur. In an attempt to establish whether equilibria between front disc and back disc was bei reached regardless o levels of concent ratio double badges were exposed in air bags to n.Qt ppm VCM and 10.1 ppm VCM standards for 24 hours, naturally, due to the prolongs d exposure time, the levels of VCIi were expected to be higher than for a normal 8 hour exposure. In these two cases. tbd 95 ppm standard showed 0.8 ppm on the front disc and 0.7 ppm on the back disc and the io.i ppm standard showed 11.2 ppm or. the fron disc and 11.0 pp: on the back disc. It would appear that over an extended period of time equilibria is established between the front and back disc r<egard less of concentration. It is felt that this confirms the approafimately 70-50 equilibria ratio observed after S hours exposure. D. From the abo%fe data, plus the data deterti ined in our initid! work with the single badges, it is concluded hat the double bad ges are noi performing in the manner indicated by th^ manufacturer's li terature; that is, the front disc adsorbing until :he saturation levs 1_L. iJ.ffc,reached before breakthrough to the back disc occurs.

Briggs________________________________________ Date July 30, 1982 R. G, Badger A* ^___________________________ An at lysis of 3M Organic Vapor Monitors at Pottstown cc: D. Eichler R. J. Schuttler TIC (1) This memo is a response to your request for comments on the report "Personnel Monitoring for VCM Exposure Utilizing the 3M Brand Organic Vapor Monitor #3500." Based on what is said in the report and 3M literature relative to the use and calibration of these badges, the following points should be noted: 1. The use of air bags (with static atmospheres) for the exposure of the badges to a standard atmosphere is not a valid technique. Even though good comparative results were obtained at 10 and 20 ppm, this may not be an accurate indication of the exposure levels experienced under field conditions due to the difference in air velocity across the face of the badge. 2. The initial attempts to desorb the VCM using OMAC do not invalidate the desorption technique suggested by 3M since DMAC was not suggested as the elutant. 0SHA literature indicates that C$2 should be used to desorb VCM from charcoal. The response factor determinations indicate that DMAC is a relatively poor solvent for VCM and thus it would not be expected to desorb VCM from the charcoal with any degree of efficiency. As a result of these observations it would seem to be prudent to do some additional work to validate the results we are obtaining using this analytical method for these badges. As we have discussed, badges could be exposed in recommended test chambers and run (perhaps blind) in house or duplicate exposures could be taken on plant personnel with analytical work being done both in house and outside. Another alternative might be to use direct spiking of the badges as is done when determining the recoveries in conventional elutriant techniques.

OCC 8179 Summary of Results: 3. Conclusion incorrect, see Text Part A. Experimental Procedures. A. To demonstrate the difference between the #3500 and the #3520 monitors it is necessary to consider the phenomenon as well as the resulting numbers. First, we do not recommend exposure in a plastic bag because of the lack of air movement, and the fact that in many instances it leads to inaccurate and non reproducible results. However, when exposed to a VCM concentration of 10 ppm the #3500 may adsorb, given enough time and a sufficiently high concentration enough VCM to yield an analyzed concentration of 10 ppm. What is not indicated by a single wafer is that the adsorption of VCM is occuring in a non linear fashion. That is, the amount of VCM adsorbed is not proportional to the actual concentration in the air. Some of that which is adsorbed is lost back to the atmosphere. Over the entire exposure range recommended in our literature for VCM it can be assumed that for every 100 molecules of VCM striking the charcoal, no less than 95 remain. When the actual concentration is higher than the suggested exposure range then less than 95 of the 100 molecules of VCM remain. In fact, it may be significantly less and unknown. In these cases it is suggested that the sampling time be reduced. For the #3520 as this nonlinear adsorption begins in the primary wafer, the second wafer begins to adsorb. That is, the primary wafer loses VCM back to the atmosphere and also to the second wafer. 'This may occur at significantly low concentrations in the case of VCM. Because of this, for the #3520, adsorption of VCM remains proportional to the total weight of VCM adsorbed (the total weight, Wt = Wp + 2.2WS.) Wp is the weight VCM on the primary wafer and Ws the weight of VCM on the secondary wafer). The sampling remains linear and it is expected that 30% could be found on the second wafer. Another way of stating it is that the 3520 is 30% more efficient as a collector. B. What this data demonstrates is that even at this low concen tration the #3520 is more accurate because it is adsorbing linearly while the #3500 is not. The total concentration sensed by the #3520 is always higher, indicating its greater collection efficiency. Using the relationship W-t = Wp + 2.2 Ws the concentrations given in Table I could be recalculated (to do this ppm would have to be converted back to weight, recalculated, then converted back to ppm). But as an approx. #3500 #3520 (front and back) 0.3 1.2 1.1 0.2 0.3 2.5 0.52 2.22 1.90 0.32 0.80 5.13 OCC 8180 C. This is somewhat true. Another more realistic way of stating the observation is that at rather low levels (perhaps anything more than 2 ppm) the front section of the monitor will begin to lose some VCM which will be adsorbed by the back-up section. Over an extended period of time it is possible to reach a point where both wafers have reached their limit of adsorption when exposed to enough VCM (that could be a large amount of a low concentration or a relatively small amount of a high concentration). At this point they will, since they are equal in weight, have adsorbed the same amount of material. D. The graph of the breakthrough curve for VCM is enclosed. It indicates that breakthrough begins to occur at levels far below saturation. Again, saturation is not the most important factor for the front section but nonlinear adsorption (where, for example, of every 100 molecules adsorbed 10 to 15 are lost back to the atmosphere) is. Experimental Procedure A. (1) For desorption, as it is performed in this procedure. Dimethyl Acetamide (DMAC) is used. The desorption coefficients in the 3m literature relate to use of carbon disulfide and in some instances dichloromethane, not to DMAC. Thus, the desorption coefficients are correct, but not applicable to this procedure and must be worked out. (2) It is not necessary to get all the VCM out of the wafer for the test to be valid. It is necessary to get a consistent, reproducible amount out under the same conditions and to determine what that amount is. It would be used in the same manner as our desorption coefficient. (3) The procedure should be performed in the same manner as it is performed for charcoal from charcoal tubes. While the desorption coefficient will be somewhat different, it should not be by much.

Group 1 are employees who work in regulated areas on a daily basis. Group 2 are employees who can or do work in regulated areas but not necessarily on a daily basis. Group 3 are employees who work in non--regulated areas but who might occasionally receive some inadvertant exposure. Group k are employees confined to non-regulated areas. The subgroups "A" in group 2 and "B" in group 3 designate hourly paid employees. During the period of January thru March 1981, we were in the process of revising our Personnel Monitoring System from 10 minute grab samples to 8 hour TWA samples. I have not included the 10 minute sample results for that period since they are rather meaningless and our Mr. T. Briggs advised that Mr. Brustein was not interested in data other than 8 hour samples. Our area monitoring data has not been used to calculate employee TWA's or ceiling exposures and are therefore not included. You should be aware that although respiratory protection is required for exposures greater than 1 PPM 8 hr. TWA, the monitoring results records are not reflective of whether or not such equipment was used for excursions greater than 1 PPM. Further, several jobs which inherently produce higher monitoring results, such as high pressure water reactor cleaning and reactor entry, are mandatory respirator aicv PVC Reslns/PVC Fabricated Products Armand Hammer Boulevard.

Attachment #2 shows drawings illustrating floor plans and yard locations and the remote sample pick up points in each area* Oft ^ i LUJ c OCC 8194 Continuous Sequential Area Monitoring System for Vinyl Chloride-Firestone Plastics Co. The Firestone Plastics Company in its Pottstown, Pennsylvania, PVC operations utilizes five Wilks Miran I units and one Miran II unit along with three-Bacharach units for the purpose of continuous sequential area monitoring for ambient levels of VCM. The Miran units are based on infared spectrometry with the Miran I units being of single band capability and the Miran II unit having a dual band capability. The Miran units are preset and calibrated at 13*9 microns which is the wavelength offering the best VCM response with the least interference from other hydrocarbons making them nearly specific for VCM. The Bacharach units are based on hot wire ionization and readout total hydrocarbons -- that is, they are not specific for VCM. All units are base line calibrated daily. As a practical matter, all data received from both the Miran and Bacharach units is considered to be totally VCM. Bach unit is equipped with a strip chart recorder which registers each sampling point analysis. We do not have the capability of tying these units into a computer to analyze the vast amount of data accumulated. Employee TWA exposures are not calculated from these data due to the complexity of doing such, and personnel TWA sampling is conducted separately. The units are located in "safe area^" such as electrical vaults, with the sampling hoses running from there throughout specific plant areas. Four Miran I units, serving regulated areas, are equipped for analyzing VCM in the range of 0 PPM to 100 PPM. One Miran I unit, serving principally deregulated areas, analyzes from 0 PPM to 50 PPM VCM. The Miran II is not currently in use and serves as a spare. The Bacharach units are equipped for analyzing hydrocarbons -- VCM' in the range of 1000 PPM to 36,000 PPM. The Bacharach units serve only the regulated areas. The Miran units are set to alarm at 10 PPM VCM and 100 PPM VCM while the Bacharach units alarm at 1000 PPM and 36,000 PPM hydrocarbons -- VCM. Whenever any unit senses VCM at an alarm set point both visual and audible alarms respond. Color coded light panels indicating the alarm levels are located at entrances to regulated areas and at other strategic points. A master alarm light panel located in the production foreman's office displays a total readout of all plant sensing points. In addition, each area is equipped with a coded audible alarm to indicate the alarm levels. The lights and audible alarms are coded as follows: VCM Level 10 PPM 100 PPM 1,000 PPM 36,000 PPM Light Alarm^Color White Blue Yellow Rd Audible Alarm--Sound Stutter -* mwK. test Slow Whoop Yelp RespAo SCBf ATTACHMENT # 1 occ 8195 .The light panels are labeled with their respective VCM PPM values and, thru training and on the job experience, the employees are educated as to what VCM levels the audible alarms indicate. The sole purpose of our monitoring system is to provide a vehicle for notifying the employees which type of respiratory equipment is required and to provide a leak detection system - which ties in with our emergency procedures. The sample pickup points are distributed as follows: Miran- Bacharach- Type Unit & Unit Location & No. Monitoring No. Monitoj Identity No. Area Serviced Points Points Miran 100 Miran 200 Building I, 1st.

The Miran and Bacharach units pull an air sample for analysis thru each sample tube (point) once, every 12 minutes or five times per hour. If an alarm level is detected in a Miran unit, the system will cl ar itself automatically once the level r duces b low th alarm s t point. If an alarm 1 v 1 is d t cted OCC 8196 in o Bacharach unit, the unit must be manually reset to clear the alarm once the level is below the alarm set point. With 6l sample points and each point providing five samples for analysis each hour, we have 3^5 air analyses completed per hour. This equals 2,kk0 air analyses per eight hour shift, 7,320 analyses per day, 51*2^0 per week and 2,562,000 analyses per year. We have four technicians supervising and maintaining the monitoring system, two of which are on day shift with one on each of the two back shifts. G. D. Lloyd GDL:mas % # OCC 8197 ATTACHMENT I BLDG.

R. Zavon, M.D. DATE: September 17, 1981 COPIES: G. Lloyd H. Dubec FROM: T. M. Brig^"- v' SUBJ: PVC DUST EXPOSURE y^, 5 33 Hooker Chemical Company In response to your 9/15/81 request for information on locations with PVC dust exposures, all PVC Resins and PVC Fabricated Products plants have PVC dust exposure potential. There have been no quantitative measurements made at any plants, specifically for PVC dust. Total dust and the respirable fraction have been measured at the resin plants and most calendering operations. The highest potential PVC dust exposure levels would be anticipated from PVC resin production, specifically from reactor vessel cleaning, resin sifting and grinding, resin bagging, and rail car loading. Resin production plants are Burlington, Pottstown, Perryville and Addis. PVC dust potential from calendering operations appears low since resin handling is a closed system. Dust levels in calender blending areas can be quite high ^e.g,, Swanson study of Burlington Calendering in 1978 - up to 11 mg/m of total dust). This dust should be essentially all additives. Facilities with calendering operations include Pottstown, Burlington and Salisbury. PVC compounding operations also present some PVC dust exposure. These operations can be quite dusty, however, again most of the dust should be from additives (lead exposures are often high here). Facilities with compounding operations include Burlington, Hicksville, and Perryville (not in operation now but it may be restarted within the next year). PVC dust levels from printing operations should be insignificant. Plants with printing operations include Salisbury, and West Caldwell.
